I found an entire paragraph that had been copy-pasted from one chapter to another. Poor writing and editing lowered my opinion of this book, as well as not having a strong summarizing chapter. I didn't realize it was ending until I saw the Appendices starting.

What a good book for those who are interested in strategy. Very clear examples with many case studies on how some companies get a big profit by leaving the traditional red oceans of competitions for blue oceans where they are unique.
it's a little bit unfortunately for me that I've recently read this book while it was actually published more than 12 years ago. In the past 12 years, the strategy of companies has changed a lot, come along with changes in the market, mostly because of the technology revolutions. So some ideas in this book become common sense nowadays.
Even though I don't find some big "new" things in this book, but many pieces of advice, as well as approaches to blue oceans how to create our own market, are still very useful.

This well-written book seems like common sense however it is an eye-opener for less sophisticated colleagues who doesn't know much about competitive advantage. It arguments how contested markets ("red oceans") should look for uncontested markets ("blue oceans"). Everything in this book is common sense. Nintendo is another high-profile example. Satoru Iwata, Nintendo's CEO, has referred to the Blue Ocean Strategy in interviews.

I do think the Blue Ocean Strategy is nothing without execution though. I think a large number (maybe more than 50%) of companies do not have a strategy. So it is not just execution that is missing. In fact, execution is easier once you have a strategy. This book, like many other business books, fails because it only talks about success stories. It does not talk about the majority of examples of Blue Ocean failed or currently marginal businesses:
- SPARSH, an innovative computer interface (google Pranav Mistry)
- Electric cars, which were invented in 1899!

I wouldn't highly recommend it but its an interesting read for someone new to this concept. For others, I would suggest or should look at "The Innovator's Dilemma" by Clayton M. Christensen for a better treatment of the ideas and the root causes for why they work.
