Am I the only one who sees a direct connection between little bets and the lean startup movement? When you test your assumptions you are making a series of small bets. When you build a minimum viable product that is in effect making a small bet.
The book itself doesn't break new ground, so much as it synthesizes a lot of lean startup principles and gives some good anecdotes, some of which I hadn't read before (e.g. Gehry's architecture approach). It's a good read, I enjoyed it. Until Eric Ries' book comes out, it's actually the book I'd give people to teach them what a lean startup is.
