Cagan and Vogel's book Creating Breakthrough Products is long overdue in the fields of business and (industrial)product design. It provides a realistic view of product development and a "behind the magic curtain" look at product successes and failures. The arguments, visuals, and product case studies provided in the book helped me envision a mental map that I can use in my work. It is a great read...one that every hardware and software product manager should read. The book is a solid contribution to the design field and would be great for industry and academia. Students learning this stuff will have a faster start toward more effective product design.
