What is Operations Management? Operations management (OM) is defined as the design, operation, and improvement of the systemsthat create and deliver the firm’s primary products and services.
What is a Transformation Process? A transformation process is defined as a user of resources to transform inputs into some desired outputs.

Productivity • Productivity • A measure of the effective use of resources, usually expressed as the ratio of output to input • Productivity ratios are used for • Planning workforce requirements • Scheduling equipment • Financial analysis
Outputs Productiv ity = Inputs Productivity • Partial measures • output/(single input) • Multi-factor measures • output/(multiple inputs) • Total measure • output/(total inputs)
