Why Study OM?Why Study OM?
1. OM is one of three major functions of
any organization, we want to study
how people organize themselves for
productive enterprise
2. We want (and need) to know how
goods and services are produced
3. We want to understand what
operations managers do
4. OM is such a costly part of an
organization

Transformation
The U.S. economic system
transforms inputs to outputs
at about an annual 2.5%
increase in productivity per
year. The productivity
increase is the result of a
mix of capital (38% of 2.5%),
labor (10% of 2.5%), and
management (52% of 2.5%).
