I started reading this book yesterday and finished this afternoon. This morning I had a long meeting, yet it is so fluent and enjoyable reading that it just flew. I was on the final page in no time. This is a book on differentiation and it is indeed a very good one. It is not like the recent ones which I criticised in my other book reviews. It is honest and more importantly it provides us with so many European-based examples. This is a very welcome addition to the strategy literature as nearly all quoted game changing-strategy cases/examples come from the US. Seasoned readers I believe are tired of reading the same old iPod, IKEA, amazon.com, google etc. cases There are so many wonderful and eye-opening (and entertaining) examples here, like 'confession on the road' or 'support a nun' ideas.
The book does not claim to have a theory of differentiation. This is -to a large extent- true. But it does not reduce the usefulness of the book at all. Instead of providing a holistic theory of differentiation (could there be one?) the authors instead structure the book around 17 rules for challenging conventional business thinking and then move on to explain each one of these rules with wonderful examples. The prose of the book is so nice that it feels like you are reading fiction. Yet it sparks a lot of creative ideas in your brain. I believe this is a must read for those who are in search of a pragmatic guide for differentiating their business.
I am also very surprised that I am the first reader to write a review about this wonderful book even thouh it has been on the market since 2007. I suggest that the authors should borrow a few ideas from some of their American colleagues and ask at least 10 friends to write 5-star reviews about their book so as to get noticed. I am happy that mine is the first five-star review as this beautiful book more than deserves it. Thank you Anja and thank you Peter. Keep writing.
