Summary
Eric discusses the need for strategic thinking an how early design decisions have major impact on the organization and the entire development process. He uses the lens of DDD Strategic Design principles (emphasizing "Context Mapping" and "Distilling the Core Domain") to show how to avoid strategic failures and achieve strategic successes. Winning strategy starts with the domain.

Eric Evans obviously is a very good speaker.
-
Eric's ways seems much like the SOA concept, wrap the legacy system and map the different model; reuse the services to make the new features.
-
I almost quit the industry until 2/3 of the way through when he admitted he was probably depressing responsible architects and designers :-)
Yes, it does sound like the SOA technique of wrapping Legacy systems, that's hardly a new concept, but with 22 years experience, I don't find any of Eric Evans ideas are new, but I do find it nice that he's bundled them together and is evangelizing the importance of good engineering and design practices and domain modelling in particular. -
Fully agree with the content and the proposed method. The problem is, that many large companies have huge legacy "system-landscapes" (=big balls of mud) that have successfully survived previous attempts to migrate, clean-up etc. and meanwhile their maintenance is so expensive that phasing them out is a must from purely a financial point of view.
What I notice is that usually these companies start every 3-5 years such initiatives as described at the beginning of the presentation and end up in the same situation (year 2 usually means the end of it). Due to the fact that after such failures usually the management is also exchanged, it is almost impossible to have any discussion about a different approach... -
Spot on. It takes more than 2 years to replace these large IT systems but that's as long as management is willing to wait, so they always fail.
The trick is to cut the thing into pieces and have staged deliverables. Sometimes that's not easy, when like you said, all you have is a big ball of mud (or as I like to describe it, a sagging carboard shanty that the users want you to wallpaper, add gold faucets, and hang a chandelier in.) -
I normally listen to the presenations when commuting.
Why there's no audio to this presentation posted?
