Introduction
• Operations management (OM): the management of an organization’s productive resources or its production system.
• Production system: process that converts inputs into finished goods & services.
• Conversion process: the predominant activity of a production system.
• Primary concern of an operations manager: activities of the conversion process.

Historical Milestones in OM
• The Industrial Revolution • Post-Civil War Period • Scientific Management • Human Relations and Behaviorism • Operations Research • The Service Revolution
The Industrial Revolution
• Industrial Revolution the 1700s.
developed in England in • Steam engine, invented by James Watt in 1764, largely replaced human and water power for factories.
• Adam Smith’s
The Wealth of Nations
(1776) touted economic benefits of Specialization of Labor.
• By late-1700s factories had not only machine power but also ways of planning and controlling tasks of workers.
The Industrial Revolution
• Industrial revolution spread from england to other European countries & to united states.
• In 1790 an American, Eli Whitney, developed concept of interchangeable parts • First great industry in us was textile industry.
• In 1800s development of gasoline engine & electricity further advanced revolution • By mid-1800s, old cottage system production had been replaced by of factory system
Post-Civil War Period
• During post-Civil War period great expansion of production capacity occurred.
• By post-Civil War the following developments set stage for great production explosion of 20th century: – Increased capital and production capacity – Expanded urban workforce – New western US markets – Effective national transportation system
Scientific Management Frederick Winslow Taylor
• Frederick Winslow Taylor known as father of scientific management . His shop system employed these steps: – Each worker’s skill, strength, & learning ability were determined.
– Stopwatch studies were conducted to precisely set standard output per worker on each task.
– Material specifications, work methods, & routing sequences were used to organize shop.
– Supervisors were carefully selected & trained.
– Incentive pay systems were initiated.
Scientific Management Henry Ford
• In 1920s, Ford Motor Company’s operation embodied key elements of scientific management: – Standardized product designs – Mass production – Low manufacturing costs – Mechanized assembly lines – Specialization of labor – Interchangeable parts
Human Relations and Behavioralism
• In 1927-1932 period, researchers in the hawthorne studies realized that human factors were affecting production.
• Researchers and managers alike were recognizing that psychological & sociological factors affected production.
• From work of behavioralists came a gradual change in way managers thought about & treated workers.
Operations Research
• During World War II, enormous quantities of resources (personnel, supplies, equipment, …) had to be deployed.
• Military operations research (OR) teams were formed to deal with complexity of deployment.
• After war, operations researchers found their way back to universities, industry, government, & consulting firms.
• OR helps operations managers make decisions when problems are complex & wrong decisions are costly.
Example of Use of Operations Research

The Service Revolution
• The creation of services organizations accelerated sharply after World War II.
• Today, more than 2 / 3 of US workforce is employed in services.
• About 2 / 3 of US GDP is from services.
• There is a huge trade surplus in services.
• Investment per office worker now exceeds investment per factory worker.
• Thus there is a growing need for service operations management.
Today's Factors Affecting OM
• Global competition • US quality, customer service, & cost challenges • Computers & advanced production technology • Growth of US service sector • Scarcity of production resources • Issues of social responsibility
The Computer Revolution
• Explosive growth of computer & communication technologies • Easy access to information & availability of more information • Advances in software applications such as enterprise resource planning (ERP) software • Widespread use of email • More & more firms becoming involved in e business using internet • Result: faster, better decisions over greater distances

Decision Making in OM
• Strategic Decisions • Operating Decisions • Control Decisions
Strategic Decisions
• These decisions are of strategic importance & have long-term significance for the organization.
• Examples include deciding: – Design for a new product’s production process – Where to locate a new factory – Whether to launch a new-product development plan
Operating Decisions
• These decisions are necessary if ongoing production of goods and services is to satisfy market demands & provide profits.
• Examples include deciding: – How much finished-goods inventory to carry – Amount of overtime to use next week – Details for purchasing raw material next month
Control Decisions
• These decisions concern day-to-day activities of workers, quality of products & services, production & overhead costs, & 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 outputs, conversions, and inputs is fed back to management.
• This information is matched with management’s expectations • When there is a difference, management must take corrective action to maintain control of the system
Continuum of Characteristics of Manufacturing & Service Organizations

International Markets
•Large Facilities •Capital Intensive •Quality Easily Measured •Intangible, Perishable Product •Output Cannot Be Inventoried •High Customer Content •Short Response Time •Local Markets •Small Facilities •Labor Intensive •Quality Not Easily Measured
What Is a Process?
• Process—any activity or group of activities that take one or more inputs, transforms and adds value to them, & provides one or more outputs to customers – External customers – Internal customers
