Just finished reading "Innovate Like Edison", written by Michael Gelb (author of How to Think Like Leonardo da Vinci) and Sarah Miller Caldicott (grandniece of Edison). I'm not usually a fan of the genre of books that tend to generalize one talented person's accomplishments into a system that anyone can follow.
But I must say, Gelb and Caldicott have done a remarkable job of synthesizing the key success factors of this great inventor and his organization into lessons that most anyone can use today. There are also some amazing parallels to what's happening today with 'open innovation' and Edison's own philosophies and approaches.
I've asked Sarah Caldicott to provide some perspectives on the book and she has agreed. So look for those posts within the next week or two. In the meantime, I've added this book to my 'recommended reading' list on innovation.
