- The best way to start understanding the nature of ‘’operations’’ is to look around you
- Everything you can see around you has been produced by an operation
- Every service you consumed today (radio station, bus service, lecture, etc) has also been produced by
an operation
- Everything you buy, sit on, wear, eat and throw away, was created by an operation
Operations management = the activity of managing the resources which are devoted to the production and
delivery of products and services
- Uses resources to appropriately create outputs that fulfill defined market requirements
- But operations can be very different
ITO MODEL
All operations are input-transformation-output processes
SPECTRUM OF PRODUCTS AND SERVICES
Characteristics of goods/products
- Tangible
- Production proceeds consumption, they can be stored
- Transformed resources materials
,Characteristics of services
- Intangible
- Production at the same time as consumption, cannot be stored
- Transformed resources the customers
Spectrum of products and services
- Facilitating products
o Products that are produced by an operation to support its services, e.g., reports prepared by
a consultancy firm, receipts prepared at a shop
- Facilitating services
o Services that are produced by an operation to support its products, e.g., technical advice
provided by an aluminum smelting firm
PROCESS HIERARCHY

needs. They are building blocks of all operations and they form an internal network withing an operation

Creating a typology of operations, based on four dimensions
1. Volume
2. Variety
