Good coders learn enough about the business to check the code. Domain experts can look at the running software.

With DDD you just get a third model that is neither the domain, nor the software, and both the domain experts and the programmers will have to work extra to maintain and understand it.

Worse, people often try to build this model up front, which means it will be wrong, hard to implement and probably get thrown away if you actually want to ship anything

I think people are getting triggered by the word domain, and conflating it with a particular cargo cult called DDD. It's the same with agile - the one that's implemented is usually the cargo cult version that charges you the cost of the "official" process without the benefits.

I meant domain modelling in the simplest sense: I created three objects, the market, the trading strategy and a simulated version of the market. that's it. no paperwork, no forms filled in triplicate.
