There are many books on the Toyota Production System, however none explain the true essence of Toyota's success as Mr. Liker's book. The fourteen principles that are the basis of Toyota's continued success are explained in a clear and convincing manner based on the author's 20 years of studying Toyota. Get this book if you truely want to understand why Toyota is the best manufacturing company in the world.
From the prospective of an engineer in the defense industry, it is fascinating to learn how one company can employ many people so efficiently. The focus on real product value, from the customer's view, and long term vision is impressive. It does not fully answer all the questions it raises, but is a very good introduction to a different company philosophy. I would not recommend this as an entertaining book for everyone, but for those with an interest in business and engineering, it is very informative.
The Toyota Production System can be beneficial but this book is more about tooting toyota's reputation as the best company. You can get all the guidelines on TPS from any free website without having to read about the history of the Toyota company.
