This is the book those of us teaching product design in universities have been waiting for. I can't think of any area of product design and development that Otto and Wood haven't covered, and in real depth. I teach a course in product design at Ohio State, and this will be the book we'll use from now on. I especially appreciate the extensive references, and the emphasis placed on looking at real products to learn how to design better products. The chapter on product architecture is really a godsend - these are concepts that most engineering students don't run into in the standard curriculum, but they're crucial to sound product development. In short, an amazingly useful book, and one that will certainly be around for a long time to come.
