DBing...is trying something...monitoring results, and adjusting accordingly to meet your goals. If you achieved your goal (provided it is small enough), bingo!
Ummm.. I think this is a tad bit of an oversimplification don't you?
The text is over 200+ pages... I hardly think this is even a halfway fair summary of the db process...
I agree with Frank. DB & DR lay out fairly specific approaches to dealing with hurting marriages in a way that gives a very large chance of reconciliation (as opposed to D). One of the strong points of DB is that it is not rigid, but is flexible in taking into account how one's spouse may react, and adjusting accordingly. However, it seems to me that one can faithfully apply all of the DB techniques and still not be able to save the marriage. That does not in any way invalidate DB principles.
There are other approaches (such as Retrouvaille) that take a somewhat different tack - the primary difference is that RV is couples work, whereas DB appears to be primarily oriented towards one spouse in the marriage. Hence, I view the two as complementary.
