Ideology of Lean Startup is really valuable. I believe there's some truth behind what Eric Ries is talking about. The main idea of Lean Startup is that is valuable to measure the ideas in the market and be willing to learn from the results and pivot the course if needed.
I especially liked what Eric wrote about what actually is an MVP. In my own believes I often seen MVP to be much less than companies are themselves thinking it to be. Also validated learning, innovation accounting and the whole build-measure-learn loop were valuable parts of the book.
What I didn't like was that the book wasn't anywhere close to minimum viable book. It was utterly too long and once in a while even boring. I believe the ideas of the subject could have been delivered in 100 pages. That would have proven the value of the thinking. Now it was as any other ordinary book, lengthened to almost 300 pages in order to seem as a "normal" book. I just hate that approach. When there isn't that much to say, why to waste so many pages on it.
I feel bit bad to criticize the book since, I think that everyone should learn about the Lean Startup methodology. It is valuable and would help many companies and startups to succeed. I believe the book just isn't the best way to learn about the subject.
