What Is Operations Management?
Production is the creation of goods and services
Operations management (OM) is the set of activities that creates value in the form of goods and services by transforming inputs into outputs

Organizing to Produce Goods and Services
Essential functions:
1. Marketing – generates demand
2. Production/operations – creates the product
3. Finance/accounting – tracks how well the organization is doing, pays bills, collects the money

Members of the supply chain collaborate to achieve high levels of customer satisfaction, efficiency and competitive advantage

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

Differences Between Goods and Services
| TABLE 1.3 | ||
| CHARACTERISTICS OF SERVICES | CHARACTERISTICS OF GOODS | |
| Intangible: Ride in an airline seat | Tangible: The seat itself | |
| 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 Challenge
Productivity is the ratio of outputs (goods and services) divided by the inputs (resources such as labor and capital)
The objective is to improve productivity!
Important Note!
Production is a measure of output only and not a measure of efficiency

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%).

Eli Whitney (1800) is credited for the early popularization of interchangeable parts, which was achieved through standardization and quality control. Through a contract he signed with the U.S. government for 10,000 muskets, he was able to command a premium price because of their interchangeable parts.
Frederick W. Taylor (1881), known as the father of scientific management, contributed to personnel selection, planning and scheduling, motion study, and the now popular field of ergo- nomics. One of his major contributions was his belief that management should be much more resourceful and aggressive in the improvement of work methods. Taylor and his colleagues, Henry L. Gantt and Frank and Lillian Gilbreth, were among the first to systematically seek the best way to produce.
Another of Taylor’s contributions was the belief that management should assume more responsibility for:
1. Matching employees to the right job. 2. Providing the proper training. 3. Providing proper work methods and tools. 4. Establishing legitimate incentives for work to be accomplished.

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 significant contribution to the field 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 as contributions from other disciplines, including industrial engineering, statistics, management, analytics, and economics, improve deci- sion 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 specialized glass for iPhones 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 define 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 analyti- cal 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.
