I quote: "He left my office impassive, and leaves me banned I had to be a bit too assertive ...." I do not expect much literary technique. This book is really not what I expected. It aims to develop the steps of lean but drowning the reader in a bogus story uninteresting ... In addition, continuous improvement is not really brought the examples are very specific to the SI and do not adapt to the production. I do not recommend this book, of course. I will try to the refourguer at work, little hope.
