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.

P USING POM FOR WINDOWS POM for Windows is decision support software that includes 24 Operations Management modules. The modules are accessed by double-clicking on Module in the menu bar, and then double-clicking on the appropriate (in this case Productivity ) item. Instructions are provided for each module just below the menu bar.

CREATING YOUR OWN EXCEL SPREADSHEETS Program 1.1 illustrates how to build an Excel spreadsheet for the data in Example 2.

Expanding and Reordering Our Set of Homework Problems We believe that a vast selection of quality homework problems, ranging from easy to challeng- ing (denoted by one to four dots), is critical for both instructors and students. Instructors need a broad selection of problems to choose from for homework, quizzes, and exams—without reus- ing the same set from semester to semester. We take pride in having more problems—by far, with 807—than any other OM text. We added dozens of new problems this edition. The following table illustrates the selection by chapter.

Further, with the majority of our adopters now using the MyOMLab learning system in their classes, we have reorganized all the homework problems—both those appearing in the printed text, as well as the Additional Homework Problems that are available in MyOMLab—by topic heading. We are identifying all problems by topic (see the following example).

The list of all problems by topic also appears at the end of each boxed example, as well as in the Rapid Review that closes each chapter. These handy references should make it easier to assign problems for homework, quizzes, and exams. A rich set of assignable problems and cases makes the learning experience more complete and pedagogically sound.

CHAPTER 5 | DESIGN OF GOODS AND SERVICES 187

Problems 5.4–5.8 relate to Product Development

• • 5.4 Construct a house of quality matrix for a wrist- watch. Be sure to indicate specific customer wants that you think the general public desires. Then complete the matrix to show how an operations manager might identify specific attributes that can be measured and controlled to meet those customer desires.

• • 5.5 Using the house of quality, pick a real product (a good or service) and analyze how an existing organization satis- fies customer requirements.

• • 5.6 Prepare a house of quality for a mousetrap.

• • 5.7 Conduct an interview with a prospective purchaser of a new bicycle and translate the customer’s wants into the specific hows of the firm.

• • • • 5.8 Using the house of quality sequence, as described in Figure 5.4 on page 169, determine how you might deploy resources to achieve the desired quality for a product or service whose production process you understand.

Problems 5.9–5.17 relate to Defining a Product

• • 5.9 Prepare a bill of material for (a) a pair of eyeglasses and its case or (b) a fast-food sandwich (visit a local sandwich

Problems 5.21–5.28 relate to the Application of Decision Trees to Product Design

• • 5.21 The product design group of Iyengar Electric Supplies, Inc., has determined that it needs to design a new series of switches. It must decide on one of three design strategies. The market forecast is for 200,000 units. The better and more sophisticated the design strategy and the more time spent on value engineering, the less will be the variable cost. The chief of engineering design, Dr. W. L. Berry, has decided that the following costs are a good estimate of the initial and variable costs connected with each of the three strategies: a) Low-tech: A low-technology, low-cost process consisting of

hiring several new junior engineers. This option has a fixed cost of $45,000 and variable-cost probabilities of .3 for $.55 each, .4 for $.50, and .3 for $.45.

b) Subcontract: A medium-cost approach using a good outside design staff. This approach would have a fixed cost of $65,000 and variable-cost probabilities of .7 of $.45, .2 of $.40, and .1 of $.35.

c) High-tech: A high-technology approach using the very best of the inside staff and the latest computer-aided design technol- ogy. This approach has a fixed cost of $75,000 and variable- cost probabilities of .9 of $.40 and .1 of $.35.

What is the best decision based on an expected monetary value (EMV) criterion? ( Note: We want the lowest EMV, as we are dealing with costs in this problem.) PX

Jay, Barry, and Chuck’s OM Blog As a complement to this text, we have created a companion blog, with coordinated features to help teach the OM course. There are teaching tips, highlights of OM items in the news (along with class discussion questions and links), video tips, guest posts by instructors using our text, sample OM syllabi from dozens of colleges, and much more—all arranged by chapter. To learn more about any chapter topics, visit www.heizerrenderOM.wordpress.com . As you prepare your lectures and syllabus, scan our blog for discussion ideas, teaching tips, and classroom exercises.

Lean Operations In previous editions, we sought to explicitly differentiate the concepts of just-in-time, Lean, and Toyota Production System in Chapter 16. However, there is significant overlap and interchangea- bility among those three concepts, so we have revised Chapter 16 to incorporate the three concepts into an overall concept of “Lean.” The chapter suggests that students view Lean as a comprehen- sive integrated operations strategy that sustains competitive advantage and results in increased returns to all stakeholders.

Chapter-by-Chapter Changes To highlight the extent of the revisions in this edition, here are a few of the changes, on a chapter- by-chapter basis.

Chapter 1 : Operations and Productivity We updated Table 1.4 to reflect employment in various sectors and expanded our discussion of Lean operations. Our new case, Uber Technologies, introduces productivity by discussing the dis- ruptive nature of the Uber business model. In addition, there is a new “Creating Your Own Excel Spreadsheets” example for both labor productivity and multifactor productivity.

Chapter 2 : Operations Strategy in a Global Environment We have updated Figure 2.1 to better reflect changes in the growth of world trade and Figure 2.5 to reflect product life cycle changes. The Minute Lube case has been revised as Rapid Lube. Example 1 (National Architects) has been expanded to clarify factor rating calculations and is also demonstrated with a “Creating Your Own Excel Spreadsheets” presentation.

Chapter 3 : Project Management We rewrote and updated the Bechtel Global Company Profile and added a new section on well- defined projects with the “agile” and “waterfall” approaches. There are two new OM in Action boxes: “Agile Project Management at Mastek,” and “Behind the Tour de France.”

Chapter 4 : Forecasting We created a new table comparing the MAD, MSE, and MAPE forecasting error measures. There is also a new OM in Action box called “NYC’s Potholes and Regression Analysis.”

Chapter 5 : Design of Goods and Services We expanded our treatment of concurrent engineering and added two new discussion questions. Solved Problem 5.1 has been revised.

Supplement 5: Sustainability in the Supply Chain We wrote a new introductory section on Corporate Social Responsibility. There is also a new OM in Action box called “Blue Jeans and Sustainability” and 10 new homework problems.

Chapter 6 : Managing Quality We added new material to expand our discussion of Taguchi’s quality loss function. There is a new sec- tion on SERVQUAL, and a new video case study, “Quality Counts at Alaska Airlines,” appears here.

Supplement 6: Statistical Process Control We added a figure on the relationship between sample size and sampling distribution. We also added raw data to Examples S2 and S3 to illustrate how ranges are computed. There is a new Excel spreadsheet to show students how to make their own c -chart, and we have added three new homework problems.

Chapter 7 : Process Strategy We wrote a new section on machine technology and additive manufacturing. There are two new discussion questions and three new homework problems. Our second new video case study is called “Alaska Airlines: 20-Minute Baggage Process—Guaranteed!”

Supplement 7: Capacity and Constraint Management We added a new Table S7.1, which compares and clarifies three capacity measurements, with an example of each. There is a new treatment of expected output and actual output in Example S2. The discussion of bottleneck time versus throughput time has also been expanded. Example S3, capacity analysis with parallel processes, has been revised. We have also added a new “Creating Your Own Excel Spreadsheets” example for a break-even model. Finally, we updated the Arnold Palmer Hospital capacity planning case with recent data.

Chapter 8 : Location Strategies We added two new OM in Action boxes: “Iowa—Home of Corn and Facebook” and “Denmark’s Meat Cluster.” We changed the notation for the center-of-gravity model to simplify the equa- tion and provided a new “Creating Your Own Excel Spreadsheets” presentation for the center-of- gravity example.

Chapter 9 : Layout Strategies We created a new Muther grid for office relationship charting and added a spread of five layouts showing how offices have evolved over time. There is a new OM in Action box called “Amazon Lets Loose the Robots,” and there is a new graphic example of Proplanner’s Flow Path Calculator. We have included a formula for idle time as a second measure of balance assignment efficiency and added new technology issues to the Arnold Palmer Hospital video case.

Chapter 10 : Human Resources, Job Design, and Work Measurement We added a new OM in Action box, “The Missing Perfect Chair,” and revised the Operations Chart as a service example. Our third new video case study is “The ‘People’ Focus: Human Resources at Alaska Airlines.”

Chapter 11 : Supply Chain Management We added “outsourcing” as a supply chain risk in Table 11.3.

Supplement 11: Supply Chain Management Analytics We added a major section on the topic of Warehouse Storage, with a new model for allocating inven- tory to storage locations. There is a new discussion question and three new homework problems.

Chapter 12 : Inventory Management New Programs 12.1 and 12.2 illustrate “Creating Your Own Excel Spreadsheets” for both the production run model and the single-period inventory model. The Excel function NORMSINV is introduced throughout the chapter. The Quantity Discount Model section is totally rewritten to illustrate the feasible solution shortcut. Solved Problem 12.5 is likewise redone with the new approach.

Chapter 13 : Aggregate Planning and S&OP We added a new OM in Action box, “Revenue Management Makes Disney the ‘King’ of the Broadway Jungle.” We also provided a new “Creating Your Own Excel Spreadsheets” example for the transportation method for aggregate planning, using the Solver approach.

Chapter 14 : Material Requirements Planning (MRP) and ERP The MRP II example now includes greenhouse gasses.

Chapter 15 : Short-Term Scheduling We begin this chapter with a new Global Company Profile featuring Alaska Airlines and the scheduling issues it faces in its northern climate. We have added two new graphics to help illus- trate Forward and Backward Scheduling. There is also a new section called Performance Criteria, detailing how the choice of priority rule depends on four quantifiable criteria. We now explicitly define the performance criteria for sequencing jobs as separate numbered equations. Also, we provide an explicit formula for job lateness. There is a new OM in Action box called “Starbucks’ Controversial Scheduling Software.”

Chapter 16 : Lean Operations This chapter saw a major reorganization and rewrite with an enhanced focus on Lean operations. There is more material on supplier partnerships and building lean organizations. A new OM in Action box describes the use of kaizen at San Francisco General Hospital, and we have added a new video case study called “Lean Operations at Alaska Airlines.”

Chapter 17 : Maintenance and Reliability There are no major changes in this chapter.

Module A: Decision-Making Tools We added a discussion of “big data” and a new “Creating Your Own Excel Spreadsheets” example on how to evaluate a decision table.

Module B: Linear Programming There is a new section on integer and binary programming, two new homework problems, and a new video case study called “Using LP to Meet Scheduling Challenges at Alaska Airlines.” The corner point method is now covered before the iso-profit line approach.

Module C: Transportation Models There are no major changes to Module C.

Module D: Waiting-Line Models The limited population model (Model D) has been replaced by the finite population model, M/M/1 with finite source. This standardizes the queuing notation to match the M/M/1, M/M/s, and M/D/1. We have also expanded the coverage of Little’s Law and added six new homework problems.

Module E: Learning Curves There are no major changes to Module E.

Module F: Simulation We added a new “Creating Your Own Excel Spreadsheets” example for a simulation problem.

Instructor’s Solutions Manual The Instructor’s Solutions Manual, written by the authors, contains the answers to all of the dis- cussion questions, Ethical Dilemmas , Active Models, and cases in the text, as well as worked-out solutions to all the end-of-chapter problems, additional homework problems, and additional case studies.

PowerPoint Presentations An extensive set of PowerPoint presentations, created by Professor Jeff Heyl of Lincoln University, is available for each chapter. With well over 2,000 slides, this set has excellent color and clarity.

Test Bank / TestGen® Computerized Test Bank The test bank, updated by James Roh, contains a variety of true/false, multiple-choice, short-answer, and essay questions, along with a selection of written problems, for each chapter. Test questions are annotated with the following information:

◆ Diffi culty level ◆ Type: multiple-choice, true/false, short-answer, essay, problem ◆ Learning objective ◆ AACSB (see the description that follows)

TestGen®, Pearson Education’s test-generating software, is PC/MAC compatible and preloaded with all the test bank questions. The test program permits instructors to edit, add, and delete ques- tions from the test bank to create customized tests.

The Association to Advance Collegiate Schools of Business (AACSB)

The test bank has connected select questions to the general knowledge and skill guidelines found in the AACSB Assurance of Learning standards.

AACSB is a not-for-profit corporation of educational institutions, corporations, and other organizations devoted to the promotion and improvement of higher education in business admin- istration and accounting. A collegiate institution offering degrees in business administration or accounting may volunteer for AACSB accreditation review. The AACSB makes initial accredi- tation decisions and conducts periodic reviews to promote continuous quality improvement in management education. Pearson Education is a proud member of the AACSB and is pleased to provide advice to help you apply AACSB assurance of learning standards.

What are AACSB assurance of learning standards? One of the criteria for AACSB accredita- tion is quality of the curricula. Although no specific courses are required, the AACSB expects a curriculum to include learning experiences in the following areas:

◆ Written and oral communication ◆ Ethical understanding and reasoning ◆ Analytical thinking ◆ Information technology ◆ Interpersonal relations and teamwork ◆ Diverse and multicultural work environments ◆ Refl ective thinking ◆ Application of knowledge

Questions that test skills relevant to these guidelines are appropriately tagged. For example, a question regarding clothing manufactured for U.S. firms by 10-year olds in Asia would receive the Ethical understanding and reasoning tag.

Tagged questions help you measure whether students are grasping the course content that aligns with the AACSB guidelines noted. In addition, the tagged questions may help instructors identify potential applications of these skills. This in turn may suggest enrichment activities or other educational experiences to help students achieve these skills.

In addition, we appreciate the wonderful people at Pearson Education who provided both help and advice: Stephanie Wall, our superb editor-in-chief; Lenny Ann Kucenski, our dynamo mar- keting manager; Linda Albelli, our editorial assistant; Courtney Kamauf and Andra Skaalrud for their fantastic and dedicated work on MyOMLab; Jeff Holcomb, our project manager team lead; Claudia Fernandes, our program manager; Jacqueline Martin, our senior project manager; and Heidi Allgair, our project manager at Cenveo® Publisher Services. We are truly blessed to have such a fantastic team of experts directing, guiding, and assisting us.

In this edition, we were thrilled to be able to include one of the country’s premier airlines, Alaska Airlines, in our ongoing Video Case Study series. This was possible because of the wonderful efforts of COO/EVP-Operations Ben Minicucci, and his superb management team. This included John Ladner (Managing Director, Seattle Station Operations), Wayne Newton (Managing Director, Station Operations Control), Mike McQueen (Director, Schedule Planning), Chad Koehnke (Director, Planning and Resource Allocation), Cheryl Schulz (Executive Assistant to EVP Minicucci), Jeffrey Butler (V.P. Airport Operations & Customer Service), Dan Audette (Manager of Operations Research and Analysis), Allison Fletcher (Process Improvement Manager), Carlos Zendejas (Manager Line-Flying Operations, Pilots), Robyn Garner (Flight Attendant Trainer), and Nikki Meier and Sara Starbuck (Process Improvement Facilitators). We are grateful to all of these fine people, as well as the many others that participated in the develop- ment of the videos and cases during our trips to the Seattle headquarters.

We also appreciate the efforts of colleagues who have helped to shape the entire learning pack- age that accompanies this text. Professor Howard Weiss (Temple University) developed the Active Models, Excel OM, and POM for Windows software; Professor Jeff Heyl (Lincoln University) created the PowerPoint presentations; and Professor James Roh (Rowan University) updated the test bank. Beverly Amer (Northern Arizona University) produced and directed the video series; Professors Keith Willoughby (Bucknell University) and Ken Klassen (Brock University) contrib- uted the two Excel-based simulation games; and Professor Gary LaPoint (Syracuse University) developed the Microsoft Project crashing exercise and the dice game for SPC. We have been fortu- nate to have been able to work with all these people.

We wish you a pleasant and productive introduction to operations management.

Operations managers throughout the world are producing products every day to provide for the well-being of society. These products take on a multitude of forms. They may be washing machines at Whirlpool, motion pictures at DreamWorks, rides at Disney World, or food at Hard Rock Cafe. These firms produce thousands of complex products every day—to be

delivered as the customer ordered them, when the customer wants them, and where the cus-

tomer wants them. Hard Rock does this for over 35 million guests worldwide every year. This is a

challenging task, and the operations manager’s job, whether at Whirlpool, DreamWorks, Disney,

or Hard Rock, is demanding.

Orlando-based Hard Rock Cafe opened its first restau-

rant in London in 1971, making it over 45 years old and the

granddaddy of theme restaurants. Although other theme

restaurants have come and gone, Hard Rock is still going

strong, with 150 restaurants in more than 53 countries—and

new restaurants opening each year. Hard Rock made its

name with rock music memorabilia, having started when Eric

Clapton, a regular customer, marked his favorite bar stool

by hanging his guitar on the wall in the London cafe. Now

Hard Rock has 70,000 items and millions of dollars invested

in memorabilia. To keep customers coming back time and

again, Hard Rock creates value in the form of good food and

entertainment.

The operations managers at Hard Rock Cafe at Uni-

versal Studios in Orlando provide more than 3,500 custom

products—in this case meals—every day. These products

are designed, tested, and then analyzed for cost of

Lots of work goes into designing, testing, and costing meals. Then suppliers deliver quality products on time, every time, for well-trained cooks to prepare quality meals. But none of that matters unless an enthusiastic waitstaff, such as the one shown here, holding guitars previously owned by members of U2, is doing its job.

Efficient kitchen layouts, motivated personnel, tight schedules, and the right ingredients at the right place at the right time are required to delight the customer.

ingredients, labor requirements, and customer satisfaction.

On approval, menu items are put into production—and then

only if the ingredients are available from qualified suppliers.

The production process, from receiving, to cold storage,

to grilling or baking or frying, and a dozen other steps, is

designed and maintained to yield a quality meal. Operations

managers, using the best people they can recruit and train,

also prepare effective employee schedules and design

efficient layouts.

Managers who successfully design and deliver goods

and services throughout the world understand operations.

In this text, we look not only at how Hard Rock’s manag-

ers create value but also how operations managers in other

services, as well as in manufacturing, do so. Operations

management is demanding, challenging, and exciting. It

affects our lives every day. Ultimately, operations managers

determine how well we live.

What Is Operations Management? Operations management (OM) is a discipline that applies to restaurants like Hard Rock Cafe as well as to factories like Ford and Whirlpool. The techniques of OM apply throughout the world to virtually all productive enterprises. It doesn’t matter if the application is in an office, a hospital, a restaurant, a department store, or a factory—the production of goods and ser- vices requires operations management. And the efficient production of goods and services requires effective applications of the concepts, tools, and techniques of OM that we introduce in this book.

As we progress through this text, we will discover how to manage operations in an economy in which both customers and suppliers are located throughout the world. An array of informa- tive examples, charts, text discussions, and pictures illustrates concepts and provides informa- tion. We will see how operations managers create the goods and services that enrich our lives.

In this chapter, we first define operations management , explaining its heritage and exploring the exciting role operations managers play in a huge variety of organizations. Then we discuss production and productivity in both goods- and service-producing firms. This is followed by a discussion of operations in the service sector and the challenge of managing an effective and efficient production system.

Production is the creation of goods and services. Operations management (OM) is the set of activi- ties that creates value in the form of goods and services by transforming inputs into outputs. Activities creating goods and services take place in all organizations. In manufacturing firms, the production activities that create goods are usually quite obvious. In them, we can see the creation of a tangible product such as a Sony TV or a Harley-Davidson motorcycle.

In an organization that does not create a tangible good or product, the production func- tion may be less obvious. We often call these activities services . The services may be “hidden” from the public and even from the customer. The product may take such forms as the transfer of funds from a savings account to a checking account, the transplant of a liver, the filling of an empty seat on an airplane, or the education of a student. Regardless of whether the end product is a good or service, the production activities that go on in the organization are often referred to as operations, or operations management .

Organizing to Produce Goods and Services To create goods and services, all organizations perform three functions (see Figure 1.1 ). These functions are the necessary ingredients not only for production but also for an organization’s survival. They are:

1. Marketing , which generates the demand, or at least takes the order for a product or ser- vice (nothing happens until there is a sale).

2. Production/operations , which creates, produces, and delivers the product. 3. Finance/accounting , which tracks how well the organization is doing, pays the bills, and

collects the money.

Universities, churches or synagogues, and businesses all perform these functions. Even a vol- unteer group such as the Boy Scouts of America is organized to perform these three basic

functions. Figure 1.1 shows how a bank, an airline, and a manufacturing firm organize them- selves to perform these functions. The blue-shaded areas show the operations functions in these firms.

The Supply Chain Through the three functions—marketing, operations, and finance—value for the customer is created. However, firms seldom create this value by themselves. Instead, they rely on a variety of suppliers who provide everything from raw materials to accounting services. These suppli- ers, when taken together, can be thought of as a supply chain. A supply chain (see Figure 1.2 ) is a global network of organizations and activities that supply a firm with goods and services.

As our society becomes more technologically oriented, we see increasing specialization. Specialized expert knowledge, instant communication, and cheaper transportation also foster specialization and worldwide supply chains. It just does not pay for a firm to try to do every- thing itself. The expertise that comes with specialization exists up and down the supply chain, adding value at each step. When members of the supply chain collaborate to achieve high levels of customer satisfaction, we have a tremendous force for efficiency and competitive advantage. Competition in the 21st century is not between companies; it is between supply chains.

Why Study OM? We study OM for four reasons:

1. OM is one of the three major functions of any organization, and it is integrally related to all the other business functions. All organizations market (sell), finance (account), and produce (operate), and it is important to know how the OM activity functions. Therefore, we study how people organize themselves for productive enterprise .

2. We study OM because we want to know how goods and services are produced . The produc- tion function is the segment of our society that creates the products and services we use.

3. We study OM to understand what operations managers do . Regardless of your job in an organization, you can perform better if you understand what operations managers do. In addition, understanding OM will help you explore the numerous and lucrative career opportunities in the field.

4. We study OM because it is such a costly part of an organization . A large percentage of the revenue of most firms is spent in the OM function. Indeed, OM provides a major oppor- tunity for an organization to improve its profitability and enhance its service to society. Example 1 considers how a firm might increase its profitability via the production function.

Figure 1.2 Soft Drink Supply Chain

A supply chain for a bottle of Coke requires a beet or sugar cane farmer, a syrup producer, a bottler, a distributor, and a retailer, each adding value to satisfy a customer. Only with collaborations between all members of the supply chain can efficiency and customer satisfaction be maximized. The supply chain, in general, starts with the provider of basic raw materials and continues all the way to the final customer at the retail store.

STUDENT TIP Good OM managers are scarce and, as a result,

career opportunities and pay are excellent.

Example 1 EXAMINING THE OPTIONS FOR INCREASING CONTRIBUTION Fisher Technologies is a small firm that must double its dollar contribution to fixed cost and profit in order to be profitable enough to purchase the next generation of production equipment. Management has determined that if the firm fails to increase contribution, its bank will not make the loan and the equipment cannot be purchased. If the firm cannot purchase the equipment, the limitations of the old equipment will force Fisher to go out of business and, in doing so, put its employees out of work and discontinue producing goods and services for its customers.

CHAPTER 1 | OPERATIONS AND PRODUCTIVITY 7

Example 1 underscores the importance of the effective operations activity of a firm. Devel- opment of increasingly effective operations is the approach taken by many companies as they face growing global competition.

What Operations Managers Do All good managers perform the basic functions of the management process. The management process consists of planning , organizing , staffing , leading , and controlling . Operations manag- ers apply this management process to the decisions they make in the OM function. The 10 strategic OM decisions are introduced in Table 1.2 . Successfully addressing each of these decisions requires planning, organizing, staffing, leading, and controlling.

Where Are the OM Jobs? How does one get started on a career in operations? The 10 strategic OM decisions identified in Table 1.2 are made by individuals who work in the dis- ciplines shown in the blue areas of Figure 1.1 . Business students who know their accounting,

APPROACH c Table 1.1 shows a simple profit-and-loss statement and three strategic options (mar- keting, finance/accounting, and operations) for the firm. The first option is a marketing option , where excellent marketing management may increase sales by 50%. By increasing sales by 50%, contribution will in turn increase 71%. But increasing sales 50% may be difficult; it may even be impossible.

CURRENT INCREASE SALES REVENUE 50%

REDUCE FINANCE COSTS 50%

REDUCE PRODUCTION COSTS 20%

Sales $100,000 $150,000 $100,000 $100,000

Costs of goods −80,000 −120,000 −80,000 −64,000

Gross margin 20,000 30,000 20,000 36,000

Finance costs −6,000 −6,000 −3,000 −6,000

Subtotal 14,000 24,000 17,000 30,000

Taxes at 25% −3,500 −6,000 −4,250 −7,500

Contribution d $ 10,500 $ 18,000 $ 12,750 $ 22,500

a Increasing sales 50% increases contribution by $7,500, or 71% (7,500/10,500).

b Reducing fi nance costs 50% increases contribution by $2,250, or 21% (2,250/10,500).

c Reducing production costs 20% increases contribution by $12,000, or 114% (12,000/10,500).

d Contribution to fi xed cost (excluding fi nance costs) and profi t.

The second option is a finance/accounting option , where finance costs are cut in half through good financial management. But even a reduction of 50% is still inadequate for generating the necessary increase in contribution. Contribution is increased by only 21%.

The third option is an OM option , where management reduces production costs by 20% and increases contribution by 114%.

SOLUTION c Given the conditions of our brief example, Fisher Technologies has increased contribu- tion from $10,500 to $22,500. It may now have a bank willing to lend it additional funds.

INSIGHT c The OM option not only yields the greatest improvement in contribution but also may be the only feasible option. Increasing sales by 50% and decreasing finance cost by 50% may both be virtu- ally impossible. Reducing operations cost by 20% may be difficult but feasible.

LEARNING EXERCISE c What is the impact of only a 15% decrease in costs in the OM option? [Answer: A $19,500 contribution; an 86% increase.]

statistics, finance, and OM have an opportunity to assume entry-level positions in all of these areas. As you read this text, identify disciplines that can assist you in making these decisions. Then take courses in those areas. The more background an OM student has in accounting, statistics, information systems, and mathematics, the more job opportunities will be available. About 40% of all jobs are in OM.

The following professional organizations provide various certifications that may enhance your education and be of help in your career:

◆ APICS, the Association for Operations Management ( www.apics.org ) ◆ American Society for Quality (ASQ) ( www.asq.org ) ◆ Institute for Supply Management (ISM) ( www.ism.ws ) ◆ Project Management Institute (PMI) ( www.pmi.org ) ◆ Council of Supply Chain Management Professionals ( www.cscmp.org )

Figure 1.3 shows some recent job opportunities.

The Heritage of Operations Management The field of OM is relatively young, but its history is rich and interesting. Our lives and the OM discipline have been enhanced by the innovations and contributions of numerous indi- viduals. We now introduce a few of these people, and we provide a summary of significant events in operations management in Figure 1.4 .

STUDENT TIP An operations manager must successfully address the 10

decisions around which this text is organized.

TABLE 1.2 Ten Strategic Operations Management Decisions

DECISION CHAPTER(S)

1. Design of goods and services: Defi nes much of what is required of operations in each of the other OM decisions. For instance, product design usually determines the lower limits of cost and the upper limits of quality, as well as major implications for sustainability and the human resources required.

5, Supplement 5

2. Managing quality: Determines the customer’s quality expectations and establishes policies and procedures to identify and achieve that quality.

6, Supplement 6

3. Process and capacity strategy: Determines how a good or service is produced (i.e., the process for production) and commits management to specifi c technology, quality, human resources, and capital investments that determine much of the fi rm’s basic cost structure.

7, Supplement 7

4. Location strategy: Requires judgments regarding nearness to customers, suppliers, and talent, while considering costs, infrastructure, logistics, and government.

8

5. Layout strategy: Requires integrating capacity needs, personnel levels, technology, and inventory requirements to determine the effi cient fl ow of materials, people, and information.

9

6. Human resources and job design: Determines how to recruit, motivate, and retain personnel with the required talent and skills. People are an integral and expensive part of the total system design.

10

7. Supply chain management: Decides how to integrate the supply chain into the fi rm’s strategy, including decisions that determine what is to be purchased, from whom, and under what conditions.

11, Supplement 11

8. Inventory management: Considers inventory ordering and holding decisions and how to optimize them as customer satisfaction, supplier capability, and production schedules are considered.

12, 14, 16

9. Scheduling: Determines and implements intermediate- and short-term schedules that effectively and effi ciently utilize both personnel and facilities while meeting customer demands.

13, 15

10. Maintenance: Requires decisions that consider facility capacity, production demands, and personnel necessary to maintain a reliable and stable process.
