by Ken Schwaber
I bought this book when it looked like I was going to be doing the Certified Scrum Master course at the ACCU Conference, as it's required reading. I was hoping for a detailed explanation of the Scrum process, but this book actually contains a number of case studies which describe how Scrum has been implemented in different places, what worked well and what didn't.
Even thought the book didn't contain what I expected, I found it quite interesting and informative and it made me think about how our agile team could improve. It's quite a short book at only 153 pages and very easy to read. Consequently I ploughed through it in about a weeks intensive reading.
