This five-phase methodology begins by defining decision-relevant environments and classifying them by operational constraints, then establishes common security outcomes, baseline requirements, and fixed control intent. It guides teams through a repeatable process to manage controls based on feasibility and local conditions.

The storyboard also explains how to distinguish approved alternatives from true exceptions, govern residual risk, assign decision rights, report enterprise-wide exposure, validate the model in selected environments, and reuse it when business or technology conditions change.
