Human-in-the-Loop

The important difference from “review after execution” is that in this pattern, approval is taken **before** the action. An action that has already been done and is later found to be wrong may not be reversible.

Designing those points well is the difference between a system that reduces work and a system that only changes the kind of work. If everything needs approval, the manager becomes a full-time approver. Approval points should be set by risk, not uniformly.
