And this book I thought was very good. He adopts a reflection of a large scale project for the Police in Sweden, and the aspects they learned by adopting lean practices as they went along. And then in later chapters more detailed reflections and background on subject matters. (I suspect the authoring style leads readers to think it was all accidentally knowledge gained by the team along the way, but knowing his previous experience I am sure he nudged most in the right direction).
His writing style and diagrams are very easy to follow and I finished the book in a few days read on the commute, and was very inspired. Highly recommended.
