The book covers in detail what is agile modeling and how to implement it. The author delves into the often uncharted territory of agile requirements engineering and agile software design. In these two particular topics I found the book to be pretty useful and I learned some new fresh perspectives on how to solve these problems. The book, though, is unnecessary long and the author tends to be too verbose, often reiterating over and over the same ideas to the point of absolute boredom. I found it really difficult to read the book cover to cover and skipped several pages, just browsing, looking for interesting headlines where to stop and read further. The book is old and some of the methodologies mentioned in the book may be considered outdated by many (e.g. the book has a chapter on how to do agile modeling with RUP). Many reference links to other materials mentioned in the book are no longer valid and the referenced web pages do not exist.
For us techies, this was an easy read while still informative. This is a book that I keep on my shelf for reference from time to time to make sure that I am approaching projects correctly. Adding Agile methods to my project management approach has helped me to keep moving forward, while pleasing the customer as well. Any developer (programming or not) who has not read this, should take the time to read it and learn from the approach.
My wish would be that more disciplines would adopt these principles.
One of the first books about agility that I've read. A lot of my thinking comes from this one book. It gives you a solid mind set about agility from the modeling perspective. But it's not limited to modeling. It's about being an effective developer.
