I guess I've read too many similar books these days, but it feels this book does more to reinforce some ideas, than to add much to what I've already seen. The premise is good, and there's plenty to mull over. On the other hand, not sure how much to learn from specific examples of companies having done such innovation that the author suggests. I would be there's a big part of survivorship bias in it, just learning from the companies that made it through the tough times, and seeing what did they do different compared to their former selves, instead of what did they do compared to others who did not survive. It's also interesting to see how the business cases of some of the same companies are shown in different light in this book than in others, definitely every author picks and chooses the parts that fits them more. All in all added, but not much, to my toolkit.
