The Toyota Product Development System, James M. Morgan and Jeffrey K. Liker, Productivity Press, 2006.
Toyota’s lean manufacturing system has had a lot of press, but lean influences their product development approach as well. This book emphasizes the system aspects of their approach. Along the way it explores a variety of practices and tools: set-based approaches, use of a chief engineer, alignment, and more. I preferred this book over Kennedy as it feels both broader and deeper.
