A series of 16 case studies that demonstrate how industry makes use of the best practices found in the text The Mechanical Design Process, 6th edition and the book Scrum for Hardware Design. Case studies have long been used in business schools but only rarely in engineering studies. However, studying how professionals have solved design problems is one window on the design process that is useful to students and practitioners.  What is unique about these case studies is they are not overly academic as they are co-written by practicing engineers to show real world examples of good practice.  The case studies range from those featuring very small companies to NASA and BMW. They range from the design of bicycles to heat exchangers. They include systems that are solely of hardware to those with integrated electronics and software.
