Introduction
Operations management is the management of anorganizations productive resources or its production
system.
A production system takes inputs and converts them
into outputs.
The conversion process is the predominant activity of
a production system.
The primary concern of an operations manager is theactivities of the conversion process.

The Industrial Revolution
The industrial revolution developed in England in the1700s.
The steam engine, invented by James Watt in 1764,
largely replaced human and water power for factories.
Adam Smiths The Wealth of Nationsin 1776 touted
the economic benefits of the specialization of labor.
Thus the late-1700s factories had not only machine
power but also ways of planning and controlling thetasks of workers.

The Industrial Revolution
The industrial revolution spread from England toother European countries and to the United Sates.
In 1790 an American, Eli Whitney, developed the
concept of interchangeable parts.
The first great industry in the US was the textile
industry.
In the 1800s the development of the gasoline engine
and electricity further advanced the revolution. By the mid-1800s, the old cottage system of
production had been replaced by the factory system.

Post-Civil War Period
During the post-Civil War period great expansion ofproduction capacity occurred.
By post-Civil War the following developments set the
stage for the great production explosion of the 20th
century:
increased capital and production capacity
the expanded urban workforce
new Western US markets an effective national transportation system

Scientific Management
Frederick Taylor is known as the father of scientificmanagement. His shop system employed these steps:
Each workers skill, strength, and learning ability
were determined.
Stopwatch studies were conducted to precisely set
standard output per worker on each task.
Material specifications, work methods, and routing
sequences were used to organize the shop. Supervisors were carefully selected and trained.
Incentive pay systems were initiated.

Operations Research
During World War II, enormous quantities ofresources (personnel, supplies, equipment, ) had to
be deployed.
Military operations research (OR) teams were formed
to deal with the complexity of the deployment.
After the war, operations researchers found their way
back to universities, industry, government, and
consulting firms. OR helps operations managers make decisions when
problems are complex and wrong decisions are
costly.

The Service Revolution
The creation of services organizations acceleratedsharply after World War II.
Today, more than two-thirds of the US workforce is
employed in services.
About two-thirds of the US GDP is from services.
There is a huge trade surplus in services.
Investment per office worker now exceeds the
investment per factory worker.
Thus there is a growing need for service operations
management.

The Computer Revolution
Explosive growth of computer and communicationtechnologies
Easy access to information and the availability of
more information
Advances in software applications such as Enterprise
Resource Planning (ERP) software
Widespread use of email
More and more firms becoming involved in E-Business using the Internet
Result: faster, better decisions over greater distances

Production as an Organization Function
US companies cannot compete with marketing,finance, accounting, and engineering alone.
We focus on OM as we think of global
competitiveness, because that is where the vast
majority of a firms workers, capital assets, and
expenses reside.
To succeed, a firm must have a strong operations
function teaming with the other organizationfunctions.

Strategic Decisions
These decisions are of strategic importance and havelong-term significance for the organization.
Examples include deciding:
the design for a new products production process
where to locate a new factory
whether to launch a new-product development plan

Operating Decisions
These decisions are necessary if the ongoingproduction of goods and services is to satisfy market
demands and provide profits.
Examples include deciding:
how much finished-goods inventory to carry
the amount of overtime to use next week
the details for purchasing raw material next month

Control Decisions
These decisions concern the day-to-day activities ofworkers, quality of products and services, production
and overhead costs, and machine maintenance.
Examples include deciding:
labor cost standards for a new product
frequency of preventive maintenance
new quality control acceptance criteria

What Controls the Operations System?
Information about the outputs, the conversions, andthe inputs is fed back to management.
This information is matched with managements
expectations
When there is a difference, management must take
corrective action to maintain control of the system
