For me as a lean practitioner, I found this book more of a refresher and a glossary of terms, rather than a book that can teach me how to implement Lean.
There is little on implementation, case studies, examples and only one formula for Takt time in the book, there is however an excellent example with guidelines on how to conduct a VSM (Value stream map), which is one of the most simplest examples I've seen to date.
Great for beginner's and there is a list of additional material (books/articles) for the reader to follow up on, which I always enjoy seeing and adding them to my reading list.
