Most of the books about Lean use manufacturing related case studies and examples. As Lean is derived from Toyota's TPS, this is not surprising. So there is a real need for books that relate Lean principles and tools to the service environment, and this book definitely addresses that niche.
There is no doubting that the author knows his stuff, and he does try very hard to relate Lean to the service environment. A strong point about the book is that he wraps his approach within a framework, and gives ideas about what Lean tools can be used where. Like John Seddon - who he draws upon extensively - he cautions against simply applying Lean tools as this is over simplistic and can even be counter productive.
The book has some grave flaws, the principle of which is the presentation. It is amateurish and looks like it was knocked up in a word processor. The illustrations (mainly just simple line drawings) are poor - in some cases really bad (e.g. an arrow obscures text in the figure on p. 64, the examples on p. 126 are too small to be of any use and the process chart on p. 149 is simply awful). Similarly the tables are very poorly laid out: in an extreme case with words wrapping around at strange points and without hyphenation; personally I would have used a sans serif typeface in the tables which allows the font size to be smaller and still easily readable. The author also uses underlining in the text for emphasis - a throwback to the days of electronic typewriters and surely not needed where italic or bold can be used more effectively. Finally, and most significantly, the author makes several cross references to other parts of the book without giving page numbers or section headings. There is an index, but not all of the items he cross references are mentioned, so it can be quite difficult to find the section he refers to.
Also I do wish it was really more of a "toolbox": many of the tools are not described in enough detail to be able to apply out of this "box". He does give extensive further reading, but the use of the word toolbox is a misnomer.
The book is written in a clear, easy to follow style, and there is much to praise. The presentation lets it down though. I really want to like this book, and there is much of use within its pages, but the poor presentation and layout ultimately get in the way. If the author is considering a new edition (and I hope he is), I strongly recommend that he pays attention to detail and perhaps seeks a more professional publisher.
As there is no other book on Lean that addresses the service environment this book is to be recommended for that reason. But be prepared for the flaws.
