An approval step is useful only when the person reviewing has the information, time, and authority to make a decision.
Be specific about the decision
“Human in the loop” leaves several questions unanswered. What is the person approving? What happens before approval, and what can still be changed afterwards? Define the decision in the workflow: sending a response, updating a record, or taking another action. Name who is responsible and what should happen when they are unavailable.
Provide the basis for review
Show the proposed action, its supporting information, and the changes it would make. A reviewer should not need to reconstruct the system’s work from scratch. For a drafted response, make the relevant source material easy to inspect. For a record update, show the current and proposed values. Keep uncertainty visible without presenting a model’s confidence as a guarantee.
Allow a meaningful alternative
Give reviewers practical options to correct, reject, or escalate. A single approval button can turn oversight into a formality, particularly when the queue is long. Watch the time required and the kinds of changes people make. Frequent corrections may point to a design problem that should be fixed upstream.
Learn from the review
Record decisions with enough context to investigate mistakes and improve the system. Agree on how long those records are needed and who may access them. Revisit the review process as the workflow changes; adding more approvals does not automatically make a system easier to govern.
