The engine & the lenses
Several dimensions, coupled at runtime.
Coupled at runtime — not analyses side by side
Two portable patterns — the trap and the AND-gate
A reasoning instrument for public policy based on complexity — it couples several analytical lenses at runtime to show not just what a policy does, but why.
A public policy is one of the ways a state intervenes in its environment to pursue goals, express priorities, and steer change. So CPAF reads a policy's outcomes against that intent, not only against whether a problem shrank — exactly the value a single efficiency lens cannot see.
