Store Management
Introduction of Store Management

Store Management refers to the systematic process of planning, organizing, and controlling
the storage and movement of goods within a store. It involves the efficient handling of
materials right from receiving, inspecting, storing, issuing, to maintaining accurate inventory
records. In manufacturing or retail, effective store management ensures uninterrupted
production and customer satisfaction.

Meaning of Store Management

Store management means controlling all operations related to materials and inventory —
ensuring the right quantity and quality of materials are available at the right time, right place,
and in a cost-effective manner.

FIFO

FIFO – First In, First Out

Definition:
FIFO is asset management and valuation method in which assets produced or acquired first are sold,
used or disposal first based on their purchased or manufacturing date.

FIFO is an inventory management method where the oldest stock (first received) is the first to be
issued or used. It ensures that materials are consumed or dispatched in the order they arrive.

Why FIFO is Used:

 To prevent expiry or obsolescence, especially for perishable or time-sensitive materials.

 To maintain quality consistency by using older batches first.
 To minimize waste and write-offs by avoiding stock ageing.
 To ensure accurate inventory valuation in accounting.

🏭 Real-World Example in a Raw Material Store:

 Suppose 100 kg of chemical A is received on March 1, and another 100 kg on March 10.
 When production requests chemical A on March 15, FIFO ensures the March 1 batch is
issued first, even if the March 10 stock is easier to reach.
 This avoids the March 1 batch sitting too long and potentially becoming unusable.

📦 How FIFO is Implemented:

 Materials are physically arranged so older stock is in front or on top.

 Labels or barcodes show GRN date / batch number / expiry date.
 ERP or WMS systems track stock age and suggest pick lists accordingly.
 Staff are trained to follow FIFO during picking and issuance.

FIFO Methods

1. Manual Handling Method

- Bankcards
- In out Rack
- Colour Code Sticker
 System FIFO (ERP/WMS Controlled)
- Barcode Systems/RFID

LIFO
LIFO is an inventory management and accounting method where the most recently received stock
(last in) is the first to be issued or used (first out). The latest materials go out first, and the older
ones stay in storage.
✅ Why LIFO is Used (Purpose):
 To issue latest-priced materials first during inflation for better cost matching.
 To protect older stock in case prices drop or for long-term holding.
 To reduce profit on paper (for tax-saving purposes in accounting).
 Useful when materials don’t deteriorate or expire over time (e.g., metals, hardware).
🏭 Real-World Example in a Raw Material Store:
 100 kg of steel rods received on Jan 1 at ₹100/kg.
 Another 100 kg received on Feb 1 at ₹120/kg.
 When production demands steel on Feb 10, LIFO issues the Feb batch (₹120/kg) first.
  The older Jan stock (₹100/kg) remains in the store.
📦 How LIFO is Implemented:
 Physically: New stock placed at the front or on top so it’s picked first.
 Systematically: ERP/WMS configured to issue newest batch number first.
 Accounting: Latest purchase price is used for calculating COGS (Cost of Goods Sold).
🧾 LIFO in Accounting (Financial View):
 In periods of rising prices, LIFO increases COGS and reduces net profit.
 It lowers taxable income because higher costs are recorded against revenue.
 But it can lead to understated inventory value on balance sheet.
⚠️Note: LIFO is not allowed under IFRS (International Financial Reporting Standards), but is still
allowed under US GAAP.
🔄 Comparison with FIFO:

Feature FIFO (First In, First Out) LIFO (Last In, First Out)

Issue Order Oldest stock issued first Newest stock issued first

Inventory Age Older items leave quickly Older items remain longer

Risk of Expiry Low High (for perishable goods)

Accounting Impact Lower COGS, higher profit Higher COGS, lower profit

Best for Perishables, time-sensitive Metals, hardware, stable goods

🚫 When NOT to Use LIFO:

 For perishable, expiring, or regulated materials (like chemicals or food).
 If you're under IFRS-compliant accounting standards.
 Where product traceability by date or batch is critical (e.g., pharma, aerospace).
Let me know if you want LIFO examples from a specific industry or how it's handled in ERP systems
like SAP or Oracle.
✅ Industries and Situations Where LIFO is used:
🏗️1. Heavy Manufacturing (Metals, Construction Materials)
 Example: Steel rods, iron bars, cement, copper coils.
 These materials don’t expire or degrade easily, so companies use LIFO to match latest cost
with production.
 Goal: Better cost control during inflation.
⚙️2. Engineering & Machinery
 Example: Nuts, bolts, bearings, fasteners, mechanical spares.
 Low risk of expiry or obsolescence, and frequent price fluctuations.
 LIFO helps cost control and tax savings in such environments.
🧾 3. Financial Accounting (Cost Management)
 Companies use LIFO in accounting (especially under US GAAP) to:
 o Increase COGS
o Lower taxable income
o Protect against rising material prices
 Used more as a financial strategy than a physical inventory method.
🧰 4. Hardware and Tool Stores
 Example: Tools, screws, pipes, PVC fittings.
 No expiry or degradation – LIFO makes sense for fast-moving items where tracking is based
on quantity, not age.
🔧 5. Oil, Gas, and Petroleum (U.S. Based)
 LIFO is sometimes used in accounting for fuel inventories due to high price volatility.
 Helps offset gains during rising prices, although physical inventory might still follow FIFO or
FEFO.
⚖️Important Conditions for Using LIFO:

Criteria LIFO Usage

Items don’t expire or spoil ✅ Yes

Prices are highly volatile ✅ Yes

Used for tax benefits (US only) ✅ Yes

Requires IFRS reporting ❌ No

Perishable or date-sensitive ❌ No

Basic FIFO Understanding Questions:

1. What is FIFO, and why is it important in store operations?

Answer:
FIFO, or First In, First Out, is a stock rotation method where the oldest materials received are issued
or used first. It's important because it ensures stock freshness, reduces expiry risks, and maintains
quality control—especially critical in raw material stores where some items may degrade over time.

2. Can you explain the difference between FIFO and LIFO? Which one is more suitable for raw
materials?
Answer:
FIFO issues the oldest stock first, while LIFO issues the newest stock first. FIFO is more suitable for
raw materials, especially those with shelf life or sensitivity to aging, as it helps prevent spoilage,
obsolescence, and ensures consistency in production quality.

3. In what types of industries is FIFO most commonly applied? Why?

Answer:
FIFO is commonly used in industries like food, pharma, chemicals, and FMCG—where materials have
expiry dates or degrade over time. It’s also used in manufacturing sectors handling temperature or
humidity-sensitive raw materials.
📦 Practical Application Questions:

4. How do you physically implement FIFO in a raw material store?

Answer:
We place the oldest materials at the front or top of racks and newer materials at the back. Bins and
pallets are labeled with GRN dates and batch numbers. Store staff are instructed to always pick from
the oldest batch first.

5. What are some challenges you’ve faced while enforcing FIFO and how did you overcome them?
Answer:
One major challenge was staff unintentionally picking newer stock due to easier accessibility. We
resolved this by reorganizing storage to support FIFO flow, improving labeling, and conducting
refresher training for store staff.

6. How do you ensure FIFO is followed during material picking and issuance?
Answer:
We use a combination of system-generated pick lists from our ERP and clear labeling with receipt
dates. Storekeepers are trained to follow the sequence strictly, and supervisors perform routine
checks during material issuance.

7. Have you ever noticed a violation of FIFO in your store? What was the impact and how did you
correct it?
Answer:
Yes, in one case, newer raw material was issued first, leading to older stock nearing expiry. We
immediately flagged it, corrected the stock balance, and implemented a bin check system and
escalation protocol to prevent recurrence.

8. How would you design a store layout to support FIFO?

Answer:
The layout must allow easy access to older stock by using flow racks or pallet lanes with “first-in”
from one side and “first-out” from the other. Clear aisle labeling, designated FIFO zones, and open
access to older stock are key.

9. What role does barcode or batch labelling play in FIFO?

Answer:
Barcode and batch labelling help track material age and ensure traceability. They allow ERP systems
to suggest the right batch and enable staff to scan and pick the oldest material accurately, reducing
human error.

10. How do you train your team to follow FIFO correctly?

Answer:
We conduct regular training sessions with practical demonstrations. Training covers SOPs, use of
labels, ERP navigation, and hands-on FIFO practice. Refresher sessions and audits reinforce the
discipline.

🔄 MOCK INTERVIEW QUESTIONS & ANSWERS – LIFO (Last In, First Out)
Basic Conceptual Questions:

1. What is LIFO and how does it differ from FIFO?

Answer:
LIFO stands for Last In, First Out, meaning the latest materials received are issued first. Unlike
FIFO (First In, First Out), LIFO keeps the oldest inventory in stock and issues the newest batches.
FIFO is suitable for perishable items, while LIFO is more suited to non-perishable raw materials
like metals or hardware where expiry isn't a concern.

2. Why do some industries use LIFO instead of FIFO?

Answer:
Industries use LIFO to match current, higher raw material costs to current production. This
provides tax advantages by reducing profit margins during inflation. It’s suitable for materials that
don’t degrade over time, like metals, tools, or plastic granules.

3. What type of materials are best suited for the LIFO method?
Answer:
LIFO is ideal for non-perishable, durable items such as:

 Steel, copper, aluminum rods

 Bolts, nuts, mechanical components
 Tools and spares These items don’t spoil, allowing older stock to be retained longer without
quality degradation.

🏭 Practical Application Questions:

4. How do you apply LIFO physically in a store layout?

Answer:
We store new material at the front or on top, so it is picked first. Storage racks are arranged to allow
access to the latest received stock. Labeling and documentation are crucial to identify most recent
batches during issuance.

5. How do you manage LIFO through ERP or WMS systems?

Answer:
Our ERP (e.g., SAP) is configured to pick materials based on latest GRN or receipt date. During
picking, it auto-suggests the latest batch. We use barcode scanning to confirm the selected batch
matches the system recommendation.

6. What challenges have you faced using LIFO in the store?

Answer:
One challenge is holding older stock too long, which may get damaged or become obsolete. To
address this, we conduct regular cycle counting and initiate slow-moving stock clearance plans.
Another issue is reconciling LIFO accounting with physical movement, especially if systems are not
aligned.

7. In a scenario with urgent material requirements, how do you ensure correct batch picking
using LIFO?
Answer:
In urgent cases, we use system-generated pick lists showing the latest stock, and cross-check it with
physical bin labels. Staff are trained to verify batch numbers, and supervisors do a second check
before final issue.

8. What are the pros and cons of using LIFO in store operations?
Answer:
 Pros Cons
Matches current costs with revenue Old stock may remain unused
Helps reduce taxable income Not allowed under IFRS
Suitable for durable items Complex physical stock handling

🧾 Accounting & Costing Questions:

9. How does LIFO affect inventory valuation and financial reporting?

Answer:
In LIFO, latest (higher) costs are charged to production, raising COGS and reducing reported
profit. This reduces tax liability. However, it also lowers closing inventory value, which may
understate company assets.

10. Is LIFO legally allowed in all countries?

Answer:
No. LIFO is permitted under US GAAP, commonly used in the USA. However, it is not allowed
under IFRS, which is followed in Europe, India, and many other countries. Therefore, companies
must comply with the respective accounting standards.

📦 Stock Control & Risk Questions:

11. What risks are associated with using LIFO in a store environment?
Answer:

 Stock obsolescence: Older stock may be forgotten or damaged.

 Space wastage: Older materials take up long-term storage.
 Mismatch in physical and system data if LIFO isn't followed correctly in ERP. To manage
this, we schedule regular stock rotation audits and report aging inventory.

12. How do you manage old stock in a LIFO environment?

Answer:
We maintain a slow-moving stock register, review it monthly, and propose either transfer to other
departments, use in non-critical applications, or write-off. Periodic physical audits ensure nothing is
deteriorating unnoticed.

📊 Operational & Strategic Questions:

13. Can LIFO impact production quality or operations?

Answer:
If older materials remain unused too long, they may become outdated or incompatible with current
specs. That’s why even in LIFO, we regularly review material age and consult production before
using older batches in special cases.

14. How does LIFO affect reordering and inventory planning?

Answer:
Since older inventory stays longer, reordering decisions must factor in true usable stock, not just
quantity on hand. We rely on age analysis reports to avoid overstocking and ensure healthy stock
turnover.

15. What actions do you take if the LIFO principle is not followed during picking?
Answer:
We review the batch movement history in ERP. If the wrong batch is issued, we raise a material
movement reversal and reissue from the correct batch. Staff involved are retrained and re-briefed to
prevent recurrence.

👨‍💼 Managerial & Store Performance Questions:

16. As a Store Manager, how do you monitor LIFO compliance in daily operations?
Answer:
I monitor ERP picking records, do random audits, and use LIFO compliance checklists. Weekly
reports show the % of issues made from the latest batch. Any deviation is investigated and corrected.

17. How do you align your store operations with LIFO and company-wide financial policies?
Answer:
We coordinate with the finance and costing department to ensure batch issues align with financial
LIFO policies. Any stock adjustment or exception is documented and approved. We also ensure store
practices reflect accounting choices.

18. Have you implemented any improvements in LIFO process during your tenure?
Answer:
Yes, I introduced batch expiry alerts, dashboard reports, and improved rack labeling to speed up
identification of latest batches. This reduced picking errors and ensured alignment with the LIFO
strategy.

19. In a system where both FIFO and LIFO are used, how do you manage material movement?
Answer:
We classify materials based on their nature: perishables go under FIFO, while non-perishables
under LIFO. The ERP is configured accordingly. Staff follow SOPs, and audits verify adherence to
the correct method for each material.

20. What KPIs would you track to ensure LIFO is working effectively?
Answer:

 Batch Age Analysis

 LIFO Picking Accuracy %
 Slow-Moving Stock %
 Material Wastage due to Age
 Stock Holding Days by Batch Age

🖥️ERP/WMS System-Based FIFO Questions:

11. How does an ERP or WMS system support FIFO? Can you give an example from your
experience?
Answer:
ERP systems like SAP or Oracle track batch numbers and receipt dates, and during picking, they auto-
suggest the oldest batch for issue. In our store, SAP generates pick lists in FIFO order, minimizing
human errors.

12. What happens if the ERP suggests an older batch but the staff picks the newer one? How do
you control such cases?
Answer:
Such mismatches are flagged during GRN or batch scanning. We implemented a check where
scanning the wrong batch shows a warning. Supervisors also verify pick slips against physical stock
before final issue.

13. How do you audit or verify that FIFO is being followed in system transactions?
Answer:
We run periodic FIFO compliance reports, compare system batch movement with physical stock, and
verify issue dates. Spot checks and monthly audits ensure alignment between ERP data and actual
stock flow.

📊 Inventory Control and Compliance Questions:

14. How does FIFO help in reducing material wastage and expiry losses?
Answer:
FIFO ensures older materials are used before they deteriorate or expire, especially in temperature-
or time-sensitive raw materials. This significantly reduces the chances of scrapping or reworking due
to expired stock.

15. What are the implications of not following FIFO in industries like food, pharma, or chemicals?
Answer:
It can lead to quality failures, production downtime, customer complaints, and regulatory non-
compliance. In pharma, for example, using expired batches can cause legal and health risks, along
with reputational damage.

16. How do you manage FIFO when dealing with bulk storage or palletized goods?
Answer:
We use flow-through racking systems and FIFO lanes, where pallets are loaded from one end and
picked from the other. Pallet tags indicate receipt date, and forklifts are trained to follow batch
order during movement.

17. How do you apply FIFO to materials that have different shelf lives or expiry dates?
Answer:
We follow a hybrid FIFO/FEFO model—materials are issued based on expiry date first, and within
that, by oldest receipt. ERP systems help flag which batch should go first, even if received later but
expires sooner.

⚖️Strategic and Managerial Questions:

18. If raw material prices are rising, how does FIFO impact your inventory valuation and cost of
production?
Answer:
FIFO results in issuing older, lower-cost stock first, so COGS is lower and reported profit appears
higher. This benefits financial reporting but may not reflect the current replacement cost, which can
impact future planning.

19. Can FIFO affect your procurement or replenishment decisions? How?

Answer:
Yes, if stock isn’t moving as per FIFO, it signals over-purchasing or slow consumption. This data helps
us adjust procurement cycles and avoid overstocking. FIFO usage also affects minimum order
quantities and reorder levels.

20. How would you handle a situation where following FIFO is not operationally feasible due to
space constraints or urgent production demand?
Answer:
In such cases, I prioritize critical materials for immediate issuance, document the deviation, and
ensure the remaining stock is handled properly afterward. I also initiate a temporary re-layout or
allocate FIFO priority zones to balance space and compliance.

📘 Perpetual Inventory

Meaning

Perpetual inventory is a system where inventory records are continuously updated in real-time
after every transaction—whether it's a receipt, issue, return, or transfer.

🎯 Objective:

To maintain real-time, accurate stock visibility through system-driven inventory updates after every
transaction.

🔁 Key Features:

 Updates instantly when material is received or issued.

 Uses ERP or WMS systems for tracking (like SAP, Oracle, etc.).
 Shows current stock levels, batch details, and value at any time.
 Allows faster decision-making for purchasing, issuing, and auditing.

🏭 Example (in a raw material store):

 Morning: 100 steel rods received → system auto-updates balance to 100.

 Afternoon: 40 rods issued to production → balance auto-updates to 60.
 All movements are traceable by GRN, material code, batch number, and timestamp.

📊 Benefits:

 Real-time visibility of inventory.

 Reduces errors and stock outs.
 Improves cycle counting accuracy.
 Essential for Just-In-Time (JIT) and LIFO/FIFO management.

📉 Difference from Periodic Inventory:

MOCK INTERVIEW QUESTIONS – PERPETUAL INVENTORY SYSTEM

🧠 1. What is a perpetual inventory system, and how does it work in a raw material store?

Answer:
A perpetual inventory system is a real-time method where inventory records are continuously
updated in the ERP or WMS after every material transaction, such as receipts, issues, or returns. In a
raw material store, when goods are received, scanned, or issued, the system immediately reflects
the updated quantity and location, allowing accurate and live tracking of stock levels at all times.

🧠 2. What are the advantages of using a perpetual inventory system over a periodic one?

Answer:
Perpetual inventory offers real-time visibility, faster decision-making, reduced stockouts, and
enhanced accuracy. Unlike periodic systems that rely on physical counts, perpetual systems help
detect variances early, support FIFO/LIFO execution, and ensure traceability of high-value or batch-
controlled raw materials—critical in an MNC environment.

🧠 3. How do you handle discrepancies in perpetual inventory?

Answer:
Discrepancies are usually identified through cycle counts or system alerts. I conduct root cause
analysis by tracing the transaction logs (GRN, issue slips, user ID, and timestamps). After approval, I
perform stock adjustments in ERP with proper documentation and reasons. I also take preventive
actions like staff re-training or bin-label correction to avoid repeat errors.

🧠 4. What kind of technology or tools are used in a perpetual inventory system?

Answer:
Key tools include ERP systems like SAP, Oracle, or Microsoft Dynamics; barcode or RFID scanners;
handheld terminals (HHT); and WMS dashboards for real-time tracking. These tools allow automated
updates and help in quick scanning of receipts, issues, and returns in a raw material store.

🧠 5. How does perpetual inventory support FIFO/LIFO implementation?

Answer:
Perpetual inventory tracks each batch with details like receipt date, quantity, and location. For FIFO,
the system auto-suggests the oldest batch during picking. For LIFO, the most recent batch is
selected. Since all movements are time-stamped, it ensures strict compliance with whichever
method the company uses.

🧠 6. What steps do you take to ensure perpetual inventory accuracy?

Answer:
I implement scheduled cycle counting based on ABC classification, ensure timely entry of all GRNs
and issues, monitor real-time dashboards, and audit bin-to-system match weekly. I also train staff on
scanning discipline and ensure proper labelling and documentation for every transaction.

🧠 7. How would you implement a perpetual inventory system from scratch in a new store?

Answer:
First, I would conduct a baseline physical count and create accurate material masters with UOMs
and storage bins. Then, I’d configure the ERP/WMS, define transaction workflows (GRN, issue, and
return), train staff, and go live with real-time scanning. I’d also set up daily reporting and cycle
counting schedules to maintain inventory accuracy from day one.

🧠 8. How do you track bin-level inventory in a perpetual system?

Answer:
Each material is linked to a bin location in the ERP. During putaway, items are scanned into a specific
bin. At any time, I can generate a bin-wise report showing the exact item, batch, quantity, and date
of storage. This allows quick picking, verification, and movement tracking.

🔎 scenario-based mock interview questions – perpetual inventory & leadership

🧠 1. Scenario: During an internal audit, the auditors find a mismatch between system stock and
physical stock for multiple critical raw materials. How would you respond as a Store Manager?

Answer:
I would first isolate the impacted SKUs and freeze further movement. Then I’d initiate a detailed root
cause analysis by comparing GRNs, issue slips, cycle count history, and ERP logs. I would check for
common factors like specific shifts, bins, or operators. Simultaneously, I’d submit a deviation report
with corrective action and update stock via approved adjustment entries. Finally, I’d implement
controls like double-checking during issues, revising SOPs, and retraining staff to prevent recurrence.

🧠 2. Scenario: Your ERP system goes down due to a server crash during peak operations. What
immediate actions do you take to ensure continuity and inventory integrity?
Answer:
In case of an ERP failure, I would immediately switch to our business continuity plan which includes:

 Notifying IT and senior management.

 Switching to manual logs and issue slips for material movement.
 Using Excel-based tracking sheets to temporarily record GRNs, issues, and returns.
 Freezing non-essential transactions.
 Once the system is restored, reconciling manual entries with ERP and posting all
transactions.
 Conducting a quick cycle count post-recovery to ensure accuracy. My priority would be
ensuring traceability and minimizing data loss.

🧠 3. Scenario: You notice a recurring shrinkage of high-value copper coils during monthly cycle
counts. How do you approach this issue from a leadership perspective?

Answer:
I would:

1. Analyze detailed variance reports across months and identify any patterns (e.g., same bin,
shift, material handler).
2. Conduct a surprise physical audit with an independent team.
3. Review CCTV footage, gate logs, and issue slips.
4. Check for system misuse—like unauthorized manual adjustments or duplicate issues.
5. Strengthen access control and bin locking mechanisms.
6. Introduce batch-level tracking and RFID tagging for high-value items.
7. Deliver a formal report to management and HR if internal theft is suspected.
8. Conduct staff re-orientation on SOPs, ethical responsibility, and penalties.

🧠 4. Scenario: You’ve just joined a plant where the last physical inventory revealed 12% stock
variance. How do you bring accuracy under control within 90 days?

Answer:
My 90-day plan would include:

 Day 1–15: Conduct baseline audit and identify top 20 items causing variance using ABC
analysis.
 Day 16–30: Freeze master data errors (UOM, locations), re-label bins, and retrain staff on
standard issue/receipt procedures.
 Day 31–60: Launch a weekly cycle counting program with daily variance dashboards.
 Day 61–90: Automate alerts for variances beyond 3%, introduce bin validation during
transactions, and create KPI targets (shrinkage <1%). Regular leadership reviews and reward-
based accountability would sustain the momentum.

🧠 5. Scenario: During an annual statutory audit, the external auditor questions the accuracy of
perpetual inventory data in your ERP. How do you defend your system?

Answer:
I’d present the evidence-based control mechanisms we have:

 Cycle count reports with physical vs ERP data.

 GRN and issue logs with scan time and operator ID.
  Audit trails from ERP showing all stock movements with timestamps.
 Exception reports showing negative inventory or duplicate entries, if any.
 System-based FIFO/LIFO issue records.
 Variance tracking with root cause and corrective actions. This proves that our perpetual
inventory system is not only real-time but also backed by process integrity and audit-ready
documentation.

🧠 6. Scenario: A particular batch of raw material shows repeated excess during cycle counts.
What could be the reason and how will you resolve it?

Answer:
This could be due to:

 Returns not recorded properly in ERP.

 Multiple bins storing the same item without linking in system.
 Wrong UOM conversion (e.g., kg vs piece). To resolve it, I would:
 Re-map all bins and check system-bin linking.
 Introduce a "One Part One Location" rule.
 Create a return register with mandatory ERP posting.
 Cross-check master data for UOM, minimum quantity, and reorder levels.

🧠 7. Scenario: The plant head asks you to prove that real-time inventory improves production
efficiency. How do you respond?

Answer:
I’d present metrics showing:

 Faster issue-to-production time (e.g., 15 mins vs 45 mins).

 Reduction in production downtime due to material non-availability.
 Real-time alerts on low stock levels triggering timely procurement.
 Less buffer stock = more space + better working capital.
 Example: Last month’s case where timely issue of epoxy resin avoided line stoppage. Data-
backed insights show that perpetual inventory supports Lean Manufacturing and smooth
production flow.

📘 Periodic Inventory
Meaning

Periodic Inventory is a system where inventory levels are updated at specific time intervals—such as weekly,
monthly, or yearly—not after every transaction. Physical counts are done to calculate stock, and all
issues/receipts are tracked manually or summarized periodically.

🔁 How It Works:

 No real-time updates after each transaction.

 Inventory is assumed to be static until the next stock-taking cycle.
 All transactions (purchase, issue, return) are recorded but not reflected in live inventory.
 Stock level = Opening Stock + Purchases - Issues (based on physical count)
🏭 Use Cases in MNC Raw Material Stores

 Backup system if ERP is down.

 Small warehouses without full ERP implementation.
 Warehouses handling slow-moving or bulk non-critical materials.
 For year-end financial closing and statutory audits.

🛠️A. PROCESS FLOW – Periodic Inventory System

1. Material Receipt

 Receive material physically and document in register or Excel.

 GRN entry made manually or at end of day/week.
 Inventory count not updated in system immediately.

2. Storage

 Material stored in bins with basic labeling.

 Location records are not always updated in real-time.

3. Material Issue

 Material issued to production.

 Issue slips or MRNs are recorded manually.
 Inventory count stays unchanged until next physical verification.

4. Periodic Physical Count

 At set intervals (e.g., end of month), physical stock count is conducted.

 Actual stock is compared to theoretical (book) stock.
 Discrepancies are reconciled through adjustment entries.

5. Stock Valuation

 Stock value is calculated at period-end.

 Usually uses methods like FIFO, LIFO, or weighted average for costing.

Step Action Owner Tool/Support

✅ Advantages:

 Simple and low-cost system.

 Suitable for small or manual environments.
 Works without full-scale ERP systems.

❌ Disadvantages:

 No real-time visibility.
 Higher chances of stock outs or overstocking.
 Inventory records may be inaccurate between counts.
 Not ideal for high-speed operations or JIT models.

📊 Example:

Scenario:

 Opening Stock (April 1): 500 kg of plastic granules

 Purchases during April: 300 kg
 Issues (estimated from production): 600 kg
 Physical stock on April 30: 220 kg
 Book stock should be: 500 + 300 - 600 = 200 kg
 Variance: +20 kg → investigate and adjust in records

🔁 📦 PERIODIC INVENTORY – PROCESS FLOW

This process follows batch-based or interval-based physical stock updates, typically monthly or quarterly,
instead of real-time tracking.

✅ Step 1: Material Receipt

 Raw materials arrive at the gate.

 Gate Entry is created manually or in a register.
 GRN (Goods Receipt Note) is prepared, but stock levels are not updated immediately in the system.
 Supporting documents: Purchase Order, Invoice, and Delivery Challan.

🔧 Stock stays in “on-hold” or “pending” status until counted later.

✅ Step 2: Storage and Tagging

 Material is moved to assigned racks or bins.

 Bins may be labeled, but bin-wise stock is not system-tracked.
 Inventory team updates Excel sheets or manual logs.

📌 Storage is physical-first; digital update is delayed until audit/count.

✅ Step 3: Material Issue to Production

 Production raises a manual Material Requisition Note (MRN).

  Store issues material using:
o Issue slip
o Gate pass
o Excel register or manual log
 Stock balance remains unchanged in ERP or ledger.

📂 Records of issues are maintained, but inventory value doesn't update until end of the period.

✅ Step 4: Returns (if any)

 Excess material returned from production.

 Documented manually.
 Stored separately until included in the next physical count.

🔄 Returns are not system-posted instantly.

✅ Step 5: Period-End Physical Stock Count

 Monthly/quarterly/year-end stocktaking scheduled.

 Inventory movement is frozen during count.
 Count is done item-wise, batch-wise, location-wise.
 Discrepancies noted between physical and book stock.

📝 Stock count sheets and tally forms used for checking.

✅ Step 6: Reconciliation & Adjustment

 Actual (physical) count compared with book stock:

o Shortage: Inventory is written off.
o Excess: Inventory is added with reasons recorded.
 Adjustments made through Stock Adjustment Vouchers or Journal Entries.
 Approvals taken from Finance, Store Manager, and Auditors.

This brings system stock in line with actual stock.

✅ Step 7: Reporting

 Final inventory valuation done using method (FIFO/LIFO/Weighted Avg.).

 Reports submitted to:
o Finance (for accounting)
o Operations (for planning)
o Management (for review)

📈 Used in P&L, balance sheet, audit reports.

MOCK INTERVIEW QUESTIONS – PERIODIC INVENTORY SYSTEM

(With real-world leadership context)

🧠 1. What is a periodic inventory system, and how is it different from a perpetual inventory
system?

Answer:
A periodic inventory system updates inventory records at specific intervals—monthly, quarterly, or
annually—through physical stock counts. Unlike a perpetual system, which updates inventory in
real-time with every transaction, periodic systems rely on physical verification and calculations like:

Ending Inventory = Opening Inventory + Purchases - Cost of Goods

Sold
this system is simpler but less precise for daily control. It is typically used in smaller or less
automated setups, or as a secondary validation method in MNC stores.

🧠 2. How would you plan and execute a periodic inventory in a raw material store?

Answer:

1. Schedule the count: Plan during low-activity periods to minimize disruption.

2. Freeze all transactions during the count window.
3. Train staff on counting procedures and assign zones.
4. Use count sheets or barcode scanners for recording.
5. Reconcile results with ERP or ledger.
6. Report variances and initiate approvals for adjustment entries.
7. Conduct root cause analysis for major gaps.

In an MNC, I ensure strict coordination with finance and production to align stock count timing and
accuracy.

🧠 3. What are the challenges of using a periodic inventory system in a high-volume raw
material store?

Answer:

 Data becomes outdated between counts.

 Greater chance of shrinkage going undetected.
 Requires operational shutdowns during full physical counts.
 Not suited for real-time replenishment decisions.
 High labor and time intensity.

That’s why I usually recommend cycle counting (hybrid) in parallel to address high-risk materials and
ensure continuous control.
🧠 4. Describe a time you handled a major variance during a periodic inventory audit.

Answer:
In one audit, we found a 9% excess in copper sheets. I investigated batch-wise receipts and found an
unrecorded return from production. The ERP entry had been missed due to a barcode scanning
failure. I corrected the data, retrained the operator, and introduced a manual return log as a backup
for all high-value items. We also added a validation step before final ERP posting.

🧠 5. What would you do if your physical stock count is less than the system quantity during
periodic inventory?

Answer:
I’d:

 Verify the count accuracy with a recount.

 Review issue slips, returns, and transfer notes.
 Check for unposted consumption or damages.
 Examine CCTV and access logs for suspicious movement.
 If justified, raise a stock adjustment entry with senior approval and submit a variance report
with reason codes. If theft or repeated errors are found, I’d escalate to audit/HR and
reinforce store access control.

🧠 6. How does periodic inventory affect financial reporting in your organization?

Answer:
Periodic inventory directly affects the Cost of Goods Sold (COGS) and closing stock figures in the
income statement and balance sheet. Accurate counts are essential during quarter-end or year-end
closing, especially in MNCs with external audits. Errors here can lead to overstated profits or
understated liabilities—so my role includes ensuring absolute accuracy and documentation to
support financial compliance.

🧠 7. In an MNC environment, would you recommend using periodic inventory as a standalone

system? Why or why not?

Answer:
Not as a standalone system. While it's essential for financial reconciliation, periodic inventory lacks
the real-time visibility needed for production and procurement planning in an MNC. I recommend
combining periodic inventory with perpetual systems and cycle counting for full control. This hybrid
approach ensures both regulatory compliance and operational efficiency.

🧠 8. How do you ensure accuracy in periodic inventory counts?

Answer:

 Conduct pre-count bin cleaning and labeling.

 Lock all inbound and outbound movements.
 Assign trained staff with clear count zones.
 Use two-level verification: counter and verifier.
 Compare with system data only after initial blind count.
 Use count sheets with lot, batch, and expiry where applicable.
  Document discrepancies and obtain sign-offs from finance/QA.

✅ Summary – When to Use

 Perpetual:
o Best for: Large-scale, fast-paced MNCs
o Benefits: Real-time control, minimal errors, supports FIFO/LIFO, lean ops
 Periodic:
o Best for: Supplementary audit check or small inventory operations
o Benefits: Simple setup, finance compliance, fewer system requirements

What is Cycle Counting?

Cycle Counting is a continuous inventory auditing technique where small subsets of inventory are
counted on a rotating schedule, instead of doing a full physical stock count at one time.

✅ Goal: Improve inventory accuracy without stopping operations.

🧭 Why is Cycle Counting Important in MNC Raw Material Stores?

 Raw materials are often high-value, high-volume, or batch-controlled.

 Supports perpetual inventory accuracy.
 Prevents costly shutdowns due to full stock audits.
 Ensures compliance, traceability, and loss prevention.

🔁 Cycle Count Process – Step by Step

✅ 1. Classify Inventory (ABC Analysis)

 A items: High-value, frequent use → counted monthly or weekly.

 B items: Medium-value → counted quarterly.
 C items: Low-value, slow-moving → counted once or twice a year.

📊 This helps prioritize the most critical inventory.

✅ 2. Prepare the Cycle Count Plan

 Create a cycle count calendar.

 Divide items by bin, item code, material group, or zone.
 Assign count frequency based on ABC classification.

🗓️Example: A-items every 30 days, B-items every 90 days, C-items every 180 days.

✅ 3. Freeze Movement for Selected Items

 Temporarily lock or flag the bins/items being counted.

 No issues, receipts, or returns allowed during counting window.

📦 Prevents mismatch due to material movement during count.

✅ 4. Conduct Physical Count

 Store staff physically counts selected items.

 Use count sheets, barcode scanners, or handheld terminals (HHT).
 Record batch number, bin location, UOM, and quantity.

🔍 Counts must be blind (no system reference) to avoid bias.

✅ 5. Compare with System Stock

 Compare physical count with ERP/WMS stock levels.

 Highlight discrepancies (shortages/excesses).
 Analyze causes: damage, misplacement, wrong posting, theft, etc.

📈 Discrepancy report is auto-generated in ERP or via Excel.

✅ 6. Reconciliation & Adjustment

 Investigate and approve corrections.

 Update system using stock adjustment entries.
 Log reason for variance (required for audits).

🛠️Adjustments must be approved by Store Manager or Inventory Controller.

✅ 7. Reporting & Root Cause Analysis

 Submit variance reports to management.

 Identify recurring issues:
o Frequent shortages in same bin?
o Scanning errors?
o Training gaps?

📑 Helps drive improvements in inventory process and SOPs.

MOCK INTERVIEW QUESTIONS & ANSWERS ON CYCLE

COUNTING
✅ 1. What is cycle counting, and why is it important in an MNC raw material store?
Answer:
Cycle counting is a method of continuously verifying inventory by counting a subset of items
regularly, instead of performing a full inventory count. It's critical in MNC raw material stores
because:

 It ensures inventory accuracy without disrupting operations.

 Helps detect errors, shrinkage, or process lapses early.
 Supports compliance, traceability, and ERP accuracy.
 Enables real-time corrective action and avoids end-of-year surprises during audits.

✅ 2. How would you design a cycle count program for a store with 10,000 SKUs?

Answer:
I’d follow the ABC classification approach:

 A items (high value / fast-moving): Counted weekly or bi-weekly.

 B items (moderate): Counted monthly.
 C items (slow-moving / low value): Counted quarterly.

Steps:

1. Categorize SKUs using Pareto analysis (80/20 rule).

2. Prepare a cycle count calendar.
3. Assign trained team members and use blind count methods.
4. Record, reconcile, and analyze variance data.
5. Generate KPI reports (accuracy %, variance %, root cause).
6. Adjust inventory and refine the process continuously.

✅ 3. What are the most common causes of discrepancies found during cycle counts?

Answer:

 Unposted or delayed material returns.

 Incorrect bin transfers.
 ERP not updated in real-time (manual lag).
 Barcode scanning errors or wrong UOM.
 Improper issue/receipt documentation.
 Internal movement without system entry.
 Theft or pilferage, especially of high-value items.

As a leader, I investigate root causes and implement corrective actions like process redesign, system
validation, and staff training.

✅ 4. How do you handle a high variance found during a cycle count of a critical item?

Answer:
Steps I follow:

1. Freeze the item/bin to avoid further movement.

2. Conduct a recount with a different person for validation.
3. Check all transaction logs, issue slips, return records, and transfer notes.
4. Compare ERP vs physical vs past count trends.
5. If theft or repeated issues are suspected, involve security and audit teams.
 6. Document findings in a variance report and raise adjustment entries with approval.
7. Implement corrective and preventive actions (CAPA) like restricted access, SOP changes,
or barcode system checks.

✅ 5. How do you measure the effectiveness of your cycle count program?

Answer:
I track the following KPIs:

 Inventory Accuracy % = (Correct count / Total items counted) × 100

 Cycle Count Compliance % = Counts done as per plan
 Variance % = (System qty - Physical qty) / System qty × 100
 Number of stock adjustments per month
 Frequency of repeat discrepancies for same SKU or bin
Regular review of these KPIs helps me fine-tune the process, retrain staff, and ensure overall
inventory control.

✅ 6. What tools or technologies do you use to support cycle counting?

Answer:

 ERP/WMS systems (SAP, Oracle, Microsoft Dynamics) for transaction history and count
tracking.
 Barcode scanners or RFID readers for quick and error-free counting.
 Excel-based dashboards for variance analysis.
 Cycle Count Scheduler tools integrated with ERP.
 Mobile apps with offline mode if network is weak in warehouse zones.

In MNCs, automation is key to reducing errors and enabling real-time decisions.

✅ 7. Can you share a real example where cycle counting helped prevent a critical issue?

Answer:
Yes, during a weekly cycle count of high-value aluminum rolls, we noticed a 12% shortfall. On
investigation, we found that:

 The rolls were returned from production but not scanned back into the ERP.
 The bin location was also wrongly assigned by a new team member.

If left uncorrected, this would have caused a production delay and a financial loss. We recovered
the rolls, updated the system, and retrained the operator. It also led to the introduction of double-
verification for returns of all critical items.

MOCK INTERVIEW QUESTIONS & ANSWERS – CYCLE COUNTING KPIs

& PROCESS IMPLEMENTATION

✅ 1. What are the key performance indicators (KPIs) you monitor for cycle counting, and why?

Answer:
I monitor the following cycle counting KPIs regularly:

 Inventory Accuracy % = (Correct counts / Total counts) × 100

 Count Compliance % = (Counts done as per plan / Scheduled counts) × 100
  Variance % = (ERP Quantity − Physical Count) / ERP Quantity × 100
 Repeat Discrepancy Rate = Number of items with recurring mismatches
 Stock Adjustment Frequency = Number of ERP adjustments made
 Root Cause Closure Rate = Discrepancy cases closed with documented action

These KPIs help ensure the reliability of stock data, reduce material loss, and strengthen audit
readiness in a raw material-heavy MNC store.

✅ 2. How do you implement a cycle counting process from scratch in a new facility?

Answer:
Here’s how I implement it step-by-step:

1. Understand inventory classification (ABC, value, criticality).

2. Design a cycle count calendar based on ABC:
o A items – weekly, B – bi-weekly/monthly, C – quarterly.
3. Allocate roles and train staff in SOPs and ERP usage.
4. Define count windows (e.g., early hours, low activity periods).
5. Use blind counts and barcode scanners to reduce bias.
6. Record and reconcile discrepancies in ERP.
7. Conduct variance analysis and document root causes.
8. Track KPIs monthly and present dashboard reports.
9. Set up review meetings with supply chain and finance.

This structured implementation ensures ongoing stock integrity without interrupting operations.

✅ 3. How do you ensure your team meets cycle count KPIs consistently?

Answer:

 I begin with clear KPI ownership and team training.

 I conduct weekly reviews of completed vs. scheduled counts.
 Assign KPIs at individual level, especially for high-value items.
 Use visual tracking (e.g., KPI dashboard in the store office).
 Recognize team members with zero variance records.
 Investigate and coach if compliance falls below 95%.
 Conduct spot audits and simulate cycle count tests.

This builds a culture of accountability and excellence.

✅ 4. What corrective actions do you take if inventory accuracy drops below 95%?

Answer:

 Root cause analysis: Was it wrong binning, posting delay, picking error?
 Conduct recounts by a second person for confirmation.
 Retrain staff on SOP violations or barcode scanning errors.
 Strengthen return and issue validation process.
 Update ERP or WMS settings if tech integration was involved.
 Escalate repeat discrepancies to cross-functional audit.

I also update the cycle count frequency for affected SKUs temporarily and monitor improvement.
✅ 5. How do you report and present cycle count performance to senior management?

Answer:
I prepare a monthly Cycle Count Dashboard with:

 Accuracy % trends (week-on-week or month-on-month)

 Top 5 high variance items and root cause summary
 Adjustment volume in units and value
 ABC classification accuracy breakdown
 Compliance vs. schedule adherence
 Corrective action status

The data is supported with charts and insights. I also include recommendations such as locking bins,
increasing frequency, or training needs.

✅ 6. How do you link cycle count performance with audit readiness?

Answer:
Strong cycle count KPIs (accuracy, variance control, compliance) create an audit-ready
environment by:

 Reducing unaccounted stock adjustments.

 Maintaining clean ledger entries.
 Ensuring traceability of discrepancies.
 Building confidence in ERP-reported stock balances.

During external audits, I share the cycle count history, reconciliation logs, and root cause reports. This
often avoids the need for full blind physical audits.

✅ 7. What role does ABC classification play in cycle counting KPIs?

Answer:
ABC classification allows strategic focus on items that matter most:

 A items (high-value): Counted more frequently, with stricter KPIs (e.g., 99%+ accuracy
expected).
 B items: Counted monthly with moderate scrutiny.
 C items: Counted less often, but still tracked.

Each category has custom KPIs, making the cycle count program resource-efficient and aligned to
risk.

Cycle Counting Case Study – Scenario-Based Question

📦 Case Background:

You are an Assistant Store Manager at an MNC manufacturing unit. Your store manages 8,000 SKUs of
raw materials. You’ve implemented a cycle counting program based on ABC classification:

 A items (critical & high value): 1,200 SKUs

 B items (moderate movement/value): 2,500 SKUs
 C items (slow-moving): 4,300 SKUs
In the last 30 days, the following cycle counting report was submitted:

Count Count Accuracy Variance Found Adjustments Made (₹

Classification
Scheduled Completed % (Units) Value)
A 480 450 93.5% 120 ₹ 6,20,000
B 200 190 96.8% 80 ₹ 1,50,000
C 100 100 98.2% 25 ₹ 45,000

🔍 Interview Questions Based on the Case:

✅ Q1. What observations can you draw from this data?

Sample Answer:

 A items are underperforming: Only 93.5% accuracy, and ₹6.2 lakh in adjustment is alarmingly
high for high-value materials.
 Compliance issue: Only 450 of 480 A item counts were completed (93.75%), indicating potential
gaps in schedule adherence.
 C items show good control, which is less critical but still positive.
 B items are in control both in terms of accuracy and financial impact.

✅ Q2. As a manager, what immediate actions would you take for A category items?

Sample Answer:

1. Conduct root cause analysis of the 120-unit variance:

o Check if misposting, wrong binning, or theft is involved.
2. Perform spot audit of other high-value A items not yet counted.
3. Increase cycle count frequency for A items (e.g., weekly instead of bi-weekly).
4. Retrain team on SOPs for receiving, issuing, and returns.
5. Implement double-verification on A item issues and returns.
6. Use ERP alerts for mismatched or late postings.

✅ Q3. How would you prevent such variances in the future?

Sample Answer:

 Barcode validation at issue/receipt to reduce human error.

 Enforce real-time ERP postings (no batch updates).
 Introduce variance tracking KPIs at staff level.
 Review and possibly redesign bin allocation for A items (one-bin-one-item principle).
 Periodically review cycle count trends and tie them into staff performance reviews.

✅ Q4. Which KPI would you prioritize in next month’s report and why?

Sample Answer:
I’d prioritize Inventory Accuracy % and Adjustment ₹ Value for A category.
Since A items are high-risk (value and impact), improvement in these KPIs directly reflects process
integrity and loss prevention.

✅ Q5. How would you present this to senior management?

Sample Answer:
I’d prepare a cycle count health dashboard including:
  KPI comparison (this month vs. last)
 Top 5 high variance SKUs with investigation status
 Root cause analysis summary (people/process/system)
 Corrective actions and expected closure timelines
 Recommendations for system automation or audit controls

Scenario 1: ERP Failure during Cycle Count

📚 Case Background:

Your team is performing the weekly cycle count for Category A items using handheld barcode
scanners connected to the ERP (SAP). Midway through the count, the ERP server crashes due to a
database issue and remains inaccessible for 6 hours. Around 60% of the counts were completed, but
none of the entries were saved.

Meanwhile, operations are ongoing — raw material issues and receipts continue manually on paper.

🧠 Mock Interview Questions & Answers:

✅ Q1. What are the immediate actions you’d take as the store manager?

Answer:

1. Pause material movements for Category A items temporarily.

2. Switch to manual documentation for all transactions (receipt/issue/transfer).
3. Secure physical storage areas to prevent unauthorized access.
4. Ask team to retain counted data on paper or handheld memory.
5. Notify IT/ERP team immediately and raise a critical priority alert.
6. Communicate the issue to production and finance to align processes.

✅ Q2. Once ERP is restored, how do you ensure data integrity and sync between system and
physical stock?

Answer:

1. Validate all manual transactions performed during downtime.

2. Re-perform cycle counting for critical A items to confirm accuracy.
3. Cross-check physical count logs with ERP stock balance post-restore.
4. Enter missed transactions with proper back-dated posting, using internal approvals.
5. Generate a discrepancy report and explain variance causes to auditors.

✅ Q3. What would be your long-term preventive actions?

Answer:

 Set up ERP offline mode/data caching for handhelds.

 Implement automated daily backups and recovery alerts.
 Conduct ERP downtime simulation drills.
 Train team on manual process SOPs.
 Collaborate with IT to segment high-risk operations into priority recovery zones.

📉 Scenario 2: Inventory Shrinkage Trend Detected

📚 Case Background:

During your monthly cycle count report, you notice an increasing trend in inventory shrinkage of
₹1.5 lakh over 3 months, particularly in non-barcoded raw materials (Category B). These include
items like greases, paints, and industrial chemicals, stored in drums and containers.

Security footage is inconclusive, and ERP shows no mismatched transactions. Most of the shrinkage
is happening from shared storage bins used by multiple operators.

🧠 Mock Interview Questions & Answers:

✅ Q1. How do you investigate this shrinkage trend?

Answer:

1. Analyse shrinkage by SKU and time period to identify patterns.

2. Review issue slips, batch consumption logs, and bin-wise movement.
3. Conduct interviews with operators handling shared bins.
4. Initiate surprise cycle counts and daily reconciliation on suspect SKUs.
5. Examine spillage, evaporation losses, or improper repackaging records.
6. Involve loss prevention team for surveillance audits.

✅ Q2. What corrective actions would you take?

Answer:

 Convert shared bins to individual operator bins with accountability.

 Start barcode tagging and serialized tracking for chemical drums.
 Limit access using RFID or bin-lock systems.
 Update SOPs to include double-verification for liquid/dense materials.
 Create a shrinkage dashboard to track per week with alert thresholds.
 Rotate staff duties to avoid repeated exposure to the same SKUs.

✅ Q3. How would you present this to higher management and prevent future occurrences?

Answer:
I’d create a Shrinkage Risk Report:

 Trend graphs of shrinkage % and ₹ value

 SKU-wise and area-wise heat maps
 Root cause categorization (process, system, people)
 Actions taken and effectiveness score
 Request for budget to implement automation, cameras, or sensors

I’d also propose a Shrinkage Prevention Program with monthly audit trails and variance-based
incentives.

ITR – Meaning in Inventory and Store Management

Definition:
Inventory Turnover Ratio (ITR) is a key performance indicator that shows how many times the
inventory is sold and replaced over a specific period, usually a year.

Formula:

Where:

 COGS = Direct cost of materials sold during the period

 Average Inventory = (Opening Inventory + Closing Inventory) / 2

✅ Purpose in Store Management:

 Measures inventory efficiency

 Identifies overstocking or understocking issues
 Supports demand planning and procurement decisions
 Helps reduce carrying costs and obsolescence

✅ Example:

If your COGS is ₹10, 00,000 and your average inventory is ₹2, 00,000:

This means inventory was turned over 5 times during the period.

✅ Interpretation:

 Higher ITR = Fast-moving stock, better cash flow, efficient inventory management
 Lower ITR = Slow-moving or excess stock, risk of aging or obsolescence

Inventory Turnover Ratio (ITR) – Benefits & Importance

✅ 1. Indicates Inventory Efficiency

 ITR shows how effectively a company is managing its stock.

 A high ratio means raw materials are moving fast, reducing waste and storage costs.

✅ 2. Optimizes Working Capital

 Faster inventory turnover means less capital is tied up in unsold stock.

 This frees up cash flow for other operational or investment needs.

✅ 3. Reduces Risk of Obsolescence

 Especially in raw materials (like chemicals, lubricants, or perishables), a high ITR ensures
materials are used before they expire or degrade.
 Helps avoid write-offs and inventory losses.
✅ 4. Improves Storage Space Utilization

 Regular movement of inventory prevents stockpiling.

 Allows better organization of store layout and reduces congestion in storage areas.

✅ 5. Enhances Procurement Planning

 ITR trends help procurement teams plan reorders based on actual consumption patterns.
 Avoids overbuying and understocking.

✅ 6. Drives Better Forecasting

 High ITR with consistent patterns allows more accurate demand forecasting.
 Improves store manager’s ability to align inventory with production schedules.

✅ 7. Improves Financial Performance

 ITR is directly linked to the Cost of Goods Sold (COGS) and gross margins.
 High turnover lowers inventory holding costs, increasing profitability.

✅ 8. Builds Audit and Management Confidence

 A strong ITR backed with data builds trust in inventory processes during internal and external
audits.
 Demonstrates that the store is well-managed and system-driven.

✅ 9. Detects Problem Areas

 Low ITR highlights slow-moving or dead stock.

 Triggers investigation into supplier issues, demand variability, or misclassified SKUs.

✅ 10. Supports KPIs for Store Teams

 ITR is often a core KPI for store managers and store assistants.
 Helps drive performance-based reviews and team accountability.

📌 Quick Real-World Example:

If your store's ITR drops from 6 to 3, it may signal:

 Over-purchasing of certain raw materials

 Drop in production/demand
 Poor material issuance tracking

This triggers deeper review of procurement planning, demand forecast, or inventory accuracy.

Mock Interview Questions on ITR (Inventory Turnover Ratio)

✅ Q1. What is Inventory Turnover Ratio and why is it important in your role?
Answer:
Inventory Turnover Ratio (ITR) measures how many times inventory is sold or used in a given period.
It’s calculated using the formula:

ITR=COGSAverage Inventory\text{ITR} = \frac{\text{COGS}}{\text{Average

Inventory}}ITR=Average InventoryCOGS

In my role, it helps track how efficiently we're managing raw material stock. A high ITR means fast
movement and lean inventory, reducing storage costs and preventing material aging or wastage —
critical in MNCs with complex supply chains.

✅ Q2. Can you explain a situation where you improved the Inventory
Turnover Ratio?

Answer:
Yes. In my previous role, I noticed our ITR for lubricants was 2.5, indicating overstocking. I analyzed
usage trends, adjusted reorder points, and implemented ABC classification for cycle counts. Within 3
months, ITR improved to 4.8. This not only reduced holding costs but also freed up storage space
and reduced expired items.

✅ Q3. What does a low ITR indicate? How would you investigate it?

Answer:
A low ITR indicates slow-moving inventory or overstocking. I would:

 Identify which SKUs have poor movement

 Review purchase patterns and demand forecasts
 Check if materials are being held unnecessarily due to production delays
 Conduct cycle counts to verify stock accuracy

This would help uncover if it’s a procurement issue, system error, or demand misalignment.

✅ Q4. How can a store manager influence the ITR positively?

Answer:
As a store manager, I can:

 Monitor real-time inventory levels via ERP

 Optimize reorder quantities using EOQ
 Implement lean storage practices
 Collaborate with procurement and production to align supply with demand
 Conduct regular ABC-based cycle counts

All these help maintain healthy ITR by keeping inventory lean and agile.

✅ Q5. What KPIs would you track along with ITR to measure inventory
health?
Answer:
Along with ITR, I would track:

 Inventory Accuracy %
 Stockout Frequency
 Inventory Days of Supply (DOS)
 Cycle Count Compliance
 Shrinkage or Adjustment Value
 Dead Stock %

Material Lot Traceability – Meaning

✅ Definition:

Material Lot Traceability refers to the ability to track and trace the history, movement, and
usage of a specific batch or lot of raw materials or finished goods throughout the supply chain —
from supplier to production to final dispatch.

It ensures visibility and control over each lot, allowing companies to know where each material
came from, how it was used, and where it went.

🧪 Key Terms:

 Lot Number (or Batch Number): A unique ID assigned to a batch of material produced or
received at the same time.
 Traceability: Ability to retrieve complete history of that lot, including origin, usage, storage,
and consumption.

🎯 Why Lot Traceability is Important:

Purpose Explanation
✅ Quality Control Allows identification of defective or contaminated lots.
✅ Recall Management Helps isolate affected batches quickly during product recalls.
✅ Regulatory Compliance Essential in pharma, food, and auto sectors for audit and documentation.
✅ Supplier Accountability Tracks defects back to vendor or production step.
✅ Inventory Accuracy Links stock levels directly to lot status (used, expired, under inspection).
✅ Expiry Management Ensures FIFO or FEFO by managing shelf life via lot tracking.

🔁 Example:

Imagine you receive 3 batches of industrial paint:

 Lot A1: Received on Jan 1, Expiry Dec 31

 Lot B2: Received on Feb 1, Expiry Jan 31
 Lot C3: Received on Mar 1, Expiry Feb 28

Using lot traceability, you:

 Issue Lot A1 first (FIFO/FEFO)

 If there’s a quality issue, you trace all items made using Lot B2
 Can block Lot B2 in ERP and alert QA for testing or quarantine

🔗 How It's Tracked:

 ERP/WMS systems (SAP, Oracle, Tally Prime, etc.)

 Barcode or QR tagging per lot
  Scanning during receiving, storage, picking, and issuance
 Lot numbers entered in BOM and GRNs

🔁 B. Process of Material Lot Traceability

Here’s the end-to-end process followed in a typical MNC store using ERP/WMS:

🧾 1. Receiving Stage

 Material received from supplier with lot number/batch code

 Details entered in Goods Receipt Note (GRN) in ERP
 Barcode or QR label generated and pasted on the material
 QA team performs inspection (if applicable)

🏷️2. Storage & Tagging

 Material stored in defined bin locations

 Lot numbers are mapped to storage bins in the system
 FIFO/FEFO system implemented through ERP alerts and bin sequencing

📦 3. Issuance to Production

 When production team raises a material requisition (MRN):

o Store issues the material based on FIFO/FEFO or work order
o Lot number used is recorded in the issuance log
 ERP captures lot number, quantity, and date of issue

🔄 4. Traceability Log Maintenance

  Every movement (receive → store → issue → consume) is recorded against lot number
 Lot-wise reports available for:
o Where used (work orders, products)
o Supplier details
o Expiry alerts or quarantine status

🚨 5. Non-Conformance or Recall

 If any issue is reported:

o Trace finished goods linked to that lot
o ERP helps block further issuance of the lot
o Store segregates the material physically
o Initiate return to supplier or quarantine procedures

🧰 6. Disposal/Expiry Handling

 ERP sends auto-alerts for upcoming lot expiries

 Store initiates inspection, extension request, or scrap disposal
 Proper documentation maintained for audit trails

🧮 Tools Used:

 ERP (SAP, Oracle, MS Dynamics, etc.)

 Barcode/RFID scanners
 Lot management reports
 Cycle count with lot-based filters

📌 Real-World Example:

A batch of lubricant oil Lot #LUBX250 has been issued to 3 work orders. Later, QA reports
contamination. With traceability:

 You identify which work orders used LUBX250

 Stop further dispatch or use
 Block the lot in ERP
 Notify procurement & raise NCR to the vendor

Example: How Lot Traceability Integrates with ERP

🔄 Use Case: Lubricant Oil Lot Integration

1. Receiving:
o Supplier sends 200L of Lubricant Oil with Lot #LUB023
o Store team scans the barcode and creates a Goods Receipt (GRN) in ERP
o ERP stores details: supplier, quantity, lot number, manufacturing & expiry date
2. Storage:
o ERP assigns bin location "BIN-A12"
o Lot #LUB023 linked to this bin; FEFO rule applies (First Expiry First Out)
3. Issuance:
o Production Work Order requires 100L of lubricant
o ERP suggests Lot #LUB023 due to earliest expiry
o Store issues material; ERP logs issuance: date, user, lot #, qty, work order ID
4. Problem:
 o Quality complaint is received for products made with this batch
o ERP traceability report shows all work orders using Lot #LUB023
o Store blocks remaining stock of LUB023 in system and segregates it physically
5. Resolution:
o QA initiates investigation
o Procurement follows up with supplier
o Rework/Recall action triggered if needed

Mock Audit Interview Q&A – Material Lot Traceability

🔍 Q1: How do you ensure material traceability in your store?

✅ Sample Answer:

"We assign a unique lot number to each batch of incoming material. This lot number is entered
during the Goods Receipt (GRN) process in our ERP system.

Each movement — receiving, storage, issuance to production — is tracked against the lot number.
Barcodes or QR codes are used for scanning, and bins are mapped to lots in the system. This creates
a complete audit trail, which we can retrieve at any time."

🔍 Q2: Can you show us how you trace a material back to its supplier or forward to finished
goods?

✅ Sample Answer:

"Yes. If you give me a lot number — for example, Lot #ALU123 — I can retrieve the supplier name,
GRN date, inspection results, storage bin, issuance details, and which production orders used it.

We use the 'Lot History Report' in our ERP, which shows both backward traceability (to supplier)
and forward traceability (to production and sales). This helps in fast recalls or audits."

🔍 Q3: What happens if a lot fails quality inspection after storage or usage?

✅ Sample Answer:

"If a lot fails inspection or is linked to a defect, we use ERP to block it from further issuance by
changing its status to 'Quarantine' or 'Rejected'.

Physically, we move the lot to a segregated area marked for Non-Conforming Materials. We also
generate a Non-Conformance Report (NCR) and inform QA and Procurement for further actions like
supplier investigation or return."

🔍 Q4: How do you implement FIFO or FEFO using traceability?

✅ Sample Answer:

"Each lot has a receipt date and expiry date in the system. Our ERP is configured to suggest lots
based on FIFO (First In, First Out) or FEFO (First Expiry, First Out), depending on the material type.
During issuance, the system restricts the user from bypassing this rule without approval. This
prevents expired or old lots from being used."

🔍 Q5: How do you handle expired or about-to-expire lots?

✅ Sample Answer:

"The ERP system generates expiry alerts for all lots nearing expiry within 30/60/90 days. These are
reviewed weekly. We either:

 Extend usage date after QC re-validation

 Issue it on priority (if safe)
 Scrap it after proper documentation

Expired lots are physically moved to a scrap/hold zone, and disposal is recorded through a Material
Write-off Note."

🔍 Q6: Have you ever conducted a mock recall using traceability? What did you learn?

✅ Sample Answer:

"Yes, we did a mock recall exercise last year. We picked a lot of critical raw material and simulated a
quality issue. Using ERP traceability reports, we were able to:

 Identify affected bins and production batches

 Stop further use
 Trace the finished goods linked to the batch
 Generate a recall report

This helped us refine our SOP and improve reaction time in case of actual recalls."

🔍 Q7: What documents or reports do you maintain for traceability audits?

✅ Sample Answer:

"We maintain the following documents/reports:

 Goods Receipt Note (GRN) with Lot details

 Quality Inspection Report linked to lot
 Bin Allocation Sheet (digital or print, linked to lot)
 Issuance History Report (lot-wise)
 Lot Movement Report (full audit trail)
 NCR and Recall Reports if applicable
All of these are traceable in our ERP and backed by physical records where required."

🎯 Advanced Material Traceability Audit Q&A – ERP, Compliance & Vendor

🔍 Q1: How is your ERP configured to support lot traceability end-to-end?

✅ Sample Answer:
"Our ERP is configured to capture lot numbers at every transaction point — including GRN, quality
check, bin allocation, issuance, and production.

It uses lot-specific master data, such as supplier code, expiry date, inspection status, and storage bin.
Reports like 'Lot Usage', 'Where-Used', and 'Expiry Management' help ensure full backward and
forward traceability, crucial for both daily operations and audits."

🔍 Q2: How do you ensure regulatory compliance (e.g., GMP, ISO, FDA) using traceability
systems?

✅ Sample Answer:

"We ensure compliance by maintaining complete digital traceability through our ERP, in line with
GMP and ISO standards.

 Every lot's movement is time-stamped and user-logged.

 QA inspection results are linked directly to the lot ID.
 Controlled access prevents unauthorized changes.
 Audit logs are stored for trace backs.

We also conduct mock recalls, system validations, and annual traceability audits to verify compliance
readiness."

🔍 Q3: What challenges have you faced with vendor-related traceability and how did you
address them?

✅ Sample Answer:

"One challenge we faced was incomplete or inconsistent lot numbers from certain suppliers. This
caused mismatches during receiving and quality inspection.

We resolved it by:

 Creating a standardized lot numbering SOP for vendors

 Training suppliers through the sourcing team
 Configuring ERP to auto-generate internal lot IDs when missing

We also implemented a vendor scorecard, where traceability compliance is a key KPI."

🔍 Q4: What actions do you take when traceability data is incomplete or missing in ERP?

✅ Sample Answer:

"If a lot is missing traceability data — such as GRN not linked to a lot or an unrecorded bin
movement — we immediately block the lot in ERP and quarantine the material physically.

Then, we:

 Initiate a root cause analysis

  Create a deviation note
 Retrain the staff if it's a human error
 Revise SOP or ERP validation logic if it's a system flaw

We also escalate critical gaps to QA or Compliance and document the corrective action in CAPA
logs."

🔍 Q5: How do you integrate supplier lot traceability with internal lot tracking during multi-tier
production?

✅ Sample Answer:

"Each raw material received from a vendor retains its original supplier lot number, which we link to
our internal lot ID in the ERP. During BOM-based production, the system records which supplier lot
was consumed against which finished goods lot.

This creates a parent-child hierarchy in the traceability chain, which we can view in 'Lot History Tree'
or 'Multi-Level Usage Reports'. This is particularly important in multi-tier assemblies or regulated
sectors."

🔍 Q6: How do you handle traceability during ERP downtime or technical failure?

✅ Sample Answer:

"We maintain a Business Continuity Plan (BCP) for ERP failures. It includes:

 Manual GRN, issuance, and storage logbooks with lot tracking

 Pre-printed barcode templates
 Offline Excel templates for critical lot records

Once the ERP is restored, all transactions are cross-verified and back-entered into the system with
proper date-time logs and approvals. We also perform a post-recovery stock reconciliation to ensure
no lot mismatches occurred."

🔍 Q7: Can you explain a situation where traceability data helped you avoid a major quality or
compliance risk?

✅ Sample Answer:

"Yes, in one instance, a batch of polymer raw material failed an after-use test in finished goods.
Using ERP traceability, we quickly identified the batch — Lot #POLY678 — and found it had been
used in only 2 work orders.

We immediately:

 Blocked the batch

 Stopped dispatches
 Notified QA and initiated product holds
Because of fast traceability, the issue was contained in less than 2 hours, avoiding a major customer
escalation and regulatory risk."

🧠 Example Interview Scenario

Q: “Can you explain how you track a critical raw material issue from store to usage point?”

A:
"Yes. For example, if we issue Lot #RM456 of aluminum to production, we track it through:

 ERP entry with lot no. and issued quantity

 Material Issue Note signed by production
 Lot is linked to work order in ERP
 We can see where the material was consumed, by date and batch

This ensures traceability and accountability at every step."

🎯 Mock Interview Q&A – Material Issue System

✅ Q1: Can you explain the material issue process in your store?

Sample Answer:

"Yes. We follow a systematic process starting with a Material Requisition Slip (MRS) raised by the
user department. After proper authorization, we check material availability in the ERP system.

Based on FIFO or FEFO rules, we generate a picking slip, pick and verify the material, and issue it with
a Material Issue Note (MIN). The ERP is updated in real-time to reflect accurate stock levels, and the
receiver signs off after confirming quantity and condition."

✅ Q2: How do you ensure correct material is issued to the right department?

Sample Answer:

"We rely on a combination of system controls and physical checks. Each requisition is tied to a
department code and user ID in ERP. Materials are picked using item codes and matched with
descriptions, quantities, and lot numbers. Barcode scanning further minimizes error, and dual
verification is done before issue. Any deviation is flagged and escalated."

✅ Q3: What are the ways materials are issued in your store?

Sample Answer:

"We issue materials in different ways:

  Planned issue: Against production orders based on the BOM.
 Requisition-based issue: On request by maintenance, QA, or admin.
 Kanban/JIT issue: For fast-moving items in lean setups.
 Kitting: Where components are grouped and issued as kits.
 Returnable issue: For reusable tools with return tracking."

✅ Q4: What KPIs do you track for the material issue process?

Sample Answer:

"Some key KPIs include:

 Issue Accuracy Rate

 Average Issue Time per Requisition
 Stock-Out Incidents
 Requisition to Issue Turnaround Time
 Lot Traceability Compliance

These KPIs help measure efficiency, accuracy, and process control in our material issue operations."

✅ Q5: How do you handle material shortages during issue?

Sample Answer:

"If there's a shortage:

 First, we communicate with the requisitioning department.

 We update ERP with a partial issue and generate a shortage report.
 If critical, we escalate to procurement and production planning.
 For recurring shortages, we analyze trends and update reorder levels to prevent future
issues."

✅ Q6: What controls are in place to prevent unauthorized material issues?

Sample Answer:

"Controls include:

 Only authorized personnel can raise and approve MRS in the ERP.
 Store staff require approval before issuing materials.
 ERP restricts access and provides audit trails for all issue activities.
 High-value or sensitive items need senior-level approval.
 Manual gate pass verification for physical movement."

✅ Q7: Can you explain how ERP helps in the material issue process?

Sample Answer:

"ERP centralizes the entire material issue workflow. It:

  Tracks real-time inventory by item, location, and batch.
 Links MRS to issue slips and work orders.
 Auto-applies FIFO/FEFO logic.
 Records lot numbers for traceability.
 Flags unauthorized or duplicate issues.

Reports and dashboards give management visibility into issue history, consumption, and trends."

✅ Q8: What challenges have you faced in material issuing, and how did you resolve them?

Sample Answer:

"We once faced frequent mismatches in issued vs. requested items. We resolved it by:

 Implementing barcode-based picking.

 Retraining staff on item master accuracy.
 Cross-checking requisition against actual work order needs.

These steps improved issue accuracy from 87% to 98% over two months."

✅ Q9: How do you ensure traceability of issued materials?

Sample Answer:

"Each issued material is tagged with:

 Lot number
 Issue date
 Work order number (if production)
 Receiver’s ID

This data is logged in ERP. We can trace back any finished product to the raw material used, which is
essential for recalls, audits, or quality issues."

✅ Q10: In an audit, how do you demonstrate material issue compliance?

Sample Answer:

"We present:

 Authorized MRS copies

 ERP reports showing issue logs by date, item, and lot
 Signed Material Issue Notes
 Lot traceability reports
 KPIs like issue accuracy, lead time

Our system ensures all issues are auditable, time-stamped, and traceable to the source."

Q: “Tell us the standard procedure you follow to issue materials from the store to the production
floor.”

Your Answer:
“The process starts when a Material Requisition Slip (MRS) is raised and approved in ERP. I verify
stock availability, pick materials using FIFO or FEFO methods, verify quantities, and issue the material
along with a Material Issue Note. The issue is posted in ERP, updating inventory in real time.”

🔹 Audit & Compliance Officer

Q: “How do you ensure traceability and prevent unauthorized material issues?”

Your Answer:
“We issue only against authorized MRS or production orders. Lot numbers are recorded at the time
of issue in ERP. The receiver signs the Issue Note, and all transactions are auditable. We also conduct
random audits and set role-based access in ERP to avoid unauthorized activity.”

🔹 Plant Head

Q: “What if a critical material is out of stock when urgently required for production?”

Your Answer:
“In such cases, we prioritize real-time coordination. I generate a shortage report from ERP, alert
procurement, and update the planning team. Meanwhile, I explore alternative lots or partial issue,
keeping the production team informed. It’s also escalated to management if it's a production
stopper.”

🔹 HR Head

Q: “Describe a real incident where you prevented a potential loss during the issue process.”

Your Answer:
“Once, an operator requested aluminum bars, but the lot he selected was expired. My team
followed FEFO and flagged it. We stopped the issue, alerted QA, and replaced it with a compliant lot.
This prevented a product quality failure and earned a QA appreciation.”

🔚 Closing Question

HR: “Any suggestions you'd bring to improve our current material issue process?”

Your Answer:
“I'd recommend integrating mobile scanners for digital issue verification, improving traceability, and
using cycle counts linked to issue frequency for real-time stock control. These steps can reduce
human error and shrinkage risk.”

📦 Scenario-Based Case Study – Material Issue Challenge

📘 Case Title:

"The Mysterious Disappearing Lots"

🧩 Background:

You are the Assistant Store Manager at a manufacturing plant producing automobile parts. Over the
last 2 weeks, production has reported multiple delays due to “missing materials.” ERP shows they
were issued, but no physical material reached the line.

🧪 Your Data (to interpret):

Date Material Code Lot No. ERP Issue Qty Physical Receipt Qty Receiver Name

Apr 1 ALM-202 A789 100 kg 0 kg Not Recorded

Apr 2 ALM-202 A790 120 kg 120 kg Kumar

Apr 3 STN-105 S001 75 kg 0 kg Not Recorded

🔍 Your Task (interview-style):

Q1: What do you think went wrong in the material issue process?
A: "It appears that ERP entries were made, but no physical issue happened. The 'receiver name' is
blank, which is a red flag. This indicates a process bypass — possibly unauthorized ERP access or
ghost transactions."

Q2: How would you investigate this issue?

A:“I’d:

1. Audit the ERP logs to check who posted the issue entries.
2. Check CCTV footage for material movement.
3. Interview staff present during the alleged issue times.
4. Review bin card entries and physical stock for discrepancies.
5. Trace if these lots were used in production or sold elsewhere.”
Q3: What corrective actions will you implement?
A:“I’d:

 Restrict ERP access for issuing material to authorized personnel only.

 Implement digital signature or biometric verification at the time of issue.
 Enforce dual verification for critical raw materials.
 Conduct weekly reconciliation of ERP vs. physical stock.”

Q4: How would you explain this situation to senior management in your review meeting?
A:
“I’d present data anomalies, highlight gaps in the issue system, and suggest process automation with
traceability solutions. I’d assure management that corrective actions are being executed with audit
support.”

📘 Case Study 2: “Vanishing Stock and the ERP Blackout”

🏭 Background Context:

You're the Store Manager in a large MNC manufacturing unit that handles high-value raw materials
such as copper, aluminum, and polymers.

Your ERP system (SAP) went down for 36 hours due to a server migration failure. During this time,
store operations were switched to manual entries using printed requisitions and physical logbooks.

Two weeks later, your monthly audit flags a shrinkage spike of 2.5%, far above the standard
tolerance of 0.3%.

📊 Data Presented in Review Meeting:

🔎 Shrinkage Pattern (Before and After ERP Downtime)

Period Opening Stock Issued Stock Closing Stock (ERP) Physical Stock Shrinkage %

March (pre-downtime) 8,000 kg 2,000 kg 6,000 kg 5,980 kg 0.33%

April (downtime + post) 7,000 kg 2,500 kg 4,500 kg 4,220 kg 2.50%

📎 Additional Observations:

 No barcode scanning was used during downtime.

 Some requisition slips have missing signatures.
 ERP reconciliation after the blackout took 3 days.
 5 items had manual entries but no corresponding digital logs once ERP was restored.
 Line supervisors complain about late or missing material.

🔍 Interview-Style Q&A Based on the Case

✅ Q1: What’s your first assessment of the cause behind the shrinkage spike?
A:"The lack of system control during the ERP downtime created a manual loophole. Material issues
happened without digital validation, and discrepancies went undetected. Missing requisition
approvals and the lack of barcode tracking likely led to both genuine mistakes and potential misuse."

✅ Q2: How would you investigate this problem?

A:"I would:

1. Cross-verify manual logbooks with actual physical stock.

2. Audit each manual MRS for signature, lot, and quantity mismatches.
3. Interview storekeepers and supervisors to identify timeline gaps.
4. Use CCTV footage during ERP blackout hours to match movement.
5. Reconstruct the inventory flow for all high-shrinkage items."

✅ Q3: What short-term actions would you take immediately?

A:"Isolate high-risk items for recount.

 Suspend material issue of items with unresolved discrepancies.

 Send a deviation report to Compliance and initiate root cause analysis.
 Manually lock impacted item codes in ERP to prevent further loss."

✅ Q4: What long-term preventive measures would you propose to avoid this in the future?

A:"I would implement:

 A business continuity SOP for ERP outages, including pre-approved manual protocols.
 Mobile ERP backup tools for material tracking.
 Mandatory offline barcode printing during downtimes.
 Require double sign-off for all manual issues.
 Audit integration with ERP, so every manual entry gets flagged post-ERP recovery."

✅ Q5: How would you explain the shrinkage issue to senior management during the audit
presentation?

A: I would present the event timeline, identify ERP downtime as the catalyst, and map all anomalies.
I’d acknowledge lapses in manual oversight and emphasize that system dependency was too high
without a fullback process. Then I’d share a corrective roadmap—both immediate and systemic.”

✅ Q6: How do you reassure stakeholders that control is back in place?

A:"I would report:

 Completion of full stock recounts
 Manual vs. ERP reconciliation logs submitted
 All discrepancies documented and under investigation
 Staff retrained on emergency manual protocols
 Weekly shrinkage audits reinstated
This builds trust that the issue is contained and improvements are underway."

🎯 Mock Interview Questions & Answers – BOM / BOQ

🔹 Q1: What is a BOM and why is it important in store operations?

Answer:
"A BOM, or Bill of Materials, is a detailed list of all raw materials, parts, and subassemblies required
to manufacture a product. In store operations, it's crucial because it guides accurate material
issuance, supports MRP in ERP systems, reduces wastage, and ensures production receives the exact
quantity of components needed."

🔹 Q2: What steps do you follow when issuing materials based on a BOM?

Answer:
"I first verify the production order in the ERP system, then refer to the BOM to identify exact items
and quantities. I use FIFO or FEFO to select the right lots, perform quantity checks, update the ERP
system with issuance, and document the transaction. The issue note is physically or digitally
acknowledged by the requester."

🔹 Q3: What’s the difference between BOM and BOQ?

Answer:
"BOM is used in manufacturing for listing materials required to assemble or build a product, focusing
on inventory and production. BOQ is used in construction or project-based environments, listing
quantities of items along with labor and costs for estimating and tendering. BOM supports material
planning; BOQ supports budgeting."

🔹 Q4: How do you handle a situation where materials issued do not match the BOM?

Answer:
"I investigate the root cause by comparing ERP records, job cards, and physical stock. I check if
alternate materials were used, if there was an error in picking, or if production substituted without
updating the BOM. Based on findings, I raise a deviation note and update the BOM if the change is
approved."

🔹 Q5: How do you ensure accuracy in BOM-related inventory management?

Answer:
"By integrating the BOM with the ERP system, enforcing real-time scanning during issue, conducting
cycle counts of high-value BOM components, and reviewing actual vs. planned usage. I also involve
QA or Engineering in reviewing BOM revisions."

🔹 Q6: Can you give an example of how BOM helped avoid a production issue?

Answer:
"Yes, once a production order was released with an outdated BOM. I cross-checked with Engineering
and noticed a material had been phased out. I flagged it before issuance, preventing a delay and
helping update the system with the latest BOM revision."

🔹 Q7: In a BOQ-driven project, how do you manage material forecasting and ordering?

Answer:
"I use the BOQ to break down required quantities per phase, cross-reference with stock levels, and
create staggered purchase requests. I monitor consumption trends to avoid overstocking and ensure
materials arrive just in time for each phase."

🔹 Q8: How do you track BOM consumption and detect variances?

Answer:
"ERP reports help me monitor issued vs. planned quantity for each BOM. Any excess usage is flagged
for investigation. I also track lot-wise consumption and check for wastage, damage, or rework that
may have caused variance."

🔹 Q9: What controls do you put in place to prevent misuse of BOM items?

Answer:
"I implement role-based ERP access, mandatory production order linkage for issuance, and enforce
digital or physical sign-off for high-value materials. I also run periodic audits and variance analysis to
detect anomalies early."

🔹 Q10: How do you handle BOM revisions in coordination with production and stores?

Answer:
"Any BOM change goes through Engineering. Once approved, I update the ERP master data and
inform the store team. I also verify that no old materials are issued post-revision and coordinate
returns or reclassification of obsolete stock."

Although only 10,000 units of the Model X were produced, ERP shows that 16,000 Lithium
Batteries were issued from the store.

📊 Inventory Snapshot:

Material Required as per BOM Issued Quantity Variance

PCB Board 10,000 10,050 +50
Copper Connectors 20,000 20,000 0
 Material Required as per BOM Issued Quantity Variance
Lithium Battery 10,000 16,000 +6,000
Screws (Type A) 40,000 40,000 0

🔍 Initial Findings:

 No additional production order was released.

 All issues were done through ERP with valid job numbers.
 Physical stock of batteries is now short by 6,000 units.
 Barcode scans were bypassed on two shift days due to device maintenance.
 Multiple store staff handled the battery issues during the week.

🔧 Your Task in the Interview or Case Study:

🎯 Q1: What are your first steps in analyzing this BOM mismatch?

Suggested Answer:

“I would:

 Review ERP logs for each issuance transaction by date and shift.
 Cross-check which operator ID performed the issue.
 Match job card numbers with actual production output.
 Interview storekeepers and check shift handover records.
 Reconcile the material movement with CCTV logs or access reports if possible.”

🎯 Q2: What possible reasons can cause this over-issuance of Lithium Batteries?

Suggested Answer:

“Potential causes include:

 Human error during manual entry due to barcode system being down.
 Issuing extra batteries for rework/replacement without proper return logging.
 System lag or double-clicking leading to duplicate ERP entries.
 Internal misuse or unaccounted consumption for other non-recorded jobs.”

🎯 Q3: How would you communicate and resolve this with other departments?

Suggested Answer:

“I’d call a joint review with Production, QA, and IT. I’d:

 Share detailed consumption vs. output analysis.

 Request QA logs for damaged/replaced units.
 Coordinate with IT to check system behavior during barcode downtime.
 If fraud or misuse is suspected, escalate to Compliance and initiate a formal audit.”

🎯 Q4: What long-term corrective actions would you propose?

Suggested Answer:
  Make barcode scanning mandatory, with no manual override without a supervisor’s
digital approval.
 Automate alerts in ERP if issued quantity exceeds BOM by >2%.
 Conduct training refreshers for store staff on BOM discipline.
 Implement a two-step approval system for high-cost items like batteries.

🎯 Q5: How would you present this case and your findings to senior leadership?

Suggested Answer:

“I’d prepare a root cause analysis (RCA) report highlighting when, where, and how the over-issuance
occurred. I'd present corrective actions already taken, preventive control recommendations, and
request leadership's support in enforcing system compliance and barcode infra upgrades.”

🧠 Bonus Panel Question:

“Let’s assume the extra 6,000 batteries were diverted for another prototype product not yet
logged in ERP. How would you handle such shadow demand cases?”

Sample Answer:

"I would suggest a dedicated R&D job code in ERP where materials can be issued separately from
production jobs. This ensures traceability, even for non-standard usage. Until then, all such requests
must be logged via manual approval with signed memos to stores."

"We’re just 5 days from an ISO audit. Why wasn’t this zone 5S compliant?"

You (Assistant Store Manager):

"This zone was under dual supervision, and during a supervisor transfer, 5S ownership became
unclear. We lacked continuity in audits and there was no follow-up on previous cleanup actions. I
take accountability and have already initiated recovery steps."

💼 Interviewer (QA Head):

"How will you fix this area in 24 hours and ensure it stays compliant?"

Your Response:

"My action plan includes:

 Sort: Launch a red-tag drive immediately for obsolete materials.

 Set in Order: Assign a two-member team to label bins and reallocate SKUs by frequency of
use.
 Shine: Deep clean the floor, racks, and fix oil leaks with Maintenance.
 Standardize: Update the rack layout and place SOP posters.
 Sustain: Assign a new 5S zone owner and restart daily 5S checklists with review."

💼 Interviewer (Auditor):

"What controls will prevent this situation from repeating after the audit?"

Your Response:

"We’ll:

 Assign permanent 5S zone owners with defined KPIs.

 Track weekly compliance in the store dashboard.
 Conduct surprise audits by cross-functional teams.
 Integrate 5S scores into team performance reviews.
 Train all new hires in 5S within the first week of joining."

💼 Interviewer (Ops Director):

"Give one metric showing 5S success and one that shows failure."

Your Response:
"A success is when picking time drops due to item accessibility — we aim to reduce it by 25%.
A failure is recurring red tags in the same zone — it shows the sustain phase isn’t working, requiring
coaching and ownership changes."

📈 Follow-Up Task:

Prepare a brief presentation for senior management titled:

“5S Revival Plan: From Non-Compliance to Excellence in 7 Days”
Include:

 Before/After Photos
 Issue-to-Action Table

🎭 Panel Mock Interview Script: 5S Case Study – “Zone C Turnaround”

👥 Panel Members:

 Plant Manager (PM) – Focuses on audit compliance and KPIs

 QA Head (QA) – Focuses on root cause and sustainability
 HR Business Partner (HR) – Focuses on team behavior and training
 Operations Director (OD) – Focuses on strategic alignment and ROI

💼 You (Candidate):

Operations Excellence / Assistant Store Manager – presenting a recovery plan for Zone C (as per the
case study)

🎤 Scene:

The audit team has identified serious 5S issues in Zone C. You’ve been called to present your
analysis, action plan, and sustainability measures.

🎬 Interview Script Begins

PM:

"Why wasn’t Zone C 5S compliant, especially so close to an ISO audit?"

You:
"Zone C faced an unexpected increase in material flow due to new product introductions.
Unfortunately, no additional capacity or supervision was assigned. The previous zone owner
transitioned out without replacement, leading to missed audits and mismanagement of SKUs. I’ve
diagnosed the problem and acted immediately."

QA:

"What were the exact 5S failures you observed?"

You:
"Here’s a breakdown:

 Sort: Obsolete materials from 2022 were still occupying active bins.
 Set in Order: No consistent labeling; some bins overloaded, some empty.
 Shine: Dust accumulation and minor oil spillage found.
 Standardize: Inconsistent rack sizes and storage formats.
 Sustain: 5S checklists hadn’t been updated for 2 months."

HR:

"How did the team react when you stepped in to make changes?"

You:
"Initially, there was resistance, especially from operators used to the old layout. I organized a 5S
refresher workshop, involved them in redesigning the rack layout, and introduced a reward system
for 5S compliance. That helped shift the mindset from enforcement to ownership."

OD:

"What’s your 5-day recovery action plan to bring Zone C back to audit-ready status?"

You:
"My action plan is:

 Day 1: Red tag campaign for obsolete stock.

 Day 2: Re-label all bins, arrange materials based on ABC and FIFO.
 Day 3: Deep clean the entire zone; assign cleaning duties per shift.
 Day 4: Standardize rack formats; place visual SOPs and item maps.
 Day 5: Run a mock 5S audit, train zone owner, and relaunch checklist cycles."

QA:

"How do you ensure this doesn’t repeat after the audit?"

You:
"I’ve created a sustainability loop:

 Assigned a permanent 5S zone owner with daily log tracking.

 Integrated weekly checklist reviews into our ERP dashboard.
  Monthly surprise cross-audits with scoring.
 Linked 5S KPIs to team performance appraisals.
 ERP triggers to auto-alert on obsolete or non-moving SKUs."

PM:

"What metrics will prove that your plan worked?"

You:
"Three clear indicators:

1. Picking time dropped from 9 mins to target 4 mins.

2. Zero wrong issue cases in the next 30 days.
3. 5S audit score increased from 55% to a minimum of 85%."

OD:

"Tie this back to overall business goals—why does 5S matter at this level?"

You:
"5S is the base of operational excellence. In Zone C, poor 5S meant shipment delays, quality risk, and
low morale. With 5S, we reduce waste, improve delivery accuracy, and create a culture of discipline
and safety—which directly supports audit compliance, customer satisfaction, and lean operations."

HR:

"If the zone owner fails again, what would your leadership approach be?"

You:
"I'd coach the owner first, identify the gap (knowledge, tools, or engagement), and offer support. If
performance doesn’t improve, I’d consider reassigning responsibilities while setting up a peer buddy
system. I believe in developing people, not just replacing them."

QA:

"Do you think digitizing 5S can help?"

You:
"Absolutely. Mobile-based audits, ERP-linked checklists, and visual dashboards can simplify tracking,
provide alerts for non-compliance, and make data actionable for daily reviews."

PM (Closing):

"You have 60 seconds. Why should we trust your plan will work?"

You (Final Pitch):

"This is more than a checklist fix — it’s a culture shift. My plan addresses layout, labeling, training,
and accountability. I’ve brought the team along, tied the results to KPIs, and ensured visibility for
leadership. Zone C is not just audit-ready — it’s future-ready."
What is Kaizen?
Kaizen is a Japanese term meaning “continuous improvement”.
It refers to small, incremental changes carried out consistently to improve processes, reduce waste,
enhance quality, and boost employee involvement.

🔧 Core Principles of Kaizen:

1. Small Changes, Big Impact – Continuous small improvements create major results.
2. Employee Involvement – Everyone from floor staff to management contributes ideas.
3. Standardize-Do-Check-Act (PDCA) – Follow a cycle to test and implement improvements.
4. Process over Results – Fix the process and the results will follow.
5. Root Cause Focus – Eliminate the root of problems, not just symptoms.
6. No Blame Culture – Encourage open discussion without fear of criticism.
7. Visual Management – Make problems and progress visible to all.

🏭 Kaizen in Store Management / Warehouse Context:

Area Kaizen Application Example

Inventory Introduce color coding for fast/slow-moving SKUs

Picking Reduce steps using better item location mapping

Material Issuing FIFO bin layout improvements to prevent expiry

Audits Suggest visual checklists with QR scan logs

Space Utilization Adjust rack heights to increase vertical storage

Error Reduction Create shadow boards for tools/materials to avoid loss

🎯 Benefits of Kaizen:

 Improves productivity & efficiency

 Boosts employee morale and engagement
 Reduces waste and non-value activities
 Enhances quality and customer satisfaction
 Builds a culture of accountability and innovation

📈 Kaizen Flow: Simple 6-Step Process

1. Identify the Problem / Opportunity

2. Analyze the Current Process
3. Generate Small Change Ideas
4. Implement the Best Idea
5. Test & Measure Results
6. Standardize the Improved Process

🛠️Kaizen Implementation Process (Store/Warehouse-Focused)

🔹 Step 1: Identify the Problem Area

 Use store metrics, ERP reports, or audit results to spot inefficiencies.

 Common areas: slow picking time, material mismatch, space utilization, overstocking,
shrinkage, etc.

Example:
Picking time in Zone B is 9 minutes per order vs. the standard of 4 minutes.

🔹 Step 2: Form a Cross-Functional Kaizen Team

 Include:
o Store executives
o Forklift operators or pickers
o Maintenance staff
o QA or Safety rep
o One Kaizen facilitator or Lean expert

Tip: Involve frontline staff who perform the daily tasks — they know the pain points best.

🔹 Step 3: Map the Current Process

 Use Value Stream Mapping (VSM) or a simple flowchart.

 Observe real-time workflows.
 Note down:
o Touch points
o Waiting times
o Backtracking
o Motion waste

Example: Picker walks extra 20 meters due to poor rack sequencing.

🔹 Step 4: Analyse and Find Root Cause

 Use tools like:

o 5 Whys
o Ishikawa (Fishbone) Diagram
o Pareto Chart

Example:

 Why is picking delayed? → because racks are randomly assigned.

 Why? → No standard layout post SKU expansion.
 Why? → No 5S re-audit done after layout change.

🔹 Step 5: Generate Kaizen Ideas

 Brainstorm low-cost, simple fixes.

 Evaluate ideas using criteria like: time to implement, cost, employee training need, ROI.
Examples:

 Color-coded bin tags by product type

 Rearranging fast-moving SKUs closer to dispatch zone
 Reprinting bin maps
 Visual SOPs near packing stations

🔹 Step 6: Implement Changes (Pilot First)

 Choose a small test area or product line.

 Assign tasks, deadlines, and owners.
 Train staff on the new setup.

Tip: Use a Kaizen Action Tracker with: | Task | Owner | Deadline | Status | Benefit |

🔹 Step 7: Measure Results

 Compare KPIs before and after:

o Picking time
o Error rate
o Distance walked
o Employee satisfaction
o Material damage %

Example:
After rack realignment and new signage, picking time improved from 9 min → 4.2 min/order.

🔹 Step 8: Standardize the Process

 Document the new workflow (SOP).

 Update ERP layout mapping if needed.
 Set daily/weekly audits to ensure consistency.

🔹 Step 9: Roll Out & Celebrate

 Scale the changes to other zones or shifts.

 Recognize team contributions (Kaizen certificate, recognition board).
 Share learnings with other departments.

🔹 Step 10: Sustain with Continuous Feedback

 Run monthly Kaizen huddles

 Create a “Kaizen Idea Box” for ongoing suggestions
 Integrate into performance reviews and team scorecards

1. Kaizen Mock Interview Questions & Answers (Store/Warehouse Context)

Q1: What is Kaizen, and how have you applied it in your previous role?

A:
Kaizen is a philosophy of continuous improvement through small, consistent changes involving
everyone. In my previous role, I led a Kaizen event in our receiving area, where we reduced
unloading time by 35% by reorganizing dock schedules and using visual flow tags.

Q2: How do you identify areas for Kaizen in a store or warehouse?

A:
I use a mix of metrics (like ITR, picking time, shrinkage), visual audits, and employee feedback. Heat
maps from ERP systems also reveal zones with the highest delays or errors—those become our
Kaizen targets.

Q3: How do you ensure team involvement in a Kaizen event?

A:
I assign cross-functional teams, host open suggestion workshops, and rotate facilitators. I also use
gamified scoreboards and recognition programs to keep morale high during and after the
implementation.

Q4: Can you give an example of a failed Kaizen and what you learned?

A:
We tried introducing barcode-based material tracking without user training. The idea was solid, but
adoption was poor. Lesson: user training and frontline involvement from Day 1 are key to Kaizen
success.

Q5: How do you track Kaizen impact?

A:
I use pre/post KPIs (picking accuracy, time, inventory variance), document it with a Kaizen log, and
display results on visual dashboards. I also conduct a 30-day post-implementation review to verify
sustainability.

2. Real-World Warehouse Kaizen Case Study

📦 Case Study: "Zone B Re-Layout to Reduce Picking Time"

Problem:
Zone B in a raw material warehouse had frequent delays in picking due to poor rack sequencing and
bin confusion. Picking time averaged 10 minutes per order.

Kaizen Action Steps:

1. Root Cause Analysis:

o Fast-moving items placed far from dispatch.
o Bins unlabelled or duplicated.
o No defined travel path for pickers.
2. Kaizen Team Formed:
o 1 Store Manager, 1 Picker, 1 QA, 1 Maintenance
3. Implemented Changes:
o Rearranged fast movers near exit
o Introduced color-coded bin tags
o Created a U-shaped walking path
o Installed directional arrows on floor
4. Result:
o Picking time reduced to 3.5 minutes
o 98% picking accuracy
o Zero rework reported in 30 days
5. Sustainability:
o Floor audits every week
o ERP-linked layout map updated
o Rewards for zone ownership

3. Mock Interview Script Based on the Above Kaizen Case Study

Panel Setup:

 QA Head, Operations Director, Store VP

🗣️QA Head:

"You claim picking time dropped by 65%. What exact changes made that possible?"

You:
We implemented a U-shaped picking path, color-coded bin tags, and rearranged fast-movers near
the dispatch area. The new layout cut unnecessary walking by 40%, and bin confusion dropped
thanks to visual cues.

🗣️Operations Director:
"How did you select which items to relocate?"

You:
We ran a 3-month ABC analysis from ERP logs. The top 20% fast movers (A-class) were relocated
within 5 meters of the dispatch dock, while C-class were placed in rear racks.

🗣️Store VP:

"What was your team structure, and how did you handle resistance?"

You:
The Kaizen team included a storekeeper, picker, QA staff, and a layout planner. Initially, there was
pushback, especially about walking patterns. I held a 30-minute kaizen launch meet, shared time-
saved benefits, and tied improvements to performance incentives.

🗣️QA Head:

"How did you ensure the improvements didn’t fade away after the event?"

You:
We implemented weekly zone audits, integrated layout into our ERP maps, and rotated zone owners
monthly to keep the energy high. Any deviation is flagged by the system and addressed the same
day.

🗣️Store VP:

"If you had to replicate this success in another zone, what would be your first 3 steps?"

You:

1. Pull zone-specific KPI data (e.g., picking errors, travel time).

2. Do a Gemba Walk to observe live challenges.
3. Build a cross-functional team and launch a Kaizen workshop with daily tracking.

Inventory –
Meaning

Inventory refers to the stock of materials, components, or finished goods that a company holds at
any given time to support its operations, production, or sales.

In a raw material store, inventory typically includes:

 Raw materials (e.g., steel, plastic pellets, chemicals)

 Packing materials
 Spare parts
 Consumables (e.g., lubricants, cleaning items)

📚 Types of Inventory in Store/Warehouse

 Type Description

Raw Material Base materials used in production

Work-in-Progress (WIP) Semi-finished goods in production line

Finished Goods Completed products ready for shipment

Maintenance, Repair & Operations (MRO) Non-production items needed to run operations

Transit Inventory Stock in transit from vendor or to customer

Buffer/Safety Stock Extra stock to prevent stockouts

🎯 Objectives of Inventory Management

 Maintain uninterrupted production & service levels

 Minimize carrying and holding costs
 Avoid stock outs and overstocking
 Track and trace all stock movements
 Ensure accurate valuation of inventory

🧰 Inventory Control Techniques

Technique Application

ABC Analysis Focus more on high-value items (A)

FIFO/LIFO Stock rotation based on movement/expiry

JIT (Just-in-Time) Reduce holding cost by receiving only as needed

EOQ (Economic Order Quantity) Optimal order quantity to minimize total cost

Cycle Counting Regular small counts instead of full audits

Perpetual Inventory Real-time inventory via ERP

Kanban / Barcode Systems Visual or tech-based stock tracking

📊 Key Inventory KPIs

KPI Description

Inventory Turnover Ratio (ITR) No. of times inventory is used or sold in a period

Stock Accuracy % Accuracy between physical vs system stock

Carrying Cost % Cost to hold inventory annually

Stockout Frequency No. of times item was unavailable when needed

Shrinkage % Loss due to theft, damage, ERP mismatch

🎤 Mock Interview Questions on Inventory

Q1: How do you classify and manage inventory in a raw material store?

A:
I classify inventory using ABC and HML analysis, and manage them via FIFO methods, barcode
traceability, and regular cycle counts. I also monitor reorder levels using ERP alerts and safety stock
settings.

Q2: What steps do you take to avoid stockouts or overstocking?

A:
I set min-max levels in ERP, review demand forecasts, track ITR, and follow up on open POs. I also
use visual boards and audit expiry dates to prevent material loss.

Q3: How do you handle inventory mismatches in ERP?

A:I investigate mismatch reasons — human error, mis-scanning, or system lag. Then I run a cycle
count, adjust records via approval process, and update SOPs or retrain staff if needed.

Q4: Explain a time you reduced inventory holding costs.

A:
We implemented JIT for packaging material and shifted bulk orders to monthly staggered lots. This
reduced average monthly holding cost by 18% and freed up 200 sq ft of space.

Q5: What technology tools do you use to manage inventory?

A:ERP systems (like SAP or Oracle), barcode scanners, handheld RFID devices, digital dashboards,
and cycle count mobile apps. These help track real-time movement, stock levels, and trigger alerts.

📦 Scenario-Based Inventory Case Study (Mock Interview Style)

🧩 Case: Inventory Shrinkage Detected

🧠 Pro Interview Tip:

“In our store, we apply ABC + FSN combo classification to prioritize fast-moving and high-value
items. We use SAP for cycle count planning, barcode scanners for issuing, and RFID for bulk stock
check. This helps us maintain 98% stock accuracy and cut shrinkage by 40%.”

🎤 Mock Interview on Inventory Method Selection (with Q&A)

👔 Position: Assistant Store Manager – Raw Material Store (MNC)

🔸 Panel Question 1:

"Which inventory control method would you apply for a fast-moving, high-value raw material?"

✅ Suggested Answer:

"I would use a combination of ABC and FSN analysis. Since the item is both high-value (A-class) and
fast-moving (F-class), I would prioritize frequent cycle counting and apply FIFO to prevent material
aging. I’d also use automated reorder levels in the ERP to avoid stockouts."

🔸 Panel Question 2:

"How would you manage non-moving, low-cost items that are cluttering the store?"

✅ Suggested Answer:
"These items fall under C-class and N-class (non-moving) in ABC-FSN. I’d recommend isolating them
in a dead stock area, checking for any cross-utilization possibility in other departments, and
proposing write-off or liquidation if unused for more than 12 months. I would also review purchasing
patterns to avoid recurrence."

🔸 Panel Question 3:

"What method do you use to reduce inventory holding cost while ensuring production doesn’t
stop?"

✅ Suggested Answer:

"I would apply the JIT (Just-in-Time) method for non-critical consumables and packaging materials,
ensuring they arrive only when needed. But for vital raw materials, I’d maintain safety stock based
on lead time and past usage. EOQ would also be used to calculate optimum order quantity."

🔸 Panel Question 4:

"When would you recommend using LIFO in the store?"

✅ Suggested Answer:

"Practically, we don’t use LIFO for material issuance due to risk of expiry or aging, especially for
perishables. However, LIFO might be applied in accounting during inflationary periods to reduce
taxable income, or in situations where newer stock must be used due to quality upgrades."

🎤 Mock Interview Questions & Model Answers

🔸 Q1: Can you explain how ABC analysis helps in store operations?

✅ Answer:“ABC analysis segments inventory by value. We give strict control to A-class items like
Titanium Dioxide due to their high cost impact. These are cycle-counted weekly, tracked closely in
ERP, and have automated reorder levels, ensuring we never face costly stockouts.”

🔸 Q2: When do you use VED instead of ABC?

✅ Answer:“VED is applied when criticality matters more than cost — like MRO or safety gear. A low-
cost spare like a temperature sensor may not be ‘A’ by value, but it’s ‘Vital’ to operations. We ensure
stock availability using VED even if the item is C-class in ABC.”

🔸 Q3: How does FSN help in inventory optimization?

✅ Answer:“FSN classifies inventory by movement. Fast-movers are closely tracked, slow-movers get
reviewed periodically, and non-movers are isolated and flagged. In our store, FSN helped us identify
₹7L worth of non-moving goods, freeing up critical space and reducing holding cost.”

🔸 Q4: How would you integrate ABC, VED, and FSN for better results?

✅ Answer:“We cross-reference ABC, VED, and FSN — for example, A+Vital+Fast items get top
priority. They’re tracked using ERP with cycle counts every week. C+Desirable+Non-moving items are
reviewed quarterly and often targeted for disposal.”

🔸 Q5: What systems or tools do you use to track these classifications?

✅ Answer:“We use SAP ERP with embedded ABC/FSN logic. Reports are generated monthly, and we
use barcode scanners for real-time tracking. For reviews, we use Power BI dashboards that show
value vs movement vs criticality overlays.”

📦 JIT – Just-In-Time Inventory System

🧠 Definition:

JIT (Just-In-Time) is an inventory management strategy where materials are received only when
needed for production, reducing inventory holding costs and waste.

✅ Goal: Deliver the right material, in the right quantity, at the right time — with zero excess
inventory.
🎯 Key Objectives of JIT:

 🧾 Eliminate waste (overproduction, waiting, storage)

 💸 Reduce carrying & holding costs
 🏭 Improve production efficiency and flow
 📊 Minimize stock levels without risking shortages
 🤝 Strengthen supplier collaboration

⚙️How JIT Works (Store Perspective):

🔄 Stage 📝 Description

Forecasting Demand-based material planning

Supplier Coordination Materials ordered only when needed

Material Receiving Small, frequent deliveries

Zero Buffer Policy No/minimal safety stock

Real-Time ERP Tracking Usage & demand data used for triggers

🏭 JIT in a Raw Material Store (Example):

Imagine you're handling packaging film for a food-grade manufacturing line.

Under JIT:

 You receive only 1 days’ worth of film stock per shift

 Delivery scheduled every morning at 6 AM
 Store keeps less than 5% safety stock
 ERP auto-generates PO based on actual consumption trends

📈 Benefits of JIT:

✅ Benefit 📌 Description

Lower Inventory Costs Less capital tied in stock

Improved Space Utilization Store layout optimized for flow

Less Obsolescence Especially important for perishable/chemical items

Increased Supplier Reliability Frequent communication and long-term partnerships

Faster Problem Detection Any disruption is immediately visible

⚠️Risks/Limitations:

⚠️Risk 💡 Mitigation

Supplier delay = production halt Build strong SLAs & backup suppliers
 ⚠️Risk 💡 Mitigation

No buffer stock for emergencies Maintain critical emergency inventory (VED items)

Needs accurate forecasting Use demand planning software with historical data

JIT Interview Questions & Model Answers

🔸 Q1: What is JIT and where would you apply it in your store?

✅ Answer:“ JIT is a lean inventory strategy where materials are procured only when required. I’d
apply it to non-critical, fast-moving items like packaging materials or cleaning supplies. It helps
reduce inventory costs and improves space utilization.”

🔸 Q2: What are the challenges of JIT and how do you manage them?

✅ Answer: “The main challenge is supply disruption. We mitigate this by ensuring strong SLAs with
vendors, GPS shipment tracking, and setting emergency stock levels in the ERP for critical items. For
weather-sensitive suppliers, we keep minimal buffer.”

🔸 Q3: Can JIT be used for critical raw materials?

✅ Answer:“ Not always. For critical or Vital (VED) items, I prefer a hybrid model — JIT with minimum
safety stock. A complete JIT model may risk production stoppage in case of delivery failure.”

🔸 Q4: How do you track JIT effectiveness?

✅ Answer: “We monitor metrics like inventory turnover ratio, order fulfilment rate, supplier OTIF
(on-time in-full), and production stoppages due to material delays. Weekly review dashboards help
us detect early issues.”

🔸 Q5: How is JIT integrated into ERP systems?

✅ Answer: “In SAP or Oracle, JIT is managed by linking material requirement planning (MRP) with
actual consumption data. Reorder triggers are automatically raised as per real-time usage. Some
vendors are linked through EDI for auto-ordering.”

Real-World JIT Case Study

📍 Company: Toyota Motor Corporation

🛠️Process: Vehicle Assembly Line

📦 Focus: JIT System for auto components like seats, engines, and electronics

✅ Success Story: Toyota – JIT Pioneer

🔧 Problem (Before JIT):

 Huge inventory buffers

  High storage costs
 Difficulty in identifying quality issues until late in production

🧠 Solution Implemented:

 Implemented JIT with:

o Daily deliveries from vendors
o Small-lot orders timed to production sequence
o “Kanban” card system for material signalling
o Close vendor partnerships with shared forecasts

📈 Results:

Impact Area Before JIT After JIT

❌ Failure Example: Toyota (COVID-19 Disruption)

🚨 Issue:

In 2020, global semiconductor shortages hit Toyota due to its lean JIT system. With no buffer stock,
production lines halted in multiple plants.

💥 Lessons Learned:

 JIT is vulnerable to global disruptions

 Some critical components need hybrid JIT + buffer
 Post-crisis: Toyota introduced “Resilient JIT” — storing minimum critical inventory for
essential parts

🎭 Mock Panel Roleplay Script: JIT Discussion

🎙️Interview Panel:

 Panellist 1 (GM-Operations)
 Panellist 2 (Head of Procurement)
 Panellist 3 (Inventory Auditor)

🎬 Scenario:

You're applying for Assistant Store Manager in an MNC electronics manufacturing company
implementing JIT.
🔹 Panellist 1: “Can you explain JIT and how you would apply it in our raw
material store?”

✅ You: “JIT means receiving materials only as needed in the production process. For example, in our
plant, I’d use JIT for PCB boards and packaging films. ERP would trigger auto-reorder based on real-
time consumption to maintain minimal stock without disrupting production.”

🔹 Panellist 2: “What if a supplier fails to deliver a JIT item on time?”

✅ You: “I’d maintain a risk matrix and classify items based on VED. For Vital components, I’d use JIT
with safety stock, or arrange dual sourcing. In ERP, we’d monitor OTIF and set vendor escalation
triggers for late deliveries.”

🔹 Panellist 3: “How would you track the effectiveness of the JIT process?”

✅ You: “We’d track KPIs like inventory turnover ratio, stock out frequency, and production delays
due to material unavailability. I’d review supplier scorecards monthly and initiate 5Why/Root Cause
Analysis if any delivery affects line stoppage.”

🔹 Panellist 1: “Have you seen a situation where JIT failed? What was the
learning?”

✅ You: “During COVID-19, we couldn’t receive connectors from China on time, and our assembly line
stalled. Post that, we moved critical items to semi-JIT with one-day buffer, and collaborated with
local suppliers for faster lead times.”

🔹 Panellist 2: “What tools or systems do you use to implement JIT?”

✅ You: “In SAP, I use real-time MRP, barcode scanning for issue tracking, and auto-replenishment
with vendor EDI links. Also, I align delivery windows with production shift timings using planning
dashboards.”

Inventory Levels:

🧠 Formulas for Inventory Level Calculations

🧾 Level 🔢 Formula

Reorder Level Reorder Level = Lead Time × Average Usage

Minimum Level = Reorder Level – (Average Usage × Average Lead Time)

Maximum Level = Reorder Level + EOQ – (Min Usage × Min Lead Time)

Average Level = (Min Level + Max Level) / 2

🏭 Real Example (Raw Material Store - MNC)

Let’s say you store plastic granules for molding machines:

 🕓 Daily usage = 500 kg

 ⏳ Lead time = 4 days
 📦 Safety stock = 300 kg
 EOQ = 2000 kg

Then:

 Reorder Level = 500 × 4 = 2000 kg

 Minimum Level = 2000 – (500 × 4) = 0 (add buffer stock here)
 Maximum Level = 2000 + 2000 – (400 × 3) = 3200 kg
 Average Level = (0 + 3200) / 2 = 1600 kg

✅ Benefits of Setting Inventory Levels

 ⛔ Avoid stock outs or overstocking

 💰 Reduces carrying costs
 🏃‍♂️Improves production flow
 🧾 Helps in budgeting and forecasting
 🔁 Automates reordering via ERP systems
🎯 Mock Interview Questions & Sample Answers

🔹 Q1: Why are inventory levels important?

✅ Answer: “Inventory levels ensure we neither overstock nor run out of raw materials. For example,
by maintaining a reorder level based on lead time, I can automate procurement and avoid line
stoppages.”

🔹 Q2: How do you calculate reorder level in your store?

✅ Answer: “I multiply the average daily usage by the lead time. If usage is 500 kg/day and lead time
is 3 days, reorder level is 1500 kg. We automate this using ERP MRP settings.”

🔹 Q3: What would you do if inventory goes below the minimum level?

✅ Answer: “That’s a danger sign. I’d immediately initiate a spot purchase or expedite the order, and
investigate why the buffer failed — whether due to forecast error or supplier delay.”

🔹 Q4: How does ERP help manage inventory levels?

✅ Answer: “ERP systems like SAP or Oracle use demand-driven MRP, which calculates real-time
reorder levels. The system auto-triggers procurement when stock hits reorder level, ensuring timely
replenishment.”

📚 Mock Case Study: Inventory Level Failure due to ERP Misconfiguration

🏭 Company: GlobalTech Components Ltd.

📍 Unit: Raw Material Store – Injection Molding Division

📦 Material: ABS Plastic Granules

🧠 ERP System: SAP S/4HANA

📊 Background Data (as configured in ERP):

Parameter Value in ERP Correct Value

Daily Consumption 600 kg/day ✅ 600 kg/day

Lead Time 4 days ✅ 4 days

Reorder Level ❌ 1000 kg ✅ 2400 kg

Minimum Level ❌ 300 kg ✅ 1200 kg

Maximum Level 4000 kg ✅ 4000 kg

Safety Stock ❌ Not set ✅ 500 kg

📉 Scenario:
You joined as the new Assistant Store Manager. On your second week, the molding line halts
production for 6 hours due to stockout of ABS granules.

Upon investigation:

 ERP shows “Sufficient stock: 1000 kg” at 9:00 AM.

 Production pulls 600 kg for 1st shift and 600 kg for 2nd shift, totaling 1200 kg.
 No reorder PO was triggered automatically.
 Stock fell to zero at 3 PM.
 Emergency local procurement was initiated at 5× regular price.

🛠️Root Cause Analysis:

🔍 Factor Findings

ERP Reorder Point Set at 1000 kg, too low vs real consumption

Safety Stock Not defined in system

Reorder Trigger Logic MRP only ran once a week (Monday), but today is Friday

Notification Settings Reorder alerts were disabled

Warehouse Staff Action Didn’t manually check reorder reports

Interview Panel Discussion Points & Answers

🔹 Q1: What went wrong in this case?

✅ You: “The reorder level was misconfigured — it should’ve been set at 2400 kg (600 × 4 days). Also,
the system lacked safety stock, and MRP wasn’t configured to run daily. The inventory dropped
below usage demand before the ERP reacted.”

🔹 Q2: What is the correct formula for reorder level in this case?

✅ You: “Reorder Level = Daily Usage × Lead Time = 600 × 4 = 2400 kg. We should also add 500 kg
safety stock to protect against demand fluctuation, making it a soft minimum of 2900 kg.”

🔹 Q3: How would you prevent this situation in future?

✅ You: “I’d:

1. Reconfigure reorder level based on actual lead time and usage.

2. Enable safety stock parameters.
3. Schedule daily MRP runs.
4. Set up automatic reorder alerts.
5. Train warehouse team to verify low-stock reports manually as backup.”

🔹 Q4: How can ERP be used to alert before such stockouts?

✅ You: “We can enable early warning triggers in SAP using safety stock breach thresholds. Also, ERP
dashboards can be configured to show materials nearing minimum level, with email alerts sent to
store and procurement heads.”

🔹 Q5: If a critical material keeps running out, but system settings are correct, what else could
cause it?

✅ You: “Other reasons might be:

 Supplier delays
 Higher-than-forecast consumption
 Manual issuance errors (wrong batch issued)
 ERP sync issues between physical and system stock I’d perform a variance report and cross-
check batch consumption vs issued quantity.”

💼 Mock Panel Interview Script: Inventory Level Implementation Challenge

🎯 Context:

You’ve recently joined InduGlobal Polymers Ltd., which uses SAP S/4HANA. Their raw material store
handles 2,000+ SKUs of chemicals, additives, and packaging materials. They've been facing frequent
stockouts of fast-moving SKUs and overstocking of slow movers, increasing holding cost by 15% YoY.

💼 Panelist 1:

"We’ve had recurring issues with stockouts for our core additives, despite ERP showing stock.
What’s your approach to fixing this problem through Min, Max, and Reorder level configuration?"

✅ Your Answer:

“First, I’ll initiate a material-level consumption analysis, preferably over the past 6 months. Based on
that, I’d:

 Calculate daily average usage.

 Match it with actual supplier lead time.
 Define accurate Reorder Level = Daily Usage × Lead Time.
 Then I’d add Safety Stock based on variability trends.
 Minimum Level = Reorder – (Usage × Min LT), and Max Level based on EOQ logic. Finally, I’ll
configure these in the ERP material master and test it on 10 critical SKUs.”

💼 Panelist 2 (ERP Head):

"Our ERP team says reorder levels are already configured. So why are we still facing shortages?"

✅ Your Answer:
“In my experience, problems persist due to:

1. Static reorder levels not updated after consumption trends change.

2. MRP jobs not scheduled daily — I've seen them run weekly.
3. Alerts not reaching the right users or disabled.
4. Safety stock not configured for high variability SKUs. I’d audit current ERP configs and
compare system reorder vs actual trigger levels using consumption data.”

💼 Panelist 3 (Ops Director):

"You’re tasked with implementing min/max levels across 2,000 items in 30 days. What’s your
execution plan?"

✅ Your Answer:

“I’d break it into phases:

 Phase 1 (Days 1–7): Identify top 20% high-value and high-usage items (ABC/FSN).
 Phase 2 (Days 8–15): Run consumption reports and lead time data. Use Excel formulas to
calculate Min/Max/Reorder levels.
 Phase 3 (Days 16–20): Configure levels in ERP, set MRP daily, enable alerts.
 Phase 4 (Days 21–30): Monitor PO triggers, stock flow, issue adjustments, and train staff to
respond to ERP alerts manually too. I’ll also create SOPs and review logic every quarter.”

💼 Panelist 1 (Follow-up):

"What if your reorder point is correct, but the material still goes out of stock?"

✅ Your Answer:

“Then I’d check:

 Whether actual demand exceeded forecast (sudden batch run).

 If manual issue entries are updated late in ERP (system mismatch).
 Whether the PO triggered but procurement delay occurred.
 Or if stock was issued under the wrong material code. I’d coordinate with production and
procurement to sync data, and set up exception alerts in the ERP.”

💼 Panelist 2:

"How do you measure success after implementing Min/Max/Reorder controls?"

✅ Your Answer: “I’d track:

 Stockout frequency per SKU (goal: <5% for A-class items).

 Inventory turnover ratio improvement.
 ERP reorder triggers vs. manual interventions.
 Holding cost trend post-implementation.
 Internal audit findings on reorder accuracy. I’ll present this as a dashboard to management.”

│ Safety + │ ← 3200 kg (Reorder)
│ Reorder │
├────────────┤
│ Min Level │ ← 1600 kg
├────────────┤
│ Stockout │ ← 0 kg
└────────────┘

💼 Question 1:

What is the purpose of maintaining Min, Max, and Reorder levels in inventory?

✅ Answer:
The purpose is to maintain an optimal stock level that avoids both overstocking and stockouts.

 Min Level ensures safety against unexpected demand.

 Reorder Level acts as a trigger point to initiate replenishment.
 Max Level prevents excessive inventory buildup, reducing holding costs.
This balance improves service level, reduces lead time risks, and enhances supply chain
efficiency.

💼 Question 2:

How do you calculate Reorder Level?

✅ Answer:
Reorder Level = Average Daily Usage × Average Lead Time

For example, if daily consumption is 200 units and the lead time is 5 days:
Reorder Level = 200 × 5 = 1,000 units

This means a new order should be placed when stock falls to 1,000 units.

💼 Question 3:

What actions will you take if stock outs still happen even after setting reorder levels?

✅ Answer:
I will perform a root cause analysis:

 Check if the lead time has increased unexpectedly.

 Analyze if daily usage has spiked suddenly.
  Verify if MRP or auto-PO triggers are delayed in ERP.
 Audit manual stock adjustments not reflected in the system. Corrective actions would
include updating lead times, safety stock, or reorder points, and coordinating with
procurement for faster replenishment.

💼 Question 4:

How do you determine the Maximum Level?

✅ Answer:
Max Level = Reorder Level + EOQ – (Minimum Daily Usage × Minimum Lead Time)

It’s the highest stock a store should hold post-receipt. It considers replenishment cycles and ensures
space and cost efficiency by not exceeding storage capacity or capital allocation.

💼 Question 5:

What challenges do you face when implementing Min/Max levels in an ERP system?

✅ Answer:

 Static levels not updating as consumption trends change.

 Wrong categorization of materials (fast/slow moving).
 Lead time variability not captured accurately.
 Lack of auto-alerts for reorder point triggers.
 Users overriding ERP triggers manually. To overcome these, I recommend quarterly reviews,
continuous master data updates, and ERP validation rules with role-based access.

💼 Question 6:

How does Min/Max level configuration affect procurement?

✅ Answer:
It drives proactive procurement planning:

 ERP generates PRs or POs automatically when stock hits Reorder Level.
 It avoids last-minute urgent purchases.
 Ensures steady material flow aligned with production needs.
 Helps buyers prioritize orders based on stock criticality.

💼 Question 7:

Have you faced a situation where incorrect Min/Max levels caused issues? What did you do?

✅ Answer:
Yes, in my previous role, Max Level for a slow-moving item was set too high. It led to excess stock,
expired materials, and high holding costs.
I corrected it by analysing the FSN (Fast/Slow/Non-Moving) classification, reduced Max Level, and
implemented review alerts every quarter to adjust for seasonality.
💼 Question 8:

How do you align Min/Max/Reorder levels with ABC classification?

✅ Answer:
I give priority to:

 A-class items: Frequent reviews, tighter Min/Max levels, and safety stock.
 B-class: Moderate control and periodic review.
 C-class: Basic levels, bulk ordering, less frequent updates.
This way, control is optimized based on value and risk.

💼 Question 9:

What tools do you use to monitor the effectiveness of Min/Max levels?

✅ Answer:

 ERP dashboards (e.g., SAP MM, Oracle) showing reorder triggers.

 Cycle count reports for stockouts and overstocks.
 Inventory Turnover Ratio to evaluate movement.
 Alerts on critical stock depletion.
 Monthly variance analysis reports to track deviation between system and actual.

💼 Question 10:

How do you ensure Min/Max levels are updated regularly?

✅ Answer:
By implementing a standard operating procedure (SOP) that mandates:

 Monthly review of fast-moving SKUs.

 Quarterly reviews for slow/non-moving items.
 ERP data extraction for consumption and lead time trends.
 Approval flow before changes in master data. This ensures dynamic control adapting to real-
world changes.

Absolutely! Here's a clear and simple breakdown of how to calculate Minimum Level, Maximum
Level, and Reorder Level — with full formulas, sample data, and step-by-step calculations for each.

1. Reorder Level (ROL)

📘 Formula:
Reorder Level = Average Daily Usage × Average Lead Time

📊 Example:

 Average Daily Usage = 200 units

 Lead Time = 5 days

✅ Calculation:

Reorder Level = 200 × 5 = 1,000 units

📌 Meaning:
When stock reaches 1,000 units, you should trigger a new purchase order.

2. Minimum Level (Min Stock)

📘 Formula:

Minimum Level = Reorder Level – (Average Usage × Average Delivery

Time)

📊 Example:

 Reorder Level = 1,000 units

 Average Usage = 200 units/day
 Average Delivery Time = 2 days

✅ Calculation:

Minimum Level = 1,000 – (200 × 2) = 1,000 – 400 = 600 units

📌 Meaning:
You should never let stock fall below 600 units to avoid risk of stock out during lead time.

3. Maximum Level (Max Stock)

📘 Formula:

Maximum Level = Reorder Level + Economic Order Quantity – (Minimum

Usage × Minimum Lead Time)

📊 Example:

 Reorder Level = 1,000 units

 EOQ (Economic Order Quantity) = 1,500 units
 Minimum Usage = 150 units/day
 Minimum Lead Time = 3 days

✅ Calculation:

Maximum Level = 1,000 + 1,500 – (150 × 3)

 = 2,500 – 450 = 2,050 units

📌 Meaning:
You should never stock more than 2,050 units to avoid overstocking and storage cost increase.

🧮 Summary Table:

Inventory Parameter Formula Result (Units)

Reorder Level Avg. Daily Usage × Avg. Lead Time 200 × 5 = 1,000

Minimum Level ROL – (Avg Usage × Avg Delivery Time) 1,000 – 400 = 600

Maximum Level ROL + EOQ – (Min Usage × Min Lead Time) 2,500 – 450 = 2,050

Reorder Level = Average Daily Usage × Average Lead Time

For example, if daily usage is 200 units and lead time is 5 days, then:
ROL = 200 × 5 = 1,000 units

I set this in the ERP so that when stock hits 1,000, a replenishment alert is generated automatically.

🎙️Ms. Rina:
"What’s the significance of maintaining Minimum and Maximum stock levels?"

🧑‍💼 Candidate (You):

These levels ensure inventory stays within optimal limits.

 Minimum Level = ROL – (Average Usage × Delivery Time)

Example: If ROL is 1,000, average usage is 200, and delivery time is 2 days:
Min = 1,000 – (200 × 2) = 600 units
 Maximum Level = ROL + EOQ – (Min Usage × Min Lead Time)
If EOQ is 1,500, Min usage is 150, and Min lead time is 3 days:
Max = 1,000 + 1,500 – (150 × 3) = 2,050 units

This avoids overstocking and understocking, especially for high-value raw materials.

🎙️Mr. Roy:

"What challenges have you faced while implementing these levels in ERP, and how did you solve
them?"

🧑‍💼 Candidate (You):

In one case, the system had static reorder points not aligned with real-time consumption. Also, lead
time wasn’t updated, leading to delayed POs.

I resolved it by:

 Conducting consumption trend analysis.

 Updating lead times based on supplier performance.
 Collaborating with IT to automate dynamic reorder triggers.
 Training staff on maintaining accurate MRP parameters.

🎙️Ms. Rina:

"Have you used ABC or FSN analysis to influence Min/Max levels?"

🧑‍💼 Candidate (You):

Yes. For A-category, Fast-moving items, I keep tighter Min/Max levels and review them monthly.
For C-category, Slow/Non-moving items, I set higher Max to accommodate bulk procurement and
review less frequently.
This prioritizes inventory control based on criticality and consumption behavior.

🎙️Mr. Sharma:

"Let’s say stockouts are still occurring despite Min/Max levels. What would be your action plan?"

🧑‍💼 Candidate (You):

I would:

1. Analyze if the lead time has changed.

2. Check if demand has increased unexpectedly.
 3. Look for ERP trigger delays or approval bottlenecks.
4. Conduct a cycle count to validate physical vs system stock.

Then, I’d revise reorder points, possibly add safety stock, and coordinate a rapid PO to avoid
production delays.

🎙️Mr. Roy:

"How do you audit the accuracy of Min, Max, and Reorder configurations?"

🧑‍💼 Candidate (You):

I run monthly variance reports between:

 Planned vs Actual consumption.

 ERP-triggered PRs vs Manual PRs.
 Delays in order placement vs expected timelines.

I also coordinate quarterly master data reviews with the planning team to ensure the configurations
align with seasonality and production schedules.

✅ End of Script – Panel Comments:

Mr. Sharma:
"Impressive control of theoretical and real-time application."

Ms. Rina:
"You’ve clearly worked with dynamic environments and real ERP constraints."

Mr. Roy:
"Your system validation and process ownership are noteworthy."

💼 Mock Interview: Automated Stock Sheets

❓ Q1: What are automated stock sheets and why are they important in a warehouse/store
environment?

✅ A1: Automated stock sheets are digital tools—usually Excel or Google Sheets—used to manage
inventory with built-in formulas and auto-update mechanisms. They're important because they
reduce manual errors, enable real-time visibility of stock levels, trigger reorder alerts, and improve
overall inventory control. This is especially critical in raw material handling, where stock accuracy
affects production schedules and procurement planning.

❓ Q2: How do you ensure data accuracy in an automated stock sheet?

✅ A2: I use dropdown menus to prevent manual entry errors, protect cells with formulas, and
maintain separate logs for receipts and issues with timestamps. I also implement regular cycle
counts and reconciliations, comparing physical stock with system data to ensure consistency. In
addition, if ERP is used, I validate the data sync weekly.
❓ Q3: What KPIs can you track using automated stock sheets?

✅ A3: Key KPIs include:

 Inventory Turnover Ratio (ITR)

 Stock Availability (%)
 Cycle Count Accuracy
 Stockout Frequency
 Slow/Non-Moving Items
 Reorder Fulfillment Rate These metrics help drive better inventory decisions and audit
readiness.

❓ Q4: Describe a situation where automated stock sheets helped avoid a major issue.

✅ A4: At my previous job, the automated stock sheet alerted us when a high-volume raw material
dropped below the reorder level. The ERP reorder hadn’t triggered due to a configuration glitch, but
because the sheet flagged it visually, we manually ordered the material just in time to avoid a
production halt. This early alert prevented a delay and saved the company from a penalty.

❓ Q5: What challenges can arise while using automated stock sheets, and how do you solve
them?

✅ A5: Common challenges include formula errors, unauthorized edits, or outdated entries. I mitigate
these by locking formula cells, setting user-level permissions, and conducting daily validations. For
large teams, I also set up cloud-based versions so multiple users can update stock in real time with
version control.

❓ Q6: How do you integrate automated stock sheets with an ERP system?

✅ A6: I use export-import functionalities between ERP and Excel. For example, we export daily GRNs
and material issues from ERP and import them into the stock sheet using lookup formulas. In
advanced setups, we can also use APIs or middleware tools for live sync. This dual-tracking ensures
accuracy, especially in case of ERP delays or failures.

❓ Q7: How would you train your store team to maintain automated stock sheets effectively?

✅ A7: I conduct hands-on training on data entry, explain the logic behind formulas, and share SOPs
for each transaction type (receipt, issue, return, adjustment). I also introduce a checklist for daily
closing, and assign roles like “data entry,” “checker,” and “approver” to maintain discipline and
accountability.

Full Kitting – Meaning

Full Kitting is a process in stores or production planning where all the materials required for a
specific job, batch, or order are collected, verified, and grouped together before they are issued to
production or assembly lines.

Think of it like preparing a complete meal kit — everything from ingredients to tools is gathered
before cooking begins.
🏭 Where It’s Used

 Manufacturing and assembly lines

 Raw material stores (for pre-staging materials)
 Project-based production (automotive, electronics, aerospace, FMCG)
 MNCs using lean practices, JIT, or batch manufacturing

🔄 Full Kitting Process

Step Description

1️⃣ Production Request Raised – Based on BOM (Bill of Materials) or work order

2️⃣ Kitting List Generated – All parts, materials, quantities listed

3️⃣ Material Picking – Store team picks each item from stock

4️⃣ Verification – Checked against kitting list (manual or via barcode scan)

5️⃣ Bundling/Packaging – Items are grouped as one "kit" per job/batch

6️⃣ Labeling & Dispatch – Labeled with job/order number, sent to shop floor

7️⃣ Handover/Consumption – Issued to production team just-in-time

🎯 Benefits of Full Kitting

Benefit Why it Matters

✅ No Line Stoppage Ensures all parts are ready before production starts

✅ Reduces Delays No missing parts mid-process

✅ Streamlines Workflow Improves coordination between store and production

✅ Improves Inventory Accuracy Exact quantity tracking

✅ Supports JIT & Lean Avoids waste, buffers, and overproduction

✅ Improves Traceability Kit has batch/lot information, expiry, and origin

✅ Simplifies Audits Full kit tracking makes variance investigation easier

💼 Real-Life Example (MNC Raw Material Store)

A large auto parts manufacturer produces engine assemblies. Each engine needs 12 components
from different racks, each with different suppliers, lots, and lead times.

Without full kitting, operators often started assembly only to find 1–2 parts missing, causing
downtime. After full kitting was implemented:

 Kits were prepared one day before production

  Items were scanned and pre-labeled
 Downtime due to material shortage dropped by 95%

Mock Interview Question and answers

1. What is full kitting, and why is it important in store operations?

✅ Answer: Full kitting is the process of gathering and verifying all required materials listed in the Bill
of Materials (BOM) for a specific production order or job and assembling them into a single,
complete package before issuing it to the production team.
It's important because it ensures that production runs smoothly without interruptions due to
missing materials, improves efficiency, supports lean and JIT principles, and enhances material
traceability and inventory accuracy.

❓ 2. How do you ensure that a kit is 100% accurate before issuing to production?

✅ Answer: I follow a strict 3-step verification process:

1. Pick items directly from the BOM list using barcodes or item codes.
2. Cross-check quantities and specifications manually or with handheld scanners.
3. Supervisory validation: A second-level checker confirms kit contents before it’s sealed and
labeled.

Additionally, we use checklists and digital verification within the ERP system to prevent errors and
ensure kit accuracy.

❓ 3. How does full kitting help reduce material wastage or delays?

✅ Answer: Full kitting reduces wastage by issuing only the exact quantity required for a production
job. It minimizes over-picking, double handling, and unnecessary storage movements.
It also prevents delays by ensuring that all components are available upfront, so production doesn’t
halt due to missing or late-arriving materials. This leads to better planning, smooth workflow, and
reduced emergency procurement.

❓ 4. Explain a time when full kitting helped avoid production loss.

✅ Answer: At my previous company, we received a short-notice production change request. The line
was about to switch to a high-priority product run. Because we had a full kitting system in place, my
team quickly generated a kitting list, picked all items from inventory, and verified them within 90
minutes.
Without full kitting, the line would have faced a 4-hour delay due to uncoordinated material
availability. This process saved both time and cost, and production started on schedule.

❓ 5. What ERP features do you use to support the kitting process?

✅ Answer: We use ERP features such as:

 Work Order BOM explosion to generate kitting lists

 Material Reservation and Allocation tools to pre-block stock for kits
  Barcode Integration for scanning during picking
 Batch/Lot tracking to maintain traceability
 Shortage reports and alerts to detect missing components early These features make the
kitting process systematic, faster, and compliant.

❓ 6. How would you handle missing items during kitting preparation?

✅ Answer: If an item is missing, I first:

1. Check alternate stock across locations or substitute items if BOM permits.

2. Raise internal alerts to procurement or planning if stock is genuinely unavailable.
3. Update ERP with exception remarks so production is informed about the pending items. If
critical, I would also explore inter-department stock transfers or partial kit release
depending on urgency.

❓ 7. How do you control batch traceability and lot expiry within kits?

✅ Answer: We record batch numbers, lot IDs, and expiry dates in the kitting log, and link them to
the work order in the ERP.
Each kit has a label showing all batch details, so if any issue arises during production or customer
complaints, we can trace it back to the exact kit and supplier.
Also, we use FIFO or FEFO during kit preparation to ensure that older stock is consumed first,
avoiding expiry-related losses.

Would you like this turned into:

 A panel roleplay script where you're interviewed by senior leaders?

 A real-world case study based on a kitting failure or success?
 Or a visual flowchart to explain this in an interview presentation?

🧾 What Are Automated Stock Sheets?

Automated Stock Sheets are digitally managed spreadsheets or ERP-integrated tools that track
inventory levels in real-time or at regular intervals without the need for manual data entry.
They replace traditional pen-paper or Excel-based stock tracking and help maintain accurate stock
balances, transactions, and trends — automatically.

⚙️How Automated Stock Sheets Work – Step-by-Step

🔢 Step 💡 Description

1. Data Source The system connects with ERP, barcode scanners, POS, or procurement
Integration modules to pull data like: GRN, stock received, issues, returns, adjustments.

2. Stock Movement Every movement (inward, outward, transfer, return, write-off) is automatically
Recording recorded in the sheet — without manual entry.

3. Formula-Driven The sheet uses pre-set formulas (like Opening Stock + Inward - Outward) to
Logic keep balances updated per item/SKU.

4. Alerts and Reorder points, minimum stock alerts, stock-outs, or excess stock are flagged
 🔢 Step 💡 Description

Highlights automatically.

5. Real-Time Dashboards and sheets reflect live stock status by item, batch, location, or
Reporting category.

6. Audit & Lock Certain cells are locked for editing. Changes are tracked using timestamps,
Features user IDs, or change logs.

7. Backup & Version Cloud-based sheets (e.g., Google Sheets with Apps Script or Excel + Power
Control Automate) have backup and history logs for audit compliance.

📦 Example: Stock Sheet Entry Logic

Item Code Description Opening Stock Inward (GRN) Outward (Issue) Adjustment Closing Stock

RM-101 Copper Wire 100 50 80 -2 68

The sheet calculates 100 + 50 - 80 - 2 = 68 automatically after each transaction is synced

or entered.

🔌 Tools Commonly Used

 ERP integration (SAP, Oracle, Zoho, NetSuite)

 Google Sheets + App Script (for mid-level automation)
 Excel + Power Query/Power Automate

🎯 Why It’s Important for Store Managers

 Saves time and errors from manual updates

 Improves stock visibility for planning and audits
 Allows real-time decisions for procurement and replenishment
  Supports cycle counting, FIFO, expiry control

✅ Mock Interview Q&A: Automated Stock Sheets

❓Q1. What are automated stock sheets, and how do they improve inventory accuracy?

✅ Answer: Automated stock sheets are digital tools or ERP-driven spreadsheets that track inventory
movements without manual updates. They auto-calculate stock balances based on real-time inputs
like goods receipts, issues, returns, or adjustments.
They improve accuracy by eliminating manual errors, ensuring real-time visibility, and integrating
alerts for stockouts, reorder levels, or overstocking.

❓Q2. What systems or tools have you used to implement automated stock tracking?

✅ Answer: I’ve worked with SAP and Zoho Inventory, where automated stock updates occur through
integrated GRN and issue modules.
In smaller environments, I’ve implemented Google Sheets + App Script and Excel with Power Query,
linking them to barcode scanning data and auto-refreshing dashboards.

❓Q3. How do automated stock sheets reduce shrinkage and overstocking?

✅ Answer: They reduce shrinkage by enabling tighter control through real-time tracking, usage logs,
and alerts on negative stock or unrecorded movements.
Overstocking is avoided with auto-calculated reorder levels, usage trends, and visibility into slow-
moving inventory — so procurement is more accurate.

❓Q4. Can you explain how formula-driven logic works in automated stock sheets?

✅ Answer: Yes. The formula used is generally:

Closing Stock = Opening Stock + Receipts - Issues ± Adjustments
These are auto-calculated row by row using dynamic data feeds or lookups from ERP/inputs. The
system can be configured to update instantly when a new transaction is recorded.

❓Q5. How do you ensure security and integrity of these sheets?

✅ Answer: We use access-controlled sheets (with user roles), version control, and change logs to
track edits. In ERP, user-level transaction rights prevent unauthorized stock movement.
We also back up sheets daily and lock formula cells so users can’t manipulate critical data.

❓Q6. Share a real example where automated sheets helped in an audit or saved effort.

✅ Answer: During a stock audit, our automated sheet flagged a variance of 50 units in high-value raw
material. Because each transaction was logged with GRN and issue details, we traced the issue to a
missed return entry.
It saved hours of manual checking and helped us avoid a false discrepancy report.

🏢 Case Study: Automation Reduced Shrinkage and Saved Time

💼 MOCK INTERVIEW – Inventory Control System

🎙️Panel: Store Director | Operations Head | Supply Chain Auditor

❓ Q1: What is inventory control and why is it important in a raw material store?

✅ Answer:
Inventory control is the process of monitoring and managing stock levels to ensure that the right
quantity of materials is available at the right time without overstocking or stockouts. In a raw
material store, this is vital to avoid production delays, minimize carrying costs, prevent expiry losses,
and ensure quality compliance through traceability and batch control.

❓ Q2: What system or tools have you used for inventory control?
✅ Answer:
I’ve used ERP systems like SAP and Oracle, integrated with barcode scanning and automated
reorder triggers based on Min/Max levels. Tools like cycle counting, ABC/FSN analysis, and Power BI
dashboards help maintain control and visibility over fast-moving, critical stock.

❓ Q3: How do you ensure inventory accuracy?

✅ Answer:
I implement a perpetual inventory system using barcode scanning for real-time updates, along with
regular cycle counts. Discrepancies are flagged, investigated, and adjusted through defined SOPs.
Root cause analysis helps prevent repeat errors.

❓ Q4: What are some key KPIs you monitor in inventory control?

✅ Answer:

 Inventory Turnover Ratio (ITR)

 Stock Accuracy %
 Shrinkage %
 Stock out frequency
 Holding cost vs value

CASE STUDY: Inventory Control Failure in an MNC Warehouse

📌 Background:
An MNC warehouse handling critical electronic raw materials used a periodic inventory system with
minimal automation. No cycle counting was in place. Manual records were maintained in Excel.

📊 Scenario:

A customer order required 500 units of a special IC chip (Item Code: IC-XP900). The system showed
850 units available. Upon physical verification before dispatch, only 320 were found in usable
condition.

🔍 Root Cause Analysis:

 Phantom stock: Stock adjustments weren’t updated after issuing material to R&D trials.
 No cycle counts: Errors built up over 6 months.
 ERP entries were bypassed for urgent issues, leaving physical vs system stock mismatched.
 No lot traceability to link material issued outside of production.

🎯 Impact:

 Delay of 7 working days in dispatch

 Escalation from customer resulting in penalty of ₹1.2 lakh
 Internal audit flagged material handling and ERP discipline failures

🛠️Corrective Action Plan:

 Shift to a Perpetual Inventory System with daily auto-sync

 Implemented barcode tracking and handheld scanners
 Trained store staff to issue only through ERP
 Weekly cycle counting initiated for A-category items
 Lot-wise GRN/Issue mandatory for all R&D movements

✅ Outcome (3 months later):

 Inventory accuracy improved from 78% to 98.9%

 No stock outs or phantom stock in last 6 audits
 Restored customer trust and regained schedule performance

🎯 Mock Interview Questions & Answers: Material Indent to Receipt Process

❓Q1. Can you walk us through the complete process from material indent to receipt in the
store?

✅ A:
Certainly. The process starts when a department raises a material indent in the ERP. This indent
goes for approval by the concerned manager. Once approved, a purchase requisition (PR) is
generated automatically. The purchase team then converts it into a purchase order (PO) and shares
it with the vendor. Upon dispatch, materials are received at the store gate, verified for quantity and
quality, and then a Goods Receipt Note (GRN) is created in the ERP. Finally, the items are stored in
designated bins with full tagging and system update.

❓Q2. How do you ensure accuracy and avoid duplicate indents or orders?

✅ A:
We use ERP validations to check for duplicate indents, auto-rejection of repeated requests within
the same cycle, and approval hierarchies. I also run a daily pending indent report and cross-check
with consumption history and safety stock levels.

❓Q3. What controls do you have during material receiving?

✅ A:
We follow a 3-way match (PO, invoice, delivery challan). On receiving, we check:

 PO number and item code

 Quantity and condition of goods
 Vendor compliance documents (COA, MSDS) We perform physical inspection and random
QA checks before accepting and generating GRN in the ERP.

❓Q4. What challenges have you faced in this process and how did you overcome them?

✅ A:
Once we faced frequent delays due to late approvals, so I introduced a SLA-based digital approval
system in the ERP. In another case, vendors were sending wrong items, so we implemented a
barcode scanning system at gate entry linked to PO.

❓Q5. How do you track pending indents or deliveries?

✅ A:
I maintain a live tracking dashboard in ERP that shows:

 Indents pending approval

 PR to PO conversion status
 Open POs vs Received GRNs I also run weekly coordination meetings with purchase and
production to clear bottlenecks.

❓Q6. How is ERP integrated into the indenting and receiving process?
✅ A:
ERP is used at every step:

 Indent raising and approval

 Auto PR and PO generation
 Vendor database and lead times
 GRN creation and real-time stock update This ensures transparency, traceability, and data-
driven decision-making.

❓Q7. Give a scenario where this process saved production from downtime.

✅ A:
We had a critical machine part failure. I used our ERP to raise an emergency indent, got it auto-
escalated for immediate approval, and initiated a spot PO. We tracked the courier in real-time and
ensured delivery within 8 hours. GRN was created instantly, and production resumed without
downtime.

RGP – Returnable Gate Pass

💼 Mock Interview – RGP (Returnable Gate Pass)

❓Q1. What is an RGP, and why is it important?

✅ A:
An RGP (Returnable Gate Pass) is a document issued when materials are sent outside the company
premises with the intent to return. It ensures accountability, traceability, and control over assets
going out temporarily. It is essential to prevent material loss, ERP discrepancies, and audit non-
compliance.

❓Q2. What key information does an RGP include?

✅ A:
It includes:

 RGP number and date

 Item description and quantity
 Department raising the request
 Purpose (e.g., repair, testing)
 Vendor details
 Expected return date
 Approver's signature and vehicle details

❓Q3. How do you track RGPs after the material is dispatched?

✅ A:
We maintain a central RGP tracker (in ERP or Excel) which logs all open RGPs with expected return
dates. Weekly auto-emails are triggered for overdue RGPs. The store team also follows up with
vendors manually if required. We do a weekly reconciliation and share pending RGPs with the
respective departments.

❓Q4. What do you do when an RGP item returns?

✅ A:
We verify the item physically and match it with the original RGP in the system. Once confirmed, we:

 Mark the RGP as "Closed" in ERP

 Update the return date
 Perform a quality check if needed
 File the hardcopy or archive the digital entry

❓Q5. How do you handle a situation where the item is not returned by the due date?

✅ A:
First, we send reminders. If still not returned, we:

 Escalate to the department or procurement team

 Freeze future dispatches to that vendor (in critical cases)
 Update remarks in the system for audit trail In ERP, we tag it as “Overdue – Follow-up in
Progress.”

❓Q6. Can ERP automate the RGP process?

✅ A:
Yes. Most modern ERPs allow:

 Auto-generation of RGP numbers

 Auto-email alerts before due dates
 Status tracking (Open, Closed, Overdue)
 Integration with GRN and MRR modules for seamless closure

Scenario-Based Case Study: Delayed Return & Mismatch

📘 Case:

Your store issued an RGP on March 1, 2025, for two hydraulic pumps sent to Alpha Engineering Ltd.
for rework. The expected return date was March 10, 2025. On March 20, only one pump was
returned, and it was found to be non-functional and without documentation. The ERP still shows
the RGP as open.

🧩 Panel Questions:

❓Q1. What are the first three things you would do in this situation?

✅ A:

1. Immediately verify the returned item physically and update the partial return in the ERP.
2. Mark one pump as “Returned – Under Verification” and the other as “Pending Return”.
3. Raise a discrepancy report and notify QA and the requesting department.

❓Q2. How would you address the missing item and non-functional return?

✅ A:
I would escalate the issue to the vendor through Purchase and request a root cause report.
Simultaneously, I’d start a non-conformance report (NCR) in our quality system and mark the RGP
entry as “Disputed – Under Review” to prevent accidental closure.

❓Q3. What system improvements would you suggest to prevent this in future?

✅ A:

 Implement RGP barcode scanning for outward and inward validation

 Integrate mandatory document checks during return
 Enable ERP alerts for overdue RGPs and partial return workflows
 Conduct quarterly RGP audits with department sign-offs

❓Q4. If an audit occurs tomorrow, how will you defend this case?

✅ A:
I’ll show the RGP tracker, email trails, and system logs showing:

 RGP issuance and dispatch

 Partial return log
 Follow-up communications
 NCR raised
this proves that our process is robust and the issue is being transparently handled.

Material Rejection – Meaning

Material rejection refers to the process of refusing to accept goods that do not meet the required
quality specifications or standards during inward inspection, production, or post-delivery stages.
This process ensures that only conforming materials enter production or inventory, safeguarding
product quality, customer satisfaction, and compliance.

🔁 Material Rejection Process

Here's a step-by-step breakdown:

1. Material Receipt
o Material is received from vendor and entered into ERP/store register.
2. Quality Inspection
o Quality team performs tests (physical, chemical, dimensional).
o Results compared to Purchase Order (PO) specifications or standard parameters.
3. Rejection Decision
o If non-conforming, QA issues a Material Rejection Note (MRN).
o ERP status is updated: “Rejected – Hold”.
4. Segregation & Quarantine
o Material is tagged as REJECTED and moved to Quarantine Area.
o Not stored with accepted inventory to avoid mixing.
5. Communication
o Purchase team is notified for further action.
o Vendor is informed with MRN, photos, and test results.
6. Disposition
o Options include: Return to Vendor (RTV), Rework, Scrap, or Use-as-is (under
deviation approval).
7. ERP Update
o Rejected material is deducted from available stock.
o Status updated to “Closed” after resolution.

📈 Merits of a Strong Rejection Process

 Prevents defective items from affecting final products

 Builds quality accountability with vendors

🎤 Mock Interview Questions & Answers: Material Rejection Handling

❓ Q1: What is your process when materials fail quality inspection?

✅ Answer: “When materials fail inspection, I immediately initiate a Material Rejection Note (MRN),
move the stock to a tagged quarantine zone, and update the ERP to reflect its rejected status. I
coordinate with the quality and procurement teams, inform the vendor, and proceed with corrective
actions like RTV, rework, or controlled usage.”

❓ Q2: How do you ensure rejected materials don't accidentally enter inventory?

✅ Answer: “I enforce strict segregation protocols. Rejected materials are clearly tagged in red and
moved to a physically separate quarantine area. Access is restricted, and the ERP reflects the
rejection status, which prevents them from being picked or issued.”

❓ Q3: What role does ERP play in rejection tracking?

✅ Answer: “ERP helps ensure traceability by tagging rejected materials against their PO and batch
number. It locks the inventory, prevents issuance, and allows us to track vendor rejection rates. We
also use it to generate RTV notes, debit memos, and closure reports.”

❓ Q4: Have you faced recurring rejection from a vendor? What did you do?

✅ Answer: “Yes, a vendor supplying synthetic resin had 3 rejections in 2 months. I escalated to QA
and purchase. We initiated an 8D corrective action report, asked for a process audit, and temporarily
blacklisted the vendor until compliance improved.”

❓ Q5: How do you close a material rejection case?

✅ Answer: “Once the disposition is completed—whether return, rework, or approved usage—I

update the ERP, file the signed MRN, and close the rejection loop. The QA report and vendor
communication are archived for audit.”

🧪 Scenario-Based Case Study: Defective Consignment from a Critical Vendor

📦 Background:

You are the Assistant Store Manager in an MNC that produces automotive components. A key
vendor has sent 5 tons of alloy steel rods, critical for the brake system line. On receipt, your QA flags
micro-cracks in 20% of the batch.

🔍 Scenario Breakdown:

 PO Amount: ₹15,00,000
  Inspection Result: 1-ton rejected
 Production Demand: Urgent, within 2 days
 Vendor Reputation: Tier-1, with 98% on-time delivery in the past year
 ERP Status: Auto-blocked upon QA rejection

💡 Your Task:

You're asked in the interview:

“How will you manage this rejection while minimizing impact on production?”

✅ Model Answer:

“First, I’ll ensure the 1-ton of defective rods is isolated and tagged in our rejection area. I’ll issue the
MRN and update ERP to freeze its availability. Next, I’ll notify QA and Purchase, and share the MRN
with the vendor along with test reports and photos. Meanwhile, I’ll review the balance 4 tons for
safety and check if a short-term workaround is possible under deviation approval from QA.

Simultaneously, I’ll speak with planning to realign production if possible. If not, I’ll request the
vendor to expedite a replacement or send a service engineer to rework on-site. I’ll also update
management through a deviation report and ensure every communication is traceable in the ERP
and vendor portal. Once resolved, I’ll close the rejection loop and flag this case for future vendor
reviews.”

GRN (Goods Receipt Note) – Full Explanation

✅ Meaning:

A Goods Receipt Note (GRN) is an official document prepared when materials are received into the
store/warehouse.
It confirms the quantity, quality, and condition of goods received as per the Purchase Order (PO)
and serves as the basis for stock updating and payment processing.

🧾 Key Contents of GRN:

 Received: 980 kg
 Damaged: 10 kg
 Accepted: 970 kg
 GRN prepared for 970 kg
 10 kg recorded under rejection & tagged
 ERP updated, vendor notified, and payment scheduled accordingly.

🎤 Mock Interview Questions & Model Answers on GRN Handling

❓ Q1: What is a GRN, and why is it important?

✅ Answer:

"A GRN or Goods Receipt Note is a document generated when materials are received into the
warehouse. It confirms the received quantity and quality against the PO. It’s crucial because it
ensures inventory accuracy, initiates quality inspection, and triggers the payment process via a 3-
way match (PO-Invoice-GRN) in ERP."

❓ Q2: How do you verify the accuracy of a GRN?

✅ Answer:

"I verify the physical delivery against the PO in terms of quantity, unit of measure, and item
description. Then, I coordinate with quality to confirm specifications and batch details. Only after QC
clearance do I create the GRN in the ERP. I also ensure no duplicate GRNs are generated."

❓ Q3: Can you walk us through your GRN creation process?

✅ Answer:

"Once material arrives, I cross-check the delivery note against the PO. After QA clearance, I enter
details like item code, quantity, batch, and lot numbers into the ERP. I tag the material, update stock
levels, and forward the GRN to the accounts team for payment processing."

❓ Q4: How does GRN support vendor performance evaluation?

✅ Answer:

"Each GRN is tied to the vendor’s PO, so I track delays, shortages, damages, and rejection trends.
These metrics help evaluate vendor reliability, on-time delivery percentage, and quality
performance, which are shared with the procurement and quality teams regularly."

❓ Q5: What would you do if there's a mismatch between the PO and received goods?

✅ Answer:

"If there's a mismatch, I immediately hold the GRN creation, inform procurement, and escalate the
issue to the vendor. Depending on the situation—overdelivery, short supply, or non-conformance—I
may raise a partial GRN or reject the consignment completely."

❓ Q6: How is GRN integrated with ERP systems?

✅ Answer:

"In ERP, the GRN is linked directly with the PO and invoice modules. It automatically updates stock
levels and triggers a 3-way match before the finance team processes vendor payment. It also
updates batch traceability, expiry tracking, and FIFO/LIFO allocations."

❓ Q7: Have you faced any issues due to wrong GRN entries? How did you resolve them?

✅ Answer:
"Yes, once a GRN was wrongly posted with an excess quantity due to a manual entry error. It led to
stock mismatch and early payment. I reversed the GRN with proper documentation, updated the
correct stock, and coordinated with accounts to hold the payment."

❓ Q8: How do you handle partially received goods?

✅ Answer:

"For partial deliveries, I raise a GRN only for the quantity received. I mention the pending quantity in
the remarks and follow up with procurement and vendor. The balance GRN is created once the
remaining goods arrive and pass inspection."

❓ Q9: What controls do you implement to prevent duplicate GRNs?

✅ Answer:

"In ERP, each GRN is linked to a PO and has a unique ID. I ensure the PO is locked after full receipt
and payment. I also cross-check with the invoice and delivery note to avoid duplication. Manual
GRNs are numbered and tracked in sequence."

❓ Q10: How does GRN help in audit and compliance?

✅ Answer:

"GRNs serve as a traceable record of material entry and inspection. Auditors use them to validate
vendor bills, check stock discrepancies, and ensure PO-policy compliance. We keep scanned GRNs,
MRNs, and QA reports on file for at least 3–5 years for traceability."

Consumption – Meaning, Process, and Application

What is Consumption?

Consumption refers to the actual use of materials from inventory for production, maintenance,
repair, or service purposes.
It marks the reduction of stock in the system once materials are issued and physically used.

🧾 Where It Applies:

Type of Consumption Example

Production Consumption Raw materials issued for manufacturing

Maintenance Consumption Spares used in equipment repair

Service Consumption Consumables used in field service kits

Project Consumption Civil or infra projects using cement, steel

🔁 Consumption Process Flow:

 1. Material Indent Raised
→ From production, maintenance, or other departments.
2. Issue Slip Created
→ Store picks and issues material with authorization.
3. ERP Entry – Consumption
→ Inventory reduced in the system and cost center is charged.
4. Physical Use in Operation
→ Material is consumed at the job location.
5. Reporting & Traceability
→ Consumption report shows usage vs plan.

🧠 Key Points in ERP:

 Consumption is transactional, not just issuance.

 Can be tracked by job number, cost center, or batch.
 Important for costing, WIP tracking, variance analysis.
 Supports Material Requirement Planning (MRP) feedback.

📊 Common Consumption Types in ERP (SAP/Oracle/others):

 Planned Consumption – as per BOM (Bill of Materials).

 Unplanned Consumption – emergency/spontaneous usage.
 Backflushing – automatic consumption based on production.

⚙️Importance of Accurate Consumption:

 Prevents stock mismatch.

 Enables accurate costing and profitability analysis.
 Avoids overstocking or understocking.
 Essential for audit and compliance.

💬 Example for Interview:

"In our store, we link consumption to production orders in ERP. Once the material is issued, actual
consumption is tracked through backflush or manual confirmation. This gives visibility into WIP and
also helps us analyze yield losses or abnormal usage."

🎤 Mock Interview Q&A: Material Consumption

❓ Q1: What is material consumption, and how is it recorded?

✅ Answer:

"Material consumption refers to the actual usage of inventory in production or maintenance

activities. It is recorded in the ERP system after the material is issued and used. Depending on the
setup, consumption can be tracked manually, through production confirmations, or via automatic
backflushing."

❓ Q2: How do you differentiate between issuance and consumption?

✅ Answer:

"Issuance is the transfer of materials from the store to production or maintenance areas, while
consumption is the physical usage of those materials. Issuance reduces stock, but consumption links
the usage to a job order or cost center, affecting cost tracking."

❓ Q3: How do you handle excess consumption or variance from BOM?

✅ Answer:

"Excess consumption is flagged in ERP by comparing actual usage to the BOM. I investigate the cause
—whether due to rework, scrap, or planning error—and coordinate with production and planning to
approve and document the variance before updating the ERP."

❓ Q4: What steps do you take to ensure accurate consumption reporting?

✅ Answer:

"We validate job orders, cross-check BOMs, and only allow authorized issues. We perform cycle
counts and material reconciliations, especially for high-value or batch-controlled items. In ERP, we
use batch traceability and lot-based consumption tracking."

❓ Q5: Can you explain how ERP automates material consumption?

✅ Answer:

"In ERP systems, we use 'backflushing,' where consumption is automatically recorded based on
production confirmation. For example, if a finished good is confirmed in SAP, all associated raw
materials are consumed in proportion to the BOM."

❓ Q6: What controls do you implement to prevent over-consumption?

✅ Answer:

"We implement consumption caps per job order, strict MTO (Make to Order) controls, and alert
triggers in ERP when actual usage exceeds tolerance limits. We also lock issuance beyond approved
levels without supervisor escalation."

❓ Q7: How do you track consumption for serialized or batch-controlled

materials?

✅ Answer:

"We use ERP features like batch management or serial number tracking. At issuance, batch details
are captured, and during consumption, we ensure traceability for compliance and quality audits—
especially in pharma or aerospace environments."

❓ Q8: How do you manage unplanned consumption?

✅ Answer:

"Unplanned consumption is allowed only with a supervisor’s request and proper documentation. It’s
entered manually into ERP and linked to a work order or cost center. We analyze unplanned usage
monthly to identify root causes."

❓ Q9: What challenges have you faced in consumption tracking?

✅ Answer:

"In one instance, wrong BOM mapping led to under-consumption in ERP, which caused cost under-
reporting. We identified the issue during audit, corrected the BOM, and implemented an approval
step for any BOM changes."

❓ Q10: How does consumption data support inventory planning?

✅ Answer:

"Consumption data feeds into MRP for future demand planning. It also helps forecast reorder levels,
analyze slow/fast movers, and assess yield efficiency. We use monthly consumption trends to
propose inventory adjustments."

HSN Code – Meaning, Purpose, Structure, and

Classification
✅ 1. Meaning of HSN Code

HSN stands for Harmonized System of Nomenclature.

It is an internationally standardized system of naming and classifying goods used in trade and
taxation, particularly under GST (Goods and Services Tax) in India.

✅ It is developed by the World Customs Organization (WCO) and is used globally for identifying
goods in a systematic and consistent manner.

🎯 2. Purpose of HSN Code

Purpose Explanation
📋 Classification of Goods Assigns a uniform code to every product traded.
💸 Taxation (GST, Customs, Excise) Determines applicable tax rates for goods.
🌍 International Trade Facilitates global import/export through standard codes.
📊 Data & Analytics Helps in economic, statistical, and policy analysis.
🔄 Automation in ERP Integrates seamlessly in tax invoicing and stock ledgers.

🧱 3. Structure of HSN Code

The HSN Code is typically 6 to 8 digits, structured hierarchically:

 Level Digits Description
Chapter 2 digits Broad category of goods (e.g., 84 = Machinery)
Heading 4 digits Specific group under chapter (e.g., 8408 = Engines)
Subheading 6 digits More detailed classification (e.g., 840890 = Engine parts)
National level 8 digits (India-specific) for detailed GST classification

🔎 Example:
HSN 84089010

 84 = Machinery
 8408 = Engines
 840890 = Other parts
 84089010 = Parts suitable for aircraft engines

🧾 4. Classification of HSN

HSN codes are grouped under 21 sections and 99 chapters, covering 5,000+ products.

Some Examples:

Chapter Description Example HSN

02 Meat and Edible Meat Offal 0201 – Meat of bovine animals
39 Plastics and articles thereof 3923 – Plastic containers
84 Machinery & Mechanical Appliances 8414 – Air pumps & compressors
85 Electrical Machinery 8504 – Transformers, static converters

⚙️5. Use in ERP & Store Management

 Every inventory item must have an HSN code assigned.

 Used for auto tax calculations in GST billing modules.
 Enables GST compliance reports (GSTR-1, GSTR-3B).
 Helps during material classification, GRN, and consumption entry.

🧠 Bonus – HSN vs SAC

HSN SAC
For Goods For Services
6-8 digit codes 6-digit codes
Used in material movement Used in service billing

📌 Interview Tip

"In our ERP, each SKU is mapped with the correct HSN code to ensure tax compliance and proper
classification for both GST and customs. This also helps in preparing audit reports and HS-wise
consumption trends."

🎤 Mock Interview Q&A: HSN Code

❓ Q1: What is the HSN code?

✅ Answer:
"HSN stands for Harmonized System of Nomenclature. It is a globally accepted system developed by the
World Customs Organization to classify goods in a standardized manner. In India, HSN is used under GST
to categorize goods and apply appropriate tax rates."

❓ Q2: Why is the HSN code important in store operations?

✅ Answer:

"HSN codes are crucial for correct tax calculation, proper material classification, inventory reporting, and
audit compliance. They ensure accurate GST invoicing and help avoid errors in documentation, especially
during procurement and goods receipt."

❓ Q3: How is the HSN code structured?

✅ Answer:

"HSN codes are typically 6 to 8 digits. The first 2 digits represent the chapter, the next 2 indicate the
heading, and the next 2 are subheadings. In India, we add 2 more digits for deeper classification under
GST, making it an 8-digit structure."

❓ Q4: How do you assign HSN codes in your store or ERP system?

✅ Answer:

"We classify every item in our material master data with an HSN code at the time of item creation. We
use official GST HSN listings and consult with finance or tax teams when needed. The HSN is linked in ERP
for automatic tax application during PO and GRN."

❓ Q5: What is the consequence of using the wrong HSN code?

✅ Answer:

"Wrong HSN codes can lead to incorrect tax payments, GST return mismatches, audit penalties, or even
blocked input credits. It can also confuse compliance reports and impact vendor/customer relationships
during reconciliation."

❓ Q6: Can you explain the difference between HSN and SAC?

✅ Answer:

"HSN is used for goods, while SAC—Service Accounting Code—is used for services under GST. For
example, an item like a steel bolt has an HSN, while services like transportation or consulting will be
categorized under SAC."

❓ Q7: How do you manage HSN updates or changes?

✅ Answer:

"We review HSN updates released by GST Council periodically. If there's a change, we update the ERP
material master through a controlled change management process with version tracking, ensuring audit
trail and correct future invoicing."
❓ Q8: How do you verify the correctness of HSN codes in a GST audit?

✅ Answer:

"During GST audits, we generate HSN-wise sales and purchase registers from the ERP, cross-check them
with GST rate notifications, and ensure that all items match their tax slabs. We also conduct random
checks with vendors to ensure consistency."

❓ Q9: Can you give a real-world example where HSN coding helped avoid an issue?

✅ Answer:

"In one case, we identified that two similar items were incorrectly assigned the same HSN, although one
attracted 18% GST and the other 5%. We corrected it before filing GSTR-1, preventing a major mismatch
and saving penalty costs."

❓ Q10: What tools or reports do you use to analyze HSN-wise data?

✅ Answer:

"We use ERP-based HSN summary reports, GST returns, and BI dashboards. These help analyze HSN-wise
consumption, tax payment trends, and vendor-wise classifications. We also track high-risk or high-value
HSNs for scrutiny."

Job Work Challan – Meaning, Process, & Format

💼 Mock Interview Q&A – Job Work Challan (Store

Management/ERP/Operations Role)
❓Q1: What is a Job Work Challan, and when is it used?

✅ A:
A Job Work Challan is a non-commercial document used to send goods to a job worker for
processing, reworking, or assembly. It's used when ownership of goods remains with the principal
and there's no sale involved. It’s mandatory under GST Rule 45 and must accompany goods during
movement.

❓Q2: What are the mandatory contents of a Job Work Challan under GST?

✅ A:
A Job Work Challan must include:

 Challan number and date

 Principal’s name, address, and GSTIN
 Job worker’s details
 Description, HSN code, and quantity of goods
 Tax details (if applicable)
 Purpose (Job Work)
 Authorized signature

❓Q3: How do you track materials sent for job work in the ERP system?

✅ A:
In ERP, we tag materials issued under job work as "Stock with Job Worker." Each challan is linked
with a job work PO and tracked until GRN is done. Aging reports or auto alerts help monitor delays,
and reconciliation is done at closure.

❓Q4: What is the return period for goods under job work? What happens if
it’s delayed?

✅ A:
Inputs must be returned within 1 year and capital goods within 3 years. If not returned, the principal
is liable to pay GST on the deemed supply. We monitor aging using ERP dashboards and generate
reminders.

❓Q5: What steps are followed when processed goods are received back?
✅ A:
Upon return:

1. We receive goods with the return challan.

2. Perform quality/quantity check.
3. Generate GRN.
4. Match return quantity with original issue.
5. Update ERP stock and close job work challan if fully returned.

❓Q6: What ERP actions do you take for closing a job work challan?

✅ A:
We reconcile the issued vs. received quantities. After full return, we mark the PO and challan status
as "Closed" in the ERP. Documents are filed, and the entry is updated in the ITC-04 return (if
applicable).

❓Q7: What are common risks in job work challan processes? How do you
control them?

✅ A:
Risks include delayed returns, quantity mismatches, or lost challans. We mitigate these by:

 Using ERP-based tracking

 Setting return alerts
 Conducting monthly reconciliation
 Filing documents with checklists
 Ensuring ITC-04 returns are updated on time

❓Q8: Can you share an incident where a job work challan helped avoid
compliance failure?

✅ A:
Yes. Once, a vendor delayed returning a processed lot close to the 1-year limit. Our ERP aging report
flagged it, we followed up urgently, got the material returned and GRN issued. It helped avoid GST
liability and audit remarks.

What is subcontracting?
Subcontracting (also known as Job Work) is the practice of outsourcing a part of the production
process or service to an external vendor (subcontractor), while the principal manufacturer retains
ownership of the raw materials/components.

📦 Key Features of Subcontracting:

📌 Best Practices

 Automate reminders for return due dates (1 year for input, 3 years for capital goods).
 Use barcodes or QR codes for tracking lot-wise issue and return.
 Monthly reconciliation between ERP stock and subcontractor stock report.
 Conduct quarterly audits at subcontractor premises.

🎤 Mock Interview Q&A on Subcontracting Process

Q1: Can you explain the subcontracting (job work) process in your store operations?

Answer:
Yes. In subcontracting, we send raw materials to an external vendor for specific processing. We
initiate the process by raising a job work purchase order, issue a job work challan, and dispatch
materials. The ERP reflects this stock as "Stock with Vendor." Once processed material returns, we
perform physical and quality checks, generate a GRN, and close the PO after full reconciliation.

Q2: How do you track material sent to subcontractors?

Answer:
We track it using our ERP system, where every issued material under job work is marked as “stock
with subcontractor.” We also maintain a register and schedule periodic reconciliation. Aging reports
help us track delays, and barcode scanning helps ensure traceability of each lot or batch.

Q3: What challenges have you faced with subcontracting stock, and how did you solve them?

Answer:
One challenge was material not being returned within the statutory time frame (1 year). To fix this,
we implemented automated ERP alerts and created a quarterly subcontractor stock audit process.
Another issue was mismatch in returned quantity; we introduced batch-wise barcoding to ensure
accuracy.

Q4: How do you ensure timely closure of subcontracting orders?

Answer:
We reconcile issued and returned material quantities using GRN vs Challan matching in ERP. Any
pending quantity or scrap is discussed with the vendor. After final GRN and approvals, we close the
PO in ERP and archive the documentation.

Q5: What ERP features do you use to support subcontracting control?

Answer:
We use features like Job Work PO, Job Work Challan, Vendor Stock Reports, GRN Matching, and ITC-
04 integration. Alerts for pending returns and automatic closure workflows also help reduce manual
follow-up.

Q6: How do you manage physical stock verification at vendor sites?

Answer:
We conduct joint stock audits every quarter. The team visits the subcontractor site with our ERP
stock report, verifies physical material, and signs off on a reconciliation sheet. Discrepancies are
recorded and investigated before closure.

Q7: How do you handle missing or excess material during subcontract return?

Answer:
If material is missing, we investigate with the vendor, verify the scrap or process loss, and escalate if
needed. For excess returns, we cross-check PO and BOM for error or duplication. In both cases, we
update ERP after approval.

Q8: What documents are involved in subcontracting material movement?

Answer:
Key documents include:

 Job Work Purchase Order

 Job Work Challan
 Transport Document
 Material Receipt/GRN
 Reconciliation Sheet
 ITC-04 Return for GST

Q9: Have you handled a scenario where ERP showed incorrect stock at the vendor?

Answer:
Yes. Once, ERP showed more stock than physically available. We traced the error to a missed GRN
entry and duplicate challan. We corrected the ERP, adjusted the stock ledger, and trained staff to
double-check entries during receipt.

Q10: How do you ensure GST compliance during subcontracting?

Answer:
We file ITC-04 regularly as per GST guidelines. All job work challans are generated with HSN codes
and linked to PO. ERP alerts help us stay within the 1-year input return limit. Proper documentation
and digital records are maintained for audits.

Mock Interview – Gst In Store Management

❓ Q1: What is GST and how is it relevant to store operations?

Answer:
GST is a unified indirect tax on the supply of goods and services. In store operations, it's essential for
correctly recording material receipts, tax input credits, and issuing accurate invoices or challans. It
also governs transactions like purchase, returns, scrap sale, and job work material movement.

❓ Q2: How do you handle GST during inward material receipt?

Answer:
At GRN (Goods Receipt Note) stage, we verify:

 The vendor invoice includes correct HSN code and GST rate
  The ERP auto-captures CGST, SGST, or IGST
 The invoice is matched against PO and stored for ITC claim
We also ensure that the vendor is GST compliant (registered and active).

❓ Q3: Can you explain HSN code and why it is important?

Answer:
HSN (Harmonized System of Nomenclature) is a standardized code used for classifying goods. It
ensures that the correct GST rate is applied. For example, industrial lubricants and electrical parts
have different HSNs and rates. Wrong HSN codes can lead to penalties, incorrect ITC, and audit
issues.

❓ Q4: How is GST managed for Job Work?

Answer:
For job work:

 We issue materials under a Job Work Challan, not invoice.

 The job worker charges GST only on processing charges, not on materials.
 We track returnable material via ERP and file ITC-04 quarterly. If materials are not returned
within the permitted period (1 year), GST is payable.

❓ Q5: What is ITC and how do you ensure Input Tax Credit accuracy?

Answer:
ITC (Input Tax Credit) allows us to claim back the GST paid on purchases. To ensure accuracy:

 GRN and vendor invoices must match

 HSN and GST % must be correct
 Filing must be done monthly (via GSTR-3B) We also cross-check with GSTR-2B to validate
what the vendor has uploaded.

❓ Q6: How do you manage GST on returnable materials (RGP)?

Answer:
Materials sent under RGP (Returnable Gate Pass) do not attract GST if returned within 180 days. We
use ERP to:

 Track due dates

 Send alerts to vendors for pending returns
If materials aren't returned on time, GST may be applicable and noted during audits.

❓ Q7: How do you ensure ERP accuracy in GST-related transactions?

Answer:
ERP is configured with:

 Item-wise HSN codes

 Vendor-wise GST numbers
  Auto-calculation of tax based on delivery location (intra/interstate) Regular audits and
validations are done to ensure data consistency and prevent mismatch with GST portal
returns.

❓ Q8: Describe a challenge you faced related to GST in stores.

Answer:
A vendor once used the wrong HSN code on a high-value item, resulting in a mismatch during ITC
filing. We identified it during GRN audit, rejected the invoice, and requested correction. This
prevented a potential loss of ₹30,000 in ITC. Since then, we implemented an HSN validation
checklist in ERP.

❓ Q9: What is your role in GST audit preparedness?

Answer:
We maintain:

 GRN-wise invoice copies with GST details

 HSN summaries for monthly reporting
 ITC reconciliation logs
We also support finance in matching GSTR-2B with ERP entries and help close open GRNs or
pending returns before filing.

❓ Q10: How is scrap sale handled under GST?

Answer:
Scrap sales are taxable and must be invoiced with correct HSN and GST rate (usually 18%). We
generate GST invoices, maintain scrap registers, and ensure all sales are reflected in GSTR-1 and
accounted in ERP.

GSTIN – Meaning, Structure, and Purpose

What is GSTIN?

GSTIN stands for Goods and Services Tax Identification Number.

It is a 15-digit unique number assigned to every business registered under the GST Act in India.

🏗️Structure of GSTIN:

Example GSTIN: 27ABCDE1234F1Z5

Part Digits Meaning

State Code 27 First 2 digits represent the state (e.g., 27 = Maharashtra)

PAN ABCDE1234F Next 10 digits are the company’s PAN number

13th digit shows the number of registrations under the same PAN in
Entity Number 1
a state
 Part Digits Meaning

Default
Z 14th digit is usually ‘Z’ by default
Alphabet

Check Digit 5 15th digit is a check code for error detection

🎯 Purpose and Use in Store Management:

Use Case Explanation

✅ Vendor Validation Helps verify if the supplier is GST-compliant and eligible for ITC.

✅ Invoice Matching GSTIN must be correctly printed on tax invoices and GRNs.

✅ ERP Configuration Each vendor/customer is tagged with their GSTIN for tax automation.

✅ Filing & Audits All purchases and sales are reported against GSTIN in GSTR filings.

✅ Inter-state vs Intra-state GSTIN helps determine CGST+SGST (intra) vs IGST (inter) tax type.

Mock Interview Questions – GSTIN

❓ Q1: What is the role of GSTIN in the store’s ERP system?

✅ Answer: GSTIN is used to classify whether a transaction is inter-state or intra-state. ERP uses it to
auto-apply correct tax and to maintain vendor-wise compliance logs.

❓ Q2: What happens if a vendor provides an invalid GSTIN?

✅ Answer: Invalid GSTIN leads to mismatch in GSTR-2B vs ITC claims, potential rejection of credit,
and audit issues. We cross-verify GSTIN with the government portal before GRN.

❓ Q3: How do you ensure GSTIN correctness in your workflow?

✅ Answer: During vendor onboarding or PO release, we validate GSTIN against PAN and state code.
During invoice receipt, ERP flags any mismatch for correction before GRN.

❓ Q4: Can one PAN have multiple GSTINs? When and why?
✅ Answer: Yes, a company with operations in multiple states needs a separate GSTIN for each state.
Also, even within the same state, multiple units can have different entity codes.

errors. 5S ensures organized layout, clean workspaces, and safety — all essential for positive audit
outcomes.

Customer-End Audit in Store/Warehouse Operations

✅ What is a Customer-End Audit?

A Customer-End Audit is when the client (customer) visits your facility (warehouse, store,
manufacturing plant) to verify whether you meet their quality, delivery, process, compliance, and
inventory standards.

🔍 This audit ensures that your store or warehouse meets the customer’s SLA, safety, traceability,
and documentation expectations.

🔍 Purpose of Customer-End Audits

📘 Mock Interview Q&A – Customer-End Audit Focus

❓ Q1: What preparations do you do before a customer audit?

✅ Answer: We conduct a pre-audit check covering FIFO compliance, ERP-to-stock reconciliation,
traceability logs, and review of rejected/returned stock. We also ensure 5S and 3C are in place, all
labeling is proper, and RGP/NGRP are closed.

❓ Q2: How do you handle a situation where a customer finds a BOM mismatch during kitting?
✅ Answer: I would immediately review the ERP vs physical BOM, check issue slips, and identify if the
component was delayed or misissued. Then, I coordinate replenishment and update the CAPA to
prevent recurrence.

❓ Q3: What ERP features help you during customer audits?

✅ Answer: Features like batch/lot traceability, GRN tracking, expiry management, BOM linkage,
and real-time stock reports help ensure we provide transparent data. We also use audit trail logs to
show material movement history.

✅ Answer: By ensuring accurate inventory, full kit availability, clean processes (5S/3C), rejection
handling, and clear ERP documentation. Regular mock audits and cross-functional training are key to
being audit-ready always.

❓ Q5: What was a major audit non-conformance you faced, and how did you resolve it?
✅ Answer: A customer once found 2 lots mixed in a bin due to barcode failure. I traced the GRNs,
isolated stock, fixed ERP tagging, and initiated a full scan to revalidate the inventory. We later
upgraded to a dual-verification barcode system.

📊 Real-Time Customer Audit Case Study (Optional)

Would you like a scenario-based case study like:

“A customer audit team visits and finds that expiry-dated material was issued to production. How do
you handle the escalation, investigate, and present the RCA and action plan?”

Mock Interview – Store Management Tools Focus

✅ Q1: What are the key tools you use in store management, and how do they help operations?

Answer: I primarily use tools like ERP systems (SAP or Tally), barcode scanning, Excel-based stock
sheets, and cycle count tools. ERP centralizes transactions like GRN, material issues, and stock
tracking. Barcode tools reduce manual errors during issue or receipt. Automated Excel sheets help
with daily reporting, and audit tools like iAuditor streamline 5S and traceability audits. These tools
together improve accuracy, speed, and accountability.

✅ Q2: Can you explain how barcode or QR systems are used for inventory control?

Answer: Barcode or QR systems help in uniquely identifying materials or bins. We scan materials
during receipt (GRN) and during issue. The system updates inventory levels in real-time in the ERP.
It ensures FIFO compliance, traceability, and reduces human error. It’s especially useful in high-
volume or raw material warehouses.

✅ Q3: How do you use ERP in daily store operations?

Answer: ERP is our core platform. I use it for:

 Material receipts (GRN)

 Material issue slips (manual or BOM-based)
 Vendor tracking and RGP/NGRP
 Min-Max level alerts and reorder point tracking
 Lot traceability and batch expiry tracking
 Stock audit logs and discrepancy management

✅ Q4: Describe a time when automation helped reduce shrinkage or errors.

Answer: In one case, we had frequent mismatches during issue due to manual entry. After
introducing barcode scanners and integrating them with ERP, we reduced errors by 90%. The
automated stock sheet also highlighted unusual consumption, which helped identify a process leak
causing shrinkage.

✅ Q5: How do you handle tool breakdowns or ERP failures?

Answer: We maintain offline tracking sheets as a backup. For example, during an ERP failure, we
used Excel-based inward/outward registers with barcode scan logs. Once the system was back, we
reconciled and uploaded data manually with batch trace. Also, we raise IT tickets immediately and
ensure real-time escalation protocols.

✅ Q6: What KPIs do you track using store management tools?

Answer: Key KPIs include:

 Inventory Turnover Ratio (ITR)

 Cycle count accuracy
 FIFO compliance %
 Reorder alert response time
 Shrinkage % and root cause tracking
 On-time GRN and issue accuracy

✅ Q7: Have you implemented any tool or system independently?

Answer: Yes, I led the implementation of automated Excel stock sheets with macros. It included min-
max level calculation, alert dashboard, and GRN vs Issue log auto-match. It reduced manual workload
by 30% and helped in audit readiness with better tracking.

✅ Q8: How do store tools support audits or compliance checks?

Answer: Tools like ERP log history, barcode scan trails, and audit apps help provide instant data
during audits. GRN and MRN traceability is available in seconds. Document control systems ensure
every entry and signature is archived digitally, aiding ISO or customer audits.

One Part One Location (OPOL) – Full Explanation

🔍 Meaning:

"One Part One Location" means each material or SKU (Stock Keeping Unit) in the store/warehouse
is assigned a unique and dedicated storage location, with no mixing allowed across locations or
bins.

📌 "One item = One unique bin or rack location"

This principle improves visibility, inventory accuracy, and traceability — critical in ERP and FIFO
environments.

📦 ERP Bin Mapping Precise mapping with barcode/bin codes

🛠️Maintenance Rejected/obsolete items don't get reused accidentally

🧭 Process:

1. Part Classification: Define and code each item clearly (HSN/BOM-based)

2. Bin/Location Design: Assign one fixed location for each item in ERP
3. Label & Barcode: Place bin labels, part number tags, and barcode/QR codes
4. ERP Linking: Update ERP bin master data for each item
5. Training: Train store team to follow OPOL strictly
6. Enforcement: Reject or flag entries where mixed bins are attempted
7. Audit Checks: Periodic bin validation and traceability checks

🧩 Action Plan: (Step-by-Step)

Step Action

1️⃣ Create part master list with part number, UOM, criticality

2️⃣ Map bin/rack layout and assign unique location ID

3️⃣ Update ERP system to link each part to only one bin

4️⃣ Print and place bin labels with barcode/QR code

5️⃣ Set system block for duplicate bin assignment in ERP

6️⃣ Conduct weekly audits on bin accuracy and part mix issues

7️⃣ Report non-compliance and update SOP or retrain team

Mock Interview Q&A – One Part One Location (OPOL)

✅ Q1: What does 'One Part One Location' mean in store management?
Answer:
It means assigning a unique bin location to each item or material in the store, ensuring it is not
mixed with other parts. This improves traceability, avoids picking errors, and aligns with FIFO, ERP
mapping, and lean store practices.

✅ Q2: What are the key benefits of OPOL?

Answer:
Benefits include accurate inventory, faster picking, traceability for audits, easier cycle counting, and
avoiding material mix-ups. It also supports clean ERP transactions and helps meet customer and ISO
compliance standards.

✅ Q3: How do you implement OPOL in an existing store?

Answer:
Start with a part-bin mapping exercise, create location IDs, update ERP master, label each bin with
barcode, and retrain the team. Set validation checks in the ERP to prevent placing two parts in one
bin.

✅ Q4: How do you handle shortage of space while implementing OPOL?

Answer:
We prioritize critical parts for OPOL. For non-critical or slow-moving parts, we assign bulk storage
separately but maintain ERP mapping. Vertical bin storage and rack optimization can also help
resolve space constraints.

✅ Q5: How do you verify compliance with OPOL during audits?

Answer:
We conduct bin-wise random audits using barcode scans and compare with ERP records. Any
mismatch is reported for corrective action. Monthly audit reports are shared with operations or QA
teams.

Shelf Life Material: Meaning & Handling Process

📌 1. Meaning of Shelf Life Material:

Shelf life material refers to items or products with a limited usable period, beyond which they
deteriorate or become unfit for use. These materials require strict date-based tracking to ensure
quality, safety, and compliance.

📅 Common Shelf Life Materials:

 Adhesives, sealants, paints, chemicals

🎯 Mock Interview Questions & Answers: Shelf-Life Material

Handling
❓Q1: What do you understand by shelf-life material?

Answer:
Shelf-life materials are products with a predefined usable time limit, beyond which they lose their
physical, chemical, or functional properties. These include chemicals, adhesives, pharma items,
rubber components, and food-grade goods. Managing them requires accurate batch tracking,
FIFO/FEFO usage, and ERP alerts to avoid expiry-related issues.

❓Q2: How do you track shelf-life materials in your store?

Answer:
We track shelf-life materials using the ERP system by entering batch numbers, MFG, and expiry
dates at the time of GRN creation. The system auto-generates alerts before the expiry date, blocks
expired stock, and enables FEFO issuance. Physically, we store them in labeled racks with visual
markers and expiry bins.

❓Q3: What is the difference between FIFO and FEFO? Which one applies to
shelf-life materials?

Answer:
FIFO (First In, First Out) issues the oldest received material first, based on receipt date. FEFO (First
Expired, First Out) prioritizes materials nearing expiration, regardless of receipt date.
FEFO is critical for shelf-life materials to minimize wastage and ensure quality and compliance.

❓Q4: How do you ensure expired stock is not issued by mistake?

Answer:
We configure our ERP to automatically block expired lots during picking or issuance. Additionally, we
use color-coded labels (e.g., red for expired, yellow for near expiry), perform regular shelf-life
audits, and place physical controls like expiry quarantine racks to avoid manual errors.

❓Q5: What actions do you take when a material is nearing expiry?

Answer:
We identify such stock through ERP alerts or cycle count reports. Then:

 Prioritize usage in production (if valid).

 Notify planning and quality for fast movement or transfer.
 Seek revalidation from QC if possible.
 Initiate return-to-vendor or create scrap note if unusable.

❓Q6: Can you share a scenario where improper shelf-life tracking caused an
issue?

Answer:
Yes. In my previous role, a batch of adhesive with a 6-month shelf life was received but not labeled
correctly. It was picked 8 months later and used in production, leading to bond failure during QA
testing. This led to a full batch recall. Post-incident, we implemented FEFO controls, digital labeling,
and shelf-life review protocols in ERP.

❓Q7: What ERP features help in shelf-life management?

Answer:

 Batch & expiry tracking at GRN

 FEFO-based picking logic
 Expiry alerts and color codes
 Auto block post-expiry
 Integration with QA for revalidation workflows These features ensure proactive inventory
rotation and minimize risk.

❓Q8: What audits do you conduct for shelf-life materials?

Answer:
We conduct:

 Weekly/Monthly shelf-life audits

 Spot checks during cycle counting
 Expiry inventory reviews before physical inventory
 Compliance audits for regulated materials (e.g., pharma, chemicals)

These audits are documented and validated with QA and ERP reports.

Stock Reconciliation Process – Full Breakdown

What is Stock Reconciliation?

Stock reconciliation is the process of comparing physical stock available in the store with
the stock recorded in the ERP/system to identify any mismatches (shortage, excess, wrong
batch, or location errors) and take corrective action.

🔄 Step-by-Step Process Flow:

Step Description

🔍 Common RCA (Root Causes) in Reconciliation Gaps:

 GRN not posted

 Wrong UOM conversion
 Material issued manually but not updated in ERP
 Duplicate entries
 Batch expiry clearance without ERP update
 Pilferage or damage not recorded

🎤 Mock Interview Q&A: Stock Reconciliation

❓Q1. What is stock reconciliation, and why is it necessary?

Answer:
Stock reconciliation is the process of comparing the physical inventory in the store with the
stock shown in the ERP system to identify discrepancies. It ensures data accuracy, supports
audits, and helps maintain trust in inventory valuation and supply chain performance.

❓Q2. What are the most common reasons for mismatch between ERP and
physical stock?

Answer:
Some common causes include:

 GRN not posted

 Manual issue not updated in ERP
 Expired stock not cleared from system
 Wrong bin or batch selection during picking
 Cycle count errors or missed items

❓Q3. How do you handle stock mismatch when it’s identified?

Answer:
We first document the difference, then conduct an RCA to find the reason (human error,
system issue, theft, etc.). After justification, we raise a stock adjustment note for approval
from the store head or finance, and only then do we update the ERP. Audit trail is maintained.

❓Q4. Who approves stock adjustment entries in your process?

Answer:
Stock adjustment is generally approved by the Store Manager, and Finance/Accounts team,
or sometimes by an internal auditor depending on company policy. Approval is done before
any ERP correction.

❓Q5. Can you describe a real example when you found a major variance
during reconciliation?

Answer:
During a cycle count, we noticed a shortage of 200 units of a critical fast-moving item. RCA
showed a manual emergency issue was made during ERP downtime and not back-entered.
We traced the usage, adjusted the stock post-approval, and updated the SOP for downtime
stock movement.

❓Q6. How do you prevent such mismatches from repeating?

Answer:
We implemented stricter controls like:

 Real-time ERP updates

 No manual issues without ERP entry
 Barcode scanning at issue/receipt
 Monthly stock audits of critical SKUs
 Training of staff for ERP discipline

Audit Non-Conformity Handling in Store Operations

What If a Store Fails an Audit?

When a store fails an audit (internal, external, customer-side, or third-party), it usually means:

 Processes were not followed

 System or physical discrepancies exist
 Compliance issues (like FIFO/LIFO, safety, storage)
 Documentation lapses or ERP traceability gaps

Immediate steps after failure:

1. Non-Conformance Report (NCR) is issued.

2. A Corrective and Preventive Action (CAPA) plan must be submitted.
3. The store is given a deadline for closure and re-audit (if required).
4. The issue is tracked until closed.

🛠️How to Create a CAPA (Corrective Action and Preventive Action)

CAPA Step Description

Clearly state what went wrong (e.g., wrong location, missing GRN,

Closure through review or mini-audit.

📑 Document Trail & ERP Traceability

To ensure audit readiness and compliance:

 Maintain NCR register (physical or ERP-linked).

 Each CAPA should be recorded with date, status, and responsible person.
 Ensure ERP traceability of:
o Adjustments
o Material movement logs
o GRN / rejection history
o Shelf-life tracking
o RGP/NRGP entries

Tools used:

 Audit Checklist Logs

 ERP NCR/Deviation Tracking
 Email threads/approval notes
 Physical sign-off sheets (where applicable)

🎤 Mock Interview Q&A on Audit Non-Conformity & CAPA

❓Q1. What actions do you take if your store fails an audit?

Answer: First, I review the Non-Conformance Report in detail. Then, I conduct a root cause analysis
with my team to understand the issue, document the findings, prepare a CAPA, and get approval. We
ensure corrective action is closed immediately and preventive measures are implemented to avoid
future issues.

❓Q2. Can you explain what a CAPA is and how you build it?

Answer: CAPA stands for Corrective and Preventive Action. Corrective action fixes the current issue,
while preventive action ensures it doesn't repeat. We first do an RCA, then document both sets of
actions with ownership and deadlines. All steps are tracked until closure and verified in follow-up
audits.

❓Q3. How do you maintain audit traceability in ERP?

Answer: All actions—like stock adjustments, approvals, rejection notes, RGP returns—are logged in
the ERP with reference numbers. We also tag CAPA to audit entries where the system allows, or
maintain a document repository linked to ERP item masters and transaction IDs.
 ❓Q4. Describe a situation where a preventive action you implemented helped in the next audit.

Answer: In one case, we failed an audit due to expired materials lying in the bin. We fixed it
immediately, but also added a preventive action by configuring expiry alerts in the ERP and trained
staff to check expiry while picking. The next audit praised our proactive expiry management.

❓Q5. What challenges do you face during audit closures and how do you overcome them?

Answer: Challenges include lack of documentation, untrained staff, or poor ERP discipline. I
overcome this by conducting refresher training, setting reminders for compliance checks, and creating
SOPs that everyone can follow with ownership mapped in ERP.

Answer:
Key KPIs include Inventory Accuracy, Inventory Turnover Ratio (ITR), Cycle Count Coverage %,
Near Expiry %, and GRN Delay. These KPIs ensure stock health, cost control, and readiness for
audits and production.

❓Q2. How do you track these KPIs?

Answer:
I track them using ERP data extracts analyzed in Excel or Power BI dashboards. I ensure KPI
visibility by updating daily or monthly reports which are reviewed by the store head and shared with
management.

❓Q3. What action do you take when KPI targets are missed?

Answer:
I initiate RCA to find the root cause, propose corrective steps like re-training or process improvement,
and submit the deviation report with a revised action plan. For example, if Inventory Accuracy drops,
we review posting discipline and re-train staff.

❓Q4. How does Power BI help in store reporting?

Answer:
Power BI allows real-time, interactive dashboards. It helps visualize trends, compare performance
across months or teams, and enables drill-downs by SKU, location, or employee. It also supports
alerts for critical issues like near-expiry items.

❓Q5. Can you describe a case where KPI reporting helped avoid loss?

Answer:
Yes, in one month, our Near Expiry % crossed 7%. The dashboard highlighted it in red. We quickly
isolated the items, reallocated to high-consumption departments, and avoided stock wastage worth
₹1.2 lakhs.

📌 KPI – Meaning
KPI (Key Performance Indicator) is a measurable value that demonstrates how effectively
a person, team, or department is achieving key business objectives. In store operations, KPIs
are used to monitor, improve, and control inventory, performance, accuracy, and compliance.

🎤 Mock Interview Q&A: Store & Assistant Store Manager KPIs

❓Q1. What is a KPI, and why is it important in store operations?

Answer:
A KPI is a measurable indicator that shows how effectively key goals are being met. In store
operations, KPIs track accuracy, efficiency, compliance, and responsiveness. They help in
reducing shrinkage, improving traceability, and ensuring timely stock availability.

❓Q2. What are the top 3 KPIs you monitor regularly in a store?

Answer:
 1. Inventory Accuracy
2. Material Issue TAT (Turnaround Time)
3. Near Expiry %

These directly impact production readiness, cost savings, and quality control.

❓Q3. How do you measure Inventory Turnover Ratio (ITR), and why is it
important?

Answer:
ITR = Cost of Goods Sold ÷ Average Inventory
It helps assess how quickly inventory is being consumed or sold. A higher ITR means less
capital is tied up in inventory.

❓Q4. What actions do you take when a KPI drops below the target?

Answer:
I immediately analyze the root cause (RCA), identify if it's due to process, manpower, or
system error, and then implement a Corrective Action Plan. I also communicate this in my
monthly review reports.

❓Q5. How do you track KPIs? Do you use any software?

Answer:
Yes, we use ERP for data extraction and either Excel or Power BI for dashboarding. These
tools help visualize daily trends and set alerts for issues like nearing expiry or GRN delays.

❓Q6. Describe a situation where your KPI report helped avoid an issue.

Answer:
My dashboard flagged high GRN delays in one quarter. We investigated and found delayed
vendor acknowledgment. With process correction and vendor training, we reduced delays by
70% in the next month.

Mock Panel Script: KPI Presentation to Management (Assistant

Store Manager)
Setting:
Quarterly Review Meeting
Panel: Operations Head, Plant Manager, Internal Auditor
You: Assistant Store Manager presenting KPI dashboard and performance

🔹 Panel Script:

You:
"Good morning, everyone. I’ll be presenting the store performance KPIs for Q2. We’ve
focused on four core indicators that directly impact production continuity and compliance."
📊 Slide 1: Inventory Accuracy

You:
"We achieved 98.3% accuracy against a target of 97%. This was due to weekly cycle counts
introduced in Zone B, which previously had frequent mismatches."

Operations Head:
"Was there any specific material where the variance was high?"

You:
"Yes, finished bulk packing material had a 3.2% mismatch in May, traced back to barcode
scanning errors. We've since trained the team and improved SOP adherence."

📊 Slide 2: ITR – Inventory Turnover Ratio

You:
"Our ITR improved from 4.5 to 5.2 this quarter. This was driven by tighter procurement
planning and clearance of slow-moving RM."

Plant Manager:
"Did this affect material availability?"

You:
"Not at all. We aligned issue planning with the MRP schedule, ensuring no production halt
occurred."

📊 Slide 3: GRN Timeliness

You:
"GRN processing time reduced from an average of 16 hours to 5 hours. We implemented a
GRN alert system that notifies the store team instantly after gate entry."

📊 Slide 4: Near Expiry %

You:
"We maintained near-expiry inventory under 1%. A monthly report now auto-highlights
materials within 60 days of expiry, allowing early consumption or return."

Internal Auditor:
"Any CAPA raised this quarter?"

You:
"Yes, one. A batch of adhesives had just 10 days shelf life left—missed during inward. The
CAPA includes a pre-inward validation in ERP, now mandatory."

Closing:
"Based on these KPIs, our store performance is on track with no stockouts, minimal
shrinkage, and process improvement visible across functions."
🧪 Scenario-Based Case Study: KPI Trend Prevents Major
Loss
Title: Avoiding Line Shutdown via KPI Monitoring – A Real Case

🎯 Context:

A critical Fastener RM (used daily) was being monitored under the Near Expiry % KPI.
The ERP dashboard auto-flagged this item as "Due for expiry in 20 days."

📈 KPI Trigger:

 KPI Dashboard showed an increase from 0.5% to 2.1% near expiry inventory in the
“Critical Consumables” group.
 On manual check, a batch of fasteners (worth ₹3.5L) was nearing expiry and not
traceable to any active Job Work order.

🛠️Action Taken:

 Store escalated to Planning.

 Job orders were rescheduled to use up the batch within 10 days.
 ERP alert was updated to trigger at 45 days instead of 30.

💡 Outcome:

 Avoided expiry write-off worth ₹3.5L

 Maintained ITR and Inventory Accuracy
 Panel commended the “Preventive KPI Utilization”

Employee Management in Store Operations

Key Elements:

 Gate Log Reconciliation: Daily tally of physical vs ERP outward entries
 Compliance Scorecards: Monthly performance % on key checkpoints
  Vendor Material Traceability: Labeling, shelf life, lot-based GRNs

🧪 Case Study: Shrinkage Identified During Quarterly

Compliance Audit
Scenario: In a routine compliance audit, it was found that:

 5 high-value items (worth ₹2.5 lakhs) were missing.

 ERP showed them as "issued to production", but no Job Card trace existed.

Root Cause:

 ERP access was shared between operators.

 No material issue approval was enforced.
 Gate security wasn’t validating dispatch challans.

Action Plan:

 Introduced Role-based ERP login and digital approval system.

 Retrained staff on SOPs and accountability mapping.
 Introduced Store-Gate ERP sync check before any dispatch.

Result:
No further compliance non-conformity in next two audits. Employee-level accountability
increased.

🎤 Mock Interview Q&A – Store Security & Compliance

Demand Forecasting & Stock Replenishment

🔍 Meaning & Objective:

Demand forecasting is the process of estimating future material requirements based on

historical data, upcoming production plans, lead time, and market trends. Stock
replenishment ensures the right quantity of materials is available at the right time to avoid
stockouts or overstocking.

🧩 Components of Demand Forecasting:

1. Historical Consumption Data

o Analyze past 3–12 months of stock movement.
o Identify high-usage periods and seasonality.
2. Production Plan Alignment
o Match forecast with approved production schedules (weekly/monthly).
o Understand BOM (Bill of Materials) for each product.
3. Lead Time Consideration
o Factor vendor lead time + inspection + internal processing.
4. Safety Stock
o Maintain buffer for critical or long lead-time items.
5. Trend & Exception Analysis
o Sudden surge/dip in demand due to promotions, project delays, etc.

📦 Stock Replenishment Process:

1. Review Inventory Reports

o Run ERP reports for slow/fast movers, critical stock, near expiry.
2. Set Minimum, Maximum & Reorder Levels
o Define these in ERP for auto-alerts.
o Customize based on SKU class (ABC/FSN/VED analysis).
3. Generate Requisition (PR)
o Based on reorder point or forecast consumption.
 oPR → PO → GRN route.
4. Monitor Stock Vs Plan
o Daily/weekly tracking of forecast vs actual consumption.
o Take corrective actions in case of variances.
5. Adjust Forecasts Periodically
o Monthly reviews to revise based on current trends.

🛠️Tools & Techniques Used:

Tool Use
Excel Models Trend analysis, moving average forecast
ERP Alerts Min/Max/ROL configuration
Power BI Dashboard Visualize forecast accuracy, consumption trends
EOQ (Economic Order Quantity) Optimize reorder quantity
ABC/XYZ Analysis Focus on critical & volatile SKUs

🧠 Mock Interview Q&A – Forecasting & Replenishment

❓Q1: How do you forecast demand for store items?

✅A: I use historical issue data, production schedules, and lead times. I cross-check with
planners and apply moving average models. Critical items are buffered with safety stock,
especially those with long lead time or high rejection risk.

❓Q2: What if forecasted demand was wrong and you’re now overstocked?
✅A: I analyze the variance to identify the root cause. If the production plan was canceled or
rescheduled, I reschedule the material usage or transfer to another location. If it’s a slow
mover, I consider return-to-vendor or liquidation options.

❓Q3: What ERP features do you use to automate replenishment?

✅A: I configure Min/Max and Reorder Levels. Based on actual consumption, the ERP
triggers alerts for PR generation. I use custom dashboards to monitor daily stock health and
issue trends.

❓Q4: How do you prevent stockout of critical materials?

✅A: By identifying them through ABC/FSN analysis, setting higher safety stock, and
ensuring real-time tracking through cycle counts. I also follow up closely with vendors for
on-time delivery.

❓Q5: How do you adjust your forecast if production demand changes suddenly?
✅A: I immediately analyze the change impact, adjust PR/POs if not finalized, and
communicate with vendors to expedite or hold. I then revise the forecast model for the month
accordingly.

ABC & XYZ Analysis, EOQ, Reorder Level Setting

ABC Analysis:

 Meaning: Categorizes inventory based on value and consumption.

 o A – High value, low quantity (tight control)
o B – Moderate value and quantity (routine control)
o C – Low value, high quantity (simplified control)
 Use: Helps prioritize resources, audit frequency, and storage strategy.

XYZ Analysis:

 Meaning: Classifies stock based on variability in demand.

o X – Regular demand, low variation
o Y – Moderate variation, somewhat predictable
o Z – Irregular or unpredictable demand
 Use: Helps in setting safety stock and forecasting strategies.

📐 EOQ (Economic Order Quantity):

 Meaning: Ideal quantity to order minimizing total cost of inventory (ordering + holding).
 Formula:

EOQ=2DSHEOQ = \sqrt{\frac{{2DS}}{H}}EOQ=H2DS

o D = Annual demand
o S = Ordering cost per order
o H = Holding cost per unit
 Use: Avoids overstocking and understocking.

🔁 Reorder Level (ROL):

 Meaning: The inventory level at which a new order must be placed to replenish stock before
it runs out.
 Formula:

ROL=LeadTime×AverageDailyUsageROL = Lead Time \times Average Daily

UsageROL=LeadTime×AverageDailyUsage

 Use: Ensures material availability without interruption.

GRN (Goods Receipt Note), MRR (Material Receipt Report), Inspection Process

📦 GRN – Goods Receipt Note:

 Purpose: A document issued when materials are physically received in the store.
 Details: Vendor, PO number, quantity received, date, remarks.
 System Use: ERP/WMS generates GRN which triggers inward entry.

🧾 MRR – Material Receipt Report:

 Purpose: A formal record after inspection is complete.

 Details: Quality status, test results, acceptance/rejection remarks.
 Sign-off: Quality Inspector + Store Manager.

🔍 Inspection Process:
 1. Visual Inspection – Packaging, labeling, damages.
2. Quality Testing – Lab or standard-based checks.
3. Comparison – PO terms vs actual receipt.
4. Approval/Rejection – Send for storage or raise rejection note.

🔍 ABC Analysis – Mock Q&A

Q1. What is ABC analysis and how do you use it in store management?
A1.
ABC analysis helps categorize inventory based on annual consumption value:

 A items are high-value and need strict control and frequent audits.
 B items are moderate value needing periodic monitoring.
 C items are low value with bulk handling.
I use ABC to decide stock audits, order frequency, and storage location priority.

Q2. Can you give a practical example of applying ABC analysis?

A2.
In my previous role, we applied ABC to fasteners, bearings, and tools. We discovered 80% of the
inventory value came from just 15% of the items (A-class), so we implemented barcode tracking and
restricted access, which reduced pilferage and overstocking by 20%.

📈 XYZ Analysis – Mock Q&A

Q3. How does XYZ differ from ABC, and where do you use it?
A3.
XYZ analysis classifies items based on demand consistency.

 X items have predictable, stable demand

 Y items show moderate variation
 Z items are irregular and difficult to forecast
We use XYZ for setting safety stock and in MRP planning. I combine ABC-XYZ to prioritize
safety stock—e.g., ‘AZ’ items need tight control and high buffer.

📐 EOQ – Mock Q&A

Q4. Explain EOQ and how it helps in inventory optimization.

A4.
EOQ (Economic Order Quantity) determines the ideal quantity to order that minimizes ordering and
holding costs. By calculating EOQ, I reduce carrying cost and avoid excess stock. In one instance,
applying EOQ cut inventory holding cost by 15%.

Q5. What happens if EOQ is not followed in a high-consumption store?

A5.
It can lead to either overstocking (tying up capital, risking expiry) or frequent ordering (increased
operational cost). Both disrupt operations and profitability.

🔁 Reorder Level – Mock Q&A

Q6. How do you calculate and maintain Reorder Level (ROL)?
A6.
ROL = Average Daily Usage × Lead Time
I monitor ROL through ERP, which auto-triggers Purchase Requests. I also manually verify ROL for
critical materials weekly, especially if supplier lead time changes.

📦 GRN/MRR/Inspection – Mock Q&A

Q7. What is a GRN and why is it important?

A7.
A GRN is a document generated when material is physically received. It confirms quantity, date, PO
match, and triggers inward entry in ERP. It helps maintain inventory accuracy and traceability.

Q8. What if there's a mismatch in PO vs material received?

A8.
We hold the material, inform procurement, and update ERP with a hold status. We raise an NCR
(Non-Conformance Report) and involve the vendor if needed. GRN is withheld until resolved.

Q9. What is MRR and who approves it?

A9.
MRR (Material Receipt Report) is raised post inspection, capturing test status, acceptance, and
remarks. It is signed by the Quality Inspector and Store In-Charge, and stored in ERP with
traceability.

Q10. Can you share an example where inspection prevented a major loss?
A10.
Yes. Once, during visual inspection, we found rusted bolts in an urgently needed consignment.
Immediate NCR was raised. Since we caught it before GRN/MRR, we saved production downtime
and avoided usage of defective items.
