While this book follows up Suh's 1990 monograph, Principles of Design, is substantially different in both content and approach. This is a textbook designed for graduate students and professional engineers. After covering the fundamental principles of axiomatic design in the first three chapters, it deals with design of systems, software, materials and materials processing, manufacturing systems, and product design. This volume contains case studies and research gathered over the last ten years since the publication of its predecessor.
