Recently, my development team has started up our Friday Lunch-n-Lean sessions where we all read a chapter of a given book and discuss that chapter amongst the group during lunch on Fridays. We're now on Chapter 2 of Domain Driven Design, by Eric Evans.

When I first started reading DDD around a year and a half ago, I honestly thought the first 4 or 5 chapters were wordy, boring and repetitious. Going back to the beginning of the book with my experience and knowledge from the last year and a half, I can't believe that I thought this.

The first two chapters alone have been completely mind-blowing for me, on my second read of the book. I don't know if it's the combination of other knowledge, the experience I've had trying to implement DDD's concepts, or what... At this point, I can hardly turn a page without having 10 or 15 highlighted phrases and sentences. Seriously - there's rarely a page in the first two chapters that does not have something highlighted.

If your involved in any part of software development - management, analysis, development, documentation, or anything else - and you've never read this book; you need to read at least the first 3 chapters at least 3 times, if not the entire book.
