Remember, this was published in 1990, and today is out of date. If you have come looking for specific examples, or secrets of how the Japanese have been making such huge gains, THIS IS NOT FOR YOU. The book is great from a historical standpoint, but it misses totally on any detailed examples of what Toyota has done. Anyone in manufacturing who has not heard of work-circles or suggestion boxes, would probably find this a great read with lots of info, but for the rest of us, this is just a history book. Go for Lean Thinking instead.
