Shadow Mode: how a new control earns the right to become mandatory

Start without authority

A new control should first demonstrate value beside the existing process. That lowers resistance and creates an honest comparison.

Use blind pre-signature inputs

The evaluation should only use information available before the commitment. Otherwise hindsight can make every warning look obvious.

Measure disagreement, not just agreement

The most valuable cases are where the new control and existing process differ. Those cases reveal whether the control catches material issues or simply adds noise.

Include false positives

A control that flags everything is not useful. Track cases where the existing process was better, where the new control was better and where they were equal.

Make mandatory status an earned outcome

If Shadow Mode shows repeatable decision value with acceptable friction, the organization can choose to move from advisory to required clearance.
