Although much of this book is focused on products, much is relevant to any kind of group collaboration and creativity. This is a fascinating first-hand account for anyone who loves movies. Lumet's include Twelve Angry Men, The Pawnbroker, Serpico, Dog Day Afternoon, Network, The Verdict, and many others. It's interesting to us because movie making is a great example of a very complex collaborative project. Conversation is not just about conveying information or sharing emotions, not just a way of putting ideas into people's heads.
Conversation is a meeting of minds with different memories and habits.
That's the part that interests me. I bought this book initially because I loved the title. It resonated with a lot of interest in jazz as a metaphor for team work. Markets are conversations. They need to get a sense of humor.
