Operations managers need a resource that will enhance their experiences with relevant examples and discussions. This fourth edition arms them with the information they'll need to succeed. The material has been completely reorganized with a focus on the current thrusts of operations management: strategy, six sigma, lean, and supply chain management. Several case studies have been added to show how the concepts are applied on the job. The pages are now in two colors to enhance the images and exhibits integrated throughout the chapters. In addition, the heavier quantitative material is minimized to provide operations managers with just the coverage needed and examples that illustrate a particular concept.
