The book makes one mistake on its own cover. The apparently "bad" angel is sitting on the person's right shoulder, while the "good" angel, on his left. If this book wants to be a hundred percent correct, I suggest for the locations of the two angels to be swapped. Everyone in the world knows that the right hand is the "good" hand. There is no reason for the bad angel to sit on the person's right shoulder, unless of course the angels represent two different brain hemispheres and are controlling the opposite sides of the body.

Please change the cover. Thank you.

Excellent introduction to Agile development - said as a person who is just getting into understanding Agile development. I have worked with Waterfall, RUP and Lean development methodologies and really like the mind set surrounding Agile.

This book covered a lot of ground though didn't go too deeply into any one topic, which made it easier for those learning agile to understand it through this 1000 foot view of the methodology.

I really like this book as an introduction to agile methodologies and a discussion of good software development principals. The text was very accessible and made for an easy quick read. The author used devils and angels on our shoulder to explain good software practices and shun us away from the bad. Much as in real life we often have a devil and angel talking to use when making tough decisions. The book even explains what it should feel like when you are following an agile methodology and warns of potential obstacles. Overall I would recommend this book to anyone who wants to further develop their knowledge of software engineering principals or just become a better software developer.

This book is a great introduction to the Agile Development process. This is one of those books that should be read by any developer.

You may think you already know about fast development, but you are not if you haven't read this book. It's written for faster reading, you don't need more that two hours reading on one week to finish it. Greats tips for you daily development.

Read it and improve your development skill.
