This ninth edition has been revised to incorporate and integrate changes in the field of Operations Management, and the many suggestions for improvement received from instructors using the text worldwide. The following are key among the many revisions made:

• New text content on outsourcing, global operations, supply chain management and logistics, vendor managed inventory, technology and innovation. Much more coverage of services, including service quality and aggregate planning in services.
  
  
• Chapter 16, Supply Chain Management, has been revised and repositioned to Chapter 11 in order to reflect the growing importance of the concepts in this chapter.
  
  
• Throughout the text, new and updated readings, newsclips, and photos provide students with a real world, motivating view of the critical importance of operations management to businesses today. There are also five new cases and new and revised problems for assignment.
  
  
• The end of chapter resources include new Experiential Learning Exercises. These "exercises" encourage and challenge students to reflect on the chapter content and apply it to real life situations and problems.
  
  
• The student DVD-Rom, included free in all texts, has a new and enhanced user interface, a larger collection of new professional videos featuring major companies such as Ford, DHL, and BP, a new built in 'scene selection' function, an expanded set of Screencam tutorials, and enhanced Excel templates.
  
  
• Available for instructors, OM Video/DVD series Volumes 11 and 12, which include original professionally produced programs on Chase Bank, Ford, BMW, DHL, and BP.

• Clearly written explanations of concepts as well as methods. The Stevenson text has been the long time market leading title because it is understandable for undergraduate business students. This hallmark of the text results from the author's devotion to and experience in teaching combined with thorough development contributions and suggestions from hundreds of adopters.
  
  
• Up to date revisions incorporate the latest concepts and applications while not losing focus on the core concepts of Operations Management.
  While some titles may overemphasize the latest hot buzzword, Stevenson integrates new ideas carefully and appropriately so that students have a long lasting understanding of the important operations management considerations to carry forward in the rest of their studies and in their careers.
  
  
• The Stevenson text has always supported students in applying concepts and methods, with solved problems, examples, questions, problems, and cases. Students learn by doing, and the Stevenson text offers more support for 'doing Operations' than any other.
  
  
• Learning support for students-the text includes a Student DVD complete with updated Excel templates and screencam tutorials, data files, video scenes and longer videos from companies like DHL, BMW, BP, Ford, Honda, United Airlines, McDonalds, Louisville Slugger, Disney, and many more, self quizzes, web links, and much more. Students can also use web-based tools such as the Operations Management Center, the Interactive Operations Management modules, the many self study tools in the text Online Learning Center, and more.
