Plain-language definition

What Human approval gates means here.

A human approval gate is a defined point where a person with authority must approve, reject, escalate, or stop an AI-assisted action because the decision requires accountability, judgment, or tolerance for consequence.

Failure modes

What goes wrong when this control is poorly designed.

Reviewers see too little evidence to make a real judgment.

A reviewer cannot distinguish a safe result from a persuasive-looking result.

The gate is used for low-risk work.

Routine items clog the queue and encourage rubber-stamping.

Approvers have no authority to reject or change the action.

The organization creates accountability without control.

Every item looks the same.

Reviewers lose the signal that should tell them when judgment actually matters.

Measures of effectiveness

The control should make release behavior clearer.

  • Approval latency.
  • Rejection and escalation rate.
  • Post-approval incident rate.
  • Reviewer load and fatigue signals.
  • Decision rationale completeness.
