Welcome to your operations management (OM) course. In this book, we present a state-of-the- art view of the operations function. Operations is an exciting area of management that has a profound effect on productivity. Indeed, few other activities have as much impact on the quality of our lives. The goal of this text is to present a broad introduction to the field of operations in a realistic, practical manner. Even if you are not planning on a career in the operations area, you will likely be working with people in operations. Therefore, having a solid understanding of the role of operations in an organization will be of substantial benefit to you. This book will also help you understand how OM affects society and your life. Certainly, you will better understand what goes on behind the scenes when you attend a concert or major sports event; purchase a bag of Frito-Lay potato chips; buy a meal at an Olive Garden or a Hard Rock Cafe; place an order through Amazon.com; board a flight on Alaska Airlines; or enter a hospital for medical care. More than one and a half million readers of our earlier editions seem to have endorsed this premise.
We welcome comments by email from our North American readers and from students using the International edition, the Indian edition, the Arabic edition, and our editions in Portuguese, Spanish, Turkish, Indonesian, and Chinese. Hopefully, you will find this material useful, interest- ing, and even exciting.
New to This Edition We’ve made significant revisions to this edition, and want to share some of the changes with you.
Five New Video Case Studies Featuring Alaska Airlines In this edition, we take you behind the scenes of Alaska Airlines, consistently rated as one of the top carriers in the country. This fascinating organization opened its doors—and planes— so we could examine leading edge OM in the airlines industry. We observe: the quality pro- gram at Alaska Air (Chapter 6); the process analysis behind the airline’s 20-minute baggage retrieval guarantee (Chapter 7); how Alaska empowers its employees (Chapter 10); the air- line’s use of Lean, 5s, kaizen, and Gemba walks (Chapter 16); and the complexities of sched- uling (Module B).
Our prior editions focused on integrated Video Case Studies for the Orlando Magic basketball team, Frito-Lay, Darden Restaurants, Hard Rock Cafe, Arnold Palmer Hospital, Wheeled Coach Ambulances, and Regal Marine. These Video Case Studies appear in this edition as well, along with the five new ones for Alaska Airlines. All of our videos are created by the authors, with the outstanding coauthorship of Beverly Amer at Northern Arizona University, to explicitly match with text content and terminology.

Creating Your Own Excel Spreadsheets We continue to provide two free decision support software programs, Excel OM for Windows and Mac and POM for Windows, to help you and your students solve homework problems and case studies. These excellent packages are found in MyOMLab and at our text’s Student Download Page.
Many instructors also encourage students to develop their own Excel spreadsheet models to tackle OM issues. With this edition, we provide numerous examples at chapter end on how to do so. “Creating Your Own Excel Spreadsheets” examples now appear in Chapters 1, 2, 4, 8, 12, and 13, Supplement 6, Supplement 7, and Modules A, B, and F. We hope these eleven samples will help expand students’ spreadsheet capabilities.
Video Case Alaska Airlines: 20-Minute Baggage Process—Guaranteed! Alaska Airlines is unique among the nine major U.S. carriers not only for its extensive flight coverage of remote towns throughout Alaska (it also covers the U.S., Hawaii, and Mexico from its pri- mary hub in Seattle). It is also one of the smallest independent airlines, with 10,300 employees, including 3,000 flight attendants and 1,500 pilots. What makes it really unique, though, is its abil- ity to build state-of-the-art processes, using the latest technology, that yield high customer satisfaction. Indeed, J. D. Power and Associates has ranked Alaska Airlines highest in North America for seven years in a row for customer satisfaction.
Alaska Airlines was the first to sell tickets via the Internet, first to offer Web check-in and print boarding passes online, and first with kiosk check-in. As Wayne Newton, Director of System Operation Control, states, “We are passionate about our pro- cesses. If it’s not measured, it’s not managed.”
One of the processes Alaska is most proud of is its baggage han- dling system. Passengers can check in at kiosks, tag their own bags with bar code stickers, and deliver them to a customer service agent at the carousel, which carries the bags through the vast under- ground system that eventually delivers the bags to a baggage han- dler. En route, each bag passes through TSA automated screening and is manually opened or inspected if it appears suspicious. With the help of bar code readers, conveyer belts automatically sort and transfer bags to their location (called a “pier”) at the tarmac level. A baggage handler then loads the bags onto a cart and takes it to Al

Using Software for Productivity Analysis
This section presents three ways to solve productivity problems with computer software. First, you can create your own Excel spreadsheets to conduct productivity analysis. Second, you can use the Excel OM software that comes with this text. Third, POM for Windows is another program that is available with this text .
Program 1.1
Actions Copy C7 to B7, Copy B14 to C14, Copy C15 to B15, and Copy D14 to D15
Create a row for each of the inputs used for the productivity measure. Put the output in the last row.
=C5*C6
=B10/B7
Enter the values for the old system in column B and the new system in Column C.
Productivity = Output/Input
=(C14-B14)/B14=C10/(C8+C9)
X USING EXCEL OM Excel OM is an Excel “add-in” with 24 Operations Management decision support “Templates.” To access the templates, double- click on the Excel OM tab at the top of the page, then in the menu bar choose the appropriate chapter (in this case Chapter 1 ), from either the “Chapter” or “Alphabetic” tab on the left. Each of Excel OM’s 24 modules includes instructions for that particular module. The instructions can be turned on or off via the “instruction” tab in the menu bar.
