"Well distilled and nicely told"
(Redwood City, California)
One of the more drastic transitions at my current job was formally adapting Scrum in place of an informal, best-effort approach we used before. This book helped me grasp what Scrum is really about in less than an hour. There is no filler here, no anecdotes nor reiteration. Pure content, well distilled. Just what I needed. We have been trained more thoroughly since but it was this book which got me going.
I wish more introductory books were like this one: skipping the waffle, delivering just the gist of the subject.
Update: when I originally wrote the review, the book had display problems on Kindle Touch. This issue has been fixed since. The font size is very small but legible. One could argue this is deliberate for an introductory reference material, this way it's very easy to leaf through the book.
