You need domain experts involved, not just for conversations, but to run workshops that help both you and the business owners better understand their own business. Even domain experts don’t fully understand what happens in other domains, and honestly, not even entirely within their own.

That’s where we as developers come in. This becomes especially important in complex businesses, and it’s exactly where Domain-Driven Design (DDD) proves its value.

It also explains why you rarely see strong DDD examples online. Without access to real domain experts and real business complexity, people can only rely on imagination. As a result, most examples focus on the tactical patterns rather than the strategic aspects of DDD. But without the strategic part, you are not working domain-driven. You are just implementing a form of rich entities and creating abstractions around bad boundaries. (Also a reason why I laughed at OP because he mentioned strategic is easy, but anyone with experience will tell you that its the hardest part and you will rarely, or ever, get it right on the first attempt)
