Applying Domain-Driven Design is not easy. It requires time and effort to get around the Business Domain, terminology, research, and collaboration with Domain Experts rather than coding jargon. You'll need to have the commitment of Domain Experts for getting involved in the process too. This will requires an open and healthy continuous conversation to model their spoken language into software. On top of that, we'll have to make an effort to avoid thinking technically, to think seriously about the behavior of objects and the Ubiquitous Language first.
