Deborah Butler, Caterpillar

Deborah Butler is a certified Master Black Belt, but don’t expect to see her working with Jet Li anytime soon. In fact, her job has little to do with martial arts. Employed by Caterpillar, “the world’s leading manufacturer of construction and mining equipment, diesel and natural gas engines, and industrial gas turbines,” Butler’s Master Black Belt status reflects her expertise in Six Sigma, the process Caterpillar employees use to continually manage, improve, and create processes, products, and services. “Sigma” refers to the maximum number of defects tolerated in production or service delivery; Six Sigma is the highest level of quality control, demanding no more than 3.4 defects per million parts. That means if you were to use Six Sigma in your college career, you would miss only one half of a single question in over four years of test-taking!

Caterpillar was the first corporation to take Six Sigma global, deploying it corporate-wide in 2001 not only to its almost 300 facilities, but also eventually to every dealer and more than 850 key suppliers throughout the world. The corporation hails the process as a key element of its overall operations management, attributing increased profits, improved customer service, and supply-chain efficiency to Six Sigma.

Caterpillar’s more than 300 Master Black Belts lead projects that use Six Sigma and train the company’s approximately 3,300 Black Belts in the principles of the process. Butler is currently in charge of updating and implementing Our Values in Action: Caterpillar’s Worldwide Code of Conduct. Outlining the four core values of integrity, excellence, teamwork, and commitment, the updated code of conduct embodies two important aspects of Caterpillar’s philosophy on Six Sigma.

Sigma is a Greek letter that represents a statistical unit of measurement and defines standard deviation. Caterpillar uses this standard deviation for the number of errors in a product, which equates to 3.4 errors per million. Six Sigma is designed to reduce the number of errors in a process by a step-by-step approach. Caterpillar uses the Six Sigma methodology that utilizes the process of gathering information, analyzing the data, and then making decisions based on the facts. This process ensures that Caterpillar is meeting the requirements of the customer.

Caterpillar recognizes that employees are the heart of any operation. Therefore, Caterpillar employees use Six Sigma to improve as people and as workers as much as to improve the products they produce. The core values, reflected in a series of action statements such as “We put Integrity in action when we compete fairly,” are the product of a yearlong development process involving Butler’s global team. As part of the project research, the team interviewed thousands of Caterpillar employees, from officers of the company to production and hourly workers, for the purpose of, as Butler says, “bringing to the surface the values that have made Caterpillar a successful enterprise, enhancing behavioral expectations, and accurately expressing Caterpillar’s corporate culture.”

Caterpillar is not content simply to produce Our Values in Action and leave it at that, however, and the second aspect of its Six Sigma philosophy is that employees must bring the process to their lives. Butler has worked to inject the code of conduct’s values into employees’ day-to-day work. If an employee writes about safety-related changes, for example, she would not just list the changes. Instead, she might write first: “According to Our Values In Action, we put Commitment in action when we protect the health and safety of others and ourselves. As such, we are implementing the following changes. . . .” In this way, the code becomes a living part of corporate culture, a critical component of operations management.

Nearly every type of business organization needs to find the most efficient and effective methods of producing the goods or services it sells to its customers. Technological advances, ongoing competition, and consumer expectations force companies to rethink where, when, and how they will produce products or services.

Manufacturers have discovered that it is no longer enough to simply push products through the factory and onto the market. Consumers demand high quality at reasonable prices. They also expect manufacturers to deliver products in a timely manner. Firms that can’t meet these expectations often face strong competition from businesses that can. To compete, many manufacturers are streamlining how they make their products—by automating their factories, developing new production processes, focusing on quality-control techniques, and improving relationships with suppliers.

Service organizations also face challenges. Their customers are demanding better service, shorter waiting periods, and more individualized attention. Like manufacturers, service companies are using new methods to deliver what their customers need and want. Banks, for example, are using technology such as online banking and mobile apps to make their services more accessible to customers. Colleges offer online courses to accommodate the schedules of working students. Tax services file tax returns via the cloud.

This chapter examines how manufacturers and service firms manage and control the creation of products and services. We’ll discuss production planning, including the choices firms must make concerning the type of production process they will use; the location where production will occur; the design of the facility; and the management of resources needed in production. Next, we’ll explain routing and scheduling, two critical tasks for controlling production and operations efficiency. Then we will look at how firms can improve production and operations by employing quality management and lean-manufacturing techniques. Finally, we will review some of the trends affecting production and operations management.
