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

by Evans Eric

A model is a selectively simplified and consciously structured form of knowledge. An appropriate model makes sense of information and focuses it on a problem.

It is more like moviemaking, loosely representing reality to a particular purpose.

1. Binding the model and the implementation. That crude prototype forged the essential link early, and it was maintained through all subsequent iterations.

Cultivating a language based on the model. At first, the engineers had to explain elementary PCB issues to me,

Distilling the model. Important concepts were added to the model as it became more complete, but equally important, concepts were dropped when they didn’t prove useful or central.

is the creativity of brainstorming and massive experimentation, leveraged through a model-based language and disciplined by the feedback loop through implementation, that makes it possible to find a knowledge-rich model and distill it. This kind of knowledge crunching turns the knowledge of the team into valuable models.

This distillation is a rigorous expression of the particular knowledge that has been found most relevant.
