Chapter-by-Chapter Changes▪ Chapter Count—Relative to the tenth edition, we have streamlined this edition by combining two chapters for a total of only 15 chapters, retaining four supplements in the book, and adding one new supplement in MyOMLab for a total of seven supplements. A central figure in the margin of each chapter shows how each chapter fits into our general theme of processes to supply chains.▪ Chapter 1, “Using Operations to Create Value,” defines operations management, supply chain management, and the overall framework for linking corporate strategy to key operations management decisions.
