Human Oversight

Human oversight defines when people review, approve, override, stop, or appeal AI-assisted outcomes. It is only meaningful if the human has authority, time, evidence, and a clear decision boundary. Otherwise it becomes a rubber stamp attached to risk classification rather than a real control.

Oversight requirements

The EU AI Act’s high-risk system requirements include human oversight, and OWASP’s agent guidance also recommends human approval for high-impact actions. A practical oversight matrix looks like this:

Risk/actionAutomationHuman roleEvidence shown
Low-risk routingAutomaticRetrospective samplingInput, route, confidence, error label
Benefit denial recommendationHuman-in-the-loopMust approve before user impactPolicy text, source data, reason codes, model confidence
Tool action with external effectHuman approvalConfirm before send/delete/payRequested tool, arguments, recipient, policy decision
Incident or appealHuman review boardOverride and corrective actionAudit trail, similar cases, fairness metrics

The page for human-in-the-loop systems covers operational design; here the governance focus is whether the review changes outcomes and leaves evidence in auditability.

This control also supports compliance: it turns a legal or policy expectation into a concrete release gate.

Caveats

Humans are poor safety controls when they see too many alerts, lack context, or face productivity pressure. Measure override rate, time per review, error catch rate, appeal outcomes, and reviewer disagreement. If reviewers cannot detect the targeted failure, improve the model, interface, or policy enforcement rather than adding more nominal review.
