OM
Exam Preparation Note for Operations Management
1. Define Operations Management
Definition:
Operations Management (OM) is the field of management concerned with designing,
overseeing, and controlling production processes and redesigning business operations in the
production of goods or services.
o It ensures that business operations are efficient, using as few resources as possible.
o It also ensures effectiveness in meeting customer requirements.
Key Elements of Operations Management:
o Planning, organizing, and supervising the production process.
o Aligning resources, technology, and labor to achieve organizational goals.
2. Describe Operations Management, Its Scope, and Activities
Scope of Operations Management:
1. Product Design:
Focus on creating goods or services that satisfy customer needs and provide
competitive advantages.
2. Process Design:
Deciding the sequence of operations and methods to achieve production
objectives efficiently.
3. Supply Chain Management:
Overseeing materials, information, and financial flows from suppliers to end
customers.
4. Inventory Management:
Ensuring optimal stock levels to avoid overstocking or stockouts.
5. Quality Management:
Maintaining product and process quality standards.
Activities of Operations Management:
o Planning: Setting production objectives, forecasting demand, and resource allocation.
o Organizing: Structuring teams, resources, and workflows.
o Coordinating: Synchronizing activities across departments and supply chains.
o Controlling: Monitoring performance metrics, costs, and schedules.
3. Understand Operations Strategy and Competitiveness
Operations Strategy:
A plan that determines how an organization’s operational resources contribute to achieving
business objectives.
Competitive Priorities in Operations Strategy:
1. Cost Leadership:
Minimizing costs to offer competitive prices.
Examples: Efficient manufacturing processes, economies of scale.
2. Quality:
Producing high-quality goods and services to meet customer expectations.
Examples: Total Quality Management (TQM), Six Sigma.
3. Flexibility:
Ability to adjust to changes in product design, volume, or demand.
Example: Customizable products or modular production systems.
4. Delivery:
Ensuring on-time delivery of goods and services.
Example: Just-in-Time (JIT) inventory systems.
Link Between Operations Strategy and Competitiveness:
o An effective operations strategy enables an organization to deliver value to customers
while maintaining a competitive edge in cost, quality, and innovation.
4. Describe Decisions in Designing and Controlling the Operations System
Decisions in Operations System Design:
1. Product and Service Design:
Deciding product features, quality standards, and market requirements.
Example: Launching a product with eco-friendly packaging.
2. Process Design:
Selecting the production process (e.g., batch, continuous flow, job shop).
3. Capacity Planning:
Determining production capacity needed to meet demand.
Example: Expanding production lines during peak seasons.
4. Technology Selection:
Deciding on machinery, software, and automation tools.
Example: Investing in AI-driven inventory management systems.
5. Facility Location and Layout:
Choosing where to locate a facility and how to layout equipment and
workstations.
Decisions in Controlling the Operations System:
o Scheduling: Determining timelines for production activities.
o Inventory Control: Managing stock levels to avoid shortages or surpluses.
o Quality Assurance: Monitoring and maintaining product quality.
o Cost Control: Ensuring expenses stay within budget.
5. Understand Facility Location and Layout
Facility Location:
o Refers to choosing the optimal geographical location for production or service delivery.
o Factors to Consider:
Proximity to Customers: Minimizing transportation costs and improving delivery
times.
Infrastructure: Availability of transportation, utilities, and communication
networks.
Labor Availability: Skilled workforce at competitive wages.
Government Policies: Tax incentives, regulations, and subsidies.
Facility Layout:
o Refers to the arrangement of machines, workstations, and resources within a facility.
o Types of Layouts:
1. Process Layout: Resources are grouped based on similar processes.
Suitable for job shops or customized production.
2. Product Layout: Resources are arranged in a sequence to produce standardized
goods.
Example: Assembly lines for cars.
3. Fixed-Position Layout: The product remains stationary, and resources move to
it.
Example: Construction sites, shipbuilding.
4. Hybrid Layout: Combines elements of process and product layouts.
Example: Supermarkets with both departments and aisles.
6. Discuss Aggregate Planning
Definition:
Aggregate planning determines the overall production levels, workforce, and inventory
requirements to meet anticipated demand over a medium-term horizon (3-18 months).
Objectives of Aggregate Planning:
o Minimize production costs.
o Balance supply and demand.
o Maintain stable workforce and production rates.
Strategies for Aggregate Planning:
1. Chase Strategy: Adjust production rates to match demand.
Example: Hiring or laying off workers during demand fluctuations.
2. Level Strategy: Maintain a steady production rate and workforce.
Example: Building inventory during low demand periods to meet peak season
demand.
3. Hybrid Strategy: Combines chase and level strategies for flexibility and cost-efficiency.
Tools for Aggregate Planning:
o Linear Programming: Optimize resources under constraints.
o Simulation Models: Test different scenarios to identify the best plan.
o Forecasting Techniques: Use historical data to predict future demand.
7. Apply Selected Quantitative Tools
Quantitative Tools for Operations Management:
1. Forecasting Models:
Time Series Analysis: Predicts demand using historical patterns.
Exponential Smoothing: Assigns more weight to recent data for demand
forecasting.
2. Linear Programming:
Solves optimization problems like maximizing profit or minimizing cost.
Example: Determining the optimal product mix given resource constraints.
3. Queuing Theory:
Optimizes service processes by analyzing customer wait times and resource
utilization.
Example: Reducing waiting times in hospitals or call centers.
4. Economic Order Quantity (EOQ):
Calculates the optimal order size to minimize inventory holding and ordering
costs.
5. ABC Analysis:
Categorizes inventory items into three groups based on value and usage
frequency:
A: High-value, low-quantity items.
B: Moderate-value items.
C: Low-value, high-quantity items.
6. Statistical Quality Control:
Uses control charts to monitor processes and ensure product quality.
Example: Detecting defects in production lines.
