It also involves ensuring that the domain model matches the robustness diagrams—in particular, that all entity objects that show up on robustness diagrams are represented in the domain model. In other words, we verify that we’ve identified the key abstractions from the problem space that we’ll need to implement the desired behavior.

We should also review to make sure these entity classes are populated with attributes and that ...
