I listened to the audio book and it is a good example of finding a blue ocean without any patent protection in a crowded, competitive space.
The book is good from a business perspective though it now well written or put together.
It was a tad too long for my liking and I believe could have been condensed. I did not like that it jumped chronologically from 1982 to 2005 and back to 1991 and then to 2011 and then to 1995 which made it hard to follow. At times stories were told that did not seem to flow well either.
The names were hard to follow and keep track of and I wish I had written them down.
Also, I wish the book had explained in more detail how it broke into the STEM and LEGO competition markets which it did not explain.
A good book really only for the Blue Ocean Strategy piece.
I would have a hard time recommending this due to my comments above.
