Control mapping should reduce complexity, not multiply policy artifacts.

Start with control objectives

Define what each control is expected to prevent or detect before mapping to frameworks.

Reuse where obligations overlap

Many framework requirements share evidence primitives. Reuse evidence collection pipelines.

Design ownership into evidence

A control without clear evidence ownership becomes brittle under audit pressure.

Keep AI-specific nuance explicit

Document model lifecycle, prompt controls, and non-human identity requirements directly.
