This book is designed to help product developers learn how to improve their processes around product development. The author walks the reader through 12 companies that are in various stages of the Lean Product Develop transformation. Unfortunately, the author kept these examples very high level and didn't go into as much detail as I would have liked. This book provided high level examples that make the case that Lean is a useful way to do product development, but didn't go into enough details to really make this a handbook for implementing the changes.
Furthermore, there were little to know examples of the product A3s that were referenced and only a few examples of the changes in scheduling. The author provides great insight that these tools work by showing that many of them are essentially must haves to be successful. However, something just felt missing in terms of HOW to do something of these things.
Finally, the editing of this book was sloppy which made it less appealing to read. There were awkward placement of pictures and inserts that made following the book jarring.
I believe that combining this book with other books on Lean Product Development is key. If this was my first introduction to LPD this would have been extremely powerful, however I've already read several books on the topic.
tl;dr: Great introduction to the concepts of Lean product development, less useful if you're looking for a more detailed guide.
