New structure, but core content remains
4 stars
I read the 1st edition back in 2008 and then it was about the only book about agile covering both the process and the technical side.
The 2nd edition still has both, but also a new concept of "zones" of agile ability that make it clearer what can be done to focus of each ability.
I would recommend this book to anyone who wants a well structured take on what is needed to become agile. I have seen far to many projects that were agile in name only and agree with Shore's approach of "follow my book to the letter, see it work after some time and then adjust"
