Conceptual integrity (Brooks 1975) is the state of affairs wherein a project or its ultimate product(s), and everybody involved, has a unified mental model of what it is and what it's for. Achieving conceptual integrity means decisions come easier and outcomes are more coherent, because there is little to no ambiguity around an optimal course of action.
