I thoroughly enjoyed this book!
Having an interest in software companies and seeing how they evolve is fascinating to me, and seeing how a "non - Software" executive dealt with the sinking ship with a business strategy was very interesting to me since we are always told how great Gates and Jobs are...
My company is going through a major transformation and I found this a really interesting insight to similar major changes at IBM and how one leader dealt with this. It covers the highs and lows/challenges and successes. IBM is clearly a massive complex entity and I was fascinated how such complexity still in the end has to be able to be summarised and netted out to understandable language and concepts. One gets the impression from the book that Gerstner brought this executive ability to take a helicopter view of things. He also was prepared to take tough decisions.
