Query: So many words - so little to say!

Although this is a painfully repetitive book, the author does have a few interesting things to say. However, most of it is common sense, and if you've been modeling for any length of time you are likely to be familiar with this stuff.The worst point about this book is that it doesn't discuss Model Driven Architecture (MDA). This is the latest initiative from OMG, and the future of UML. In fact, agile modeling practice seems to run counter to MDA in several important areas. In light of MDA, agile modeling seems to be quite a bad idea!I think Scott Ambler doesn't do himself (or his readers) any favours by stretching out what is really a very lightweight topic to fill such a large book.
