I was lucky enough to see an early version of this book (while it was going through a technical review phase), and I really liked it. I found a lot of information in here that I'm trying to pull back into meetings and other activities here at work. (It's a long, slow road.)
The authors have a good writing voice, and an important message. It makes for a compelling book. One of the things I enjoyed was the continuing use of example stories, it really showed how the methods would be used in situ.
If your team needs some help changing the way you do business (or maybe the way you don't do business), this is the book for you. Go grab a copy while they're hot.
