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

Matching employees to right job
Providing the proper training
Establishing legitimate incentives for work to be accomplished
*
Applied efficiency methods to their home and 12 children!

Produced and consumed simultaneously: Beauty salon produces a haircut that is consumed as it is produced
Product can usually be kept in inventory (beauty care products)
Unique: Your investments and medical care are unique
Similar products produced (iPods)
High customer interaction: Often what the customer is paying for (consulting, education)
Limited customer involvement in production
Inconsistent product definition: Auto Insurance changes with age and type of car
Product standardized (iPhone)
Often knowledge based: Legal, education, and medical services are hard to automate
Standard tangible product tends to make automation feasible
Services dispersed: Service may occur at retail store, local office, house call, or via internet.
Product typically produced at a fixed facility
Quality may be hard to evaluate: Consulting, education, and medical services
Many aspects of quality for tangible products are easy to evaluate (strength of a bolt)
Reselling is unusual: Musical concert or medical care
Product often has some residual value

Productivity is the ratio of outputs (goods and services) divided by the inputs (resources such as labor and capital)

services
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%).

Improving Productivity at Starbucks
A team of 10 analysts continually look for ways to shave time. Some improvements:
Stop requiring signatures on credit card purchases under $25
Saved 8 seconds per transaction
Change the size of the ice scoop
Saved 14 seconds per drink
New espresso machines

10 PART 1 | INTRODUCTION TO OPERATIONS MANAGEMENT
By 1913, Henry Ford and Charles Sorensen combined what they knew about standardized parts with the quasi-assembly lines of the meatpacking and mail-order industries and added the revolutionary concept of the assembly line, where men stood still and material moved.
Quality control is another historically signi!cant contribution to the !eld of OM. Walter Shewhart (1924) combined his knowledge of statistics with the need for quality control and provided the foundations for statistical sampling in quality control. W. Edwards Deming (1950) believed, as did Frederick Taylor, that management must do more to improve the work environ- ment and processes so that quality can be improved.
Operations management will continue to progress with contributions from other disci- plines, including industrial engineering, statistics, management, and economics, contribute to improved models and decision making.
Innovations from the physical sciences (biology, anatomy, chemistry, physics) have also contributed to advances in OM. These innovations include new adhesives, faster integrated circuits, gamma rays to sanitize food products, and higher-quality glass for plane and plasma TVs. Innovation in products and processes often depends on advances in the physical sciences.
Especially important contributions to OM have come from information technology, which we de!ne as the systematic processing of data to yield information. Information technology—with wireless links, Internet, and e-commerce—is reducing costs and accelerating communication.
Decisions in operations management require individuals who are well versed in analytical tools, in information technology, and often in one of the biological or physical sciences. In this textbook, we look at the diverse ways a student can prepare for a career in operations management.
