They had a project in planning for 18 months but hadn't been able to start it. I was hired as a principal and given this one of my major impacts to deliver, though other things kept getting piled on in front of it. To actually get it done one weekend I sat down and cranked out a functioning POC that could easily and rapidly be extend into the fully working system.
Come Monday they were blown away to see the major progress of an actual working system, and loved the system and were very happy about it. Then the bike-shedding began, an order of magnitude more person hours was spent talking about it than it took me to build it and they required rewriting it because they a data library I used 'old tech and uncool'..
Hilariously that data library was actually a DDD system that created bounded contexts and enforced a domain model in them, but due to their lack of understanding they didn't see that! The hilarious irony!
I wasn't a DDD guy, though having been a high level architect for 15 years I was using all the things I have found that worked best. Some time later I was reading about DDD and realised that system was actually DDD. Of course by that time I had already left, to deliver working systems instead of waste time bike-shedding with cargo culters!
