Direct answer

Human approval helps when a person has the authority, evidence, and time to make a meaningful judgment. It slows delivery when it becomes an indiscriminate review queue.

Teams add a person-in-the-loop because it sounds safe, then discover that no one knows what the person is approving or when they may reject the action.

Practical framework

Use this as the decision model.

  1. Separate review from approval.
  2. Use gates for consequence, irreversibility, uncertainty, and policy judgment.
  3. Show the reviewer the route class, evidence, and failure notes.
  4. Give the approver authority to reject, change, escalate, or stop.
  5. Track timeout, fatigue, and post-approval incident behavior.

Examples

How the issue shows up.

A low-risk internal summary may need sampling review, not approval.

Sampling can provide evidence without making every low-risk action wait.

A high-impact customer action may need approval with evidence and audit trail.

Approval is justified when the human can change the outcome and leave a record.

Decision criteria

Questions that make the next action clearer.

  • Would approval change the outcome if the AI is wrong?
  • Does the reviewer see enough evidence to make a decision?
  • Is the gate reserved for the decisions that actually need judgment?

Common errors

What to avoid.

  • Putting all AI output through the same queue.
  • Making reviewers accountable without authority.
  • Tracking approvals without tracking quality or incidents after approval.
