2 MAJOR ASPECTS OF PROCESS MANAGEMENT What: What resources are needed, and in what amounts?
1) Managing a process to meet demand When: When should the work be scheduled?
Where: Where will the work be done?
How: How will the work be done?
Who: Who will do the work?

INTRODUCTION TO OPERATION MANAGEMENT
Operations is what business do. It is the work of managing
the inner workings of a business so it would run smoothly.

SIMILARITIES AND DIFFERENCES BETWEEN PRODUCTION
OF GOODS AND SERVICE OPERATIONS
Production of goods results in tangible output,
anything that we can see or touch.
Delivery of service generally implies an act. Usually
produce intangible products.
Goods are produced and services are performed.
Production of goods and delivery of service are
often different in terms of what (tangible and
intangible) is done but quite similar in terms of
how it is done.

is an absence of variety in a product, service, or
process.
Standardized products are made in large quantities of
identical items.
Standardized service implies that every customer or
item processed receives essentially the same service.
3. Mass customization
This one is a strategy of producing basically
standardized goods or services, but incorporating
some degree of customization in the final product or
service.
Delayed differentiation – is a process of producing,
but not quite completing, a product or service until
customer preferences are known. It is a
postponement tactic.
Modular design – this is a form of standardization in
which component parts are grouped into modules
that are easily replaced or interchanged.

What are two main concerns of inventory
management?
Inventory management is the supervision of
inventories, mainly to keep it in an adequate amount
to meet customer demand and also be cost-effective.
1. level of customer service- having the right goods
available in the right quantity in the right place at the
right time.
2. costs of ordering and carrying inventories- overall
objective of inventory management is to achieve
satisfactory levels of customer service, while keeping
inventory costs within reasonable bounds.
What are the requirements for effective inventory
management?
1. a system keep track of inventory
2. a reliable forecast of demand
3. knowledge of lead time and lead time variability
4. reasonable estimates of holding costs, ordering
costs, shortage costs.
5. a classification system for inventory items.
2 inventory counting systems
1. periodic system- physical count of items in
inventory is made at periodic & fixed intervals in order
to decide how much to order for each item.
2. perpetual inventory system- keeps track of
