Query: Even as an ad it is not very good

This is nothing more than a rehashing of some very old concepts cleverly disguised(or so the author thinks) in a bunch of vague terminology. As a book it lacks substance. As an ad for the author's consulting service it doesn't offer enough too make anyone, with any knowledge or experience in this area, want to hire them. But if you are easily impressed by high-sounding terms and promises of speed to market and lots of savings, etc...then this book and many others like it, is for you. If you're looking for a real solution for designing better products, faster - look elsewhere.
