Begin with a limited set of node types such as objective, product line, program, team, role, workflow, decision, system, source, and outcome signal. Define edge meanings explicitly: owns, contributes to, depends on, approves, executes, informs, or measures. Each type should state its canonical source and responsible steward. This discipline prevents visual similarity from turning unlike concepts into interchangeable circles.
Time and version matter. Ownership can change, a workflow can be superseded, and an objective can end. The graph should distinguish current, historical, proposed, and inferred relationships. A generated suggestion that two workflows should connect is not the same as an approved operating dependency. Proposed edges can support planning, but they need labels and review before entering the current operating map.
