Mike Cohn not only has a wealth of experience but also the ability to tell his story in an understandable and compelling way. The result is that the reader walks away saying, "OK! I get it. I don't know why I thought this would be so hard!" These stories are more than the details of the mechanisms of writing user stories. Sure, that's good all by itself. The big, important thing about this book is that the details are cast in an expansive foundation that really shows you how effective teams work with each other and with customers. That's why I give this two thumbs up!
