Query: Definitely not worth the money

If you are working for a company that makes software, chances are you have a guy who is assigned the task of release management. Do yourself a favor and go talk to this guy -- you'll probably get better insights than this book has to offer after draining $50 bucks out of your pocket. I only gave it 2 stars since the author touches on the right topics but fails to deliver useful content.He delves into one specific style of release management and engineering (probably what the author's company does) and does not talk too much about alternate styles at all -- and the release methodology suggested by the book is less elegant than some of the release processes I've seen.And as a bonus, a few blank pages serves as the index for the book. I was expecting better quality of content and presentation from Prentice Hall.
