Domain-Driven Design: Tackling Complexity in the Heart of Software

If you’re trying to add automation to complicated human enterprise, then your software cannot dodge this complexity—all it can do is control it.

Play with the model as you talk about the system. Describe scenarios out loud using the elements and interactions of the model, combining concepts in ways allowed by the model. Find easier ways to say what you need to say, and then take those new ideas back down to the diagrams and code.

The greatest value of custom software comes from the total control of the CORE DOMAIN.
