Make the proposed action reviewable
Before asking someone to approve a message, show the recipient, the channel and the exact words. Before asking to publish a page, show the page. Before changing a system, explain the resulting behavior and how to reverse it.
The person reviewing the action should be deciding about the result, without needing to reconstruct it from a stream of technical notes.
Keep the scope attached
Approval of one draft is approval of that draft. A changed audience, a new claim or a different attachment may change the decision. Keep the approval attached to the version that was actually reviewed.
The same principle applies to access. Permission to read information does not automatically authorize sending it elsewhere. A useful system keeps these permissions separate and visible.
Close the loop with evidence
After an action, record what happened and where. Distinguish a prepared draft from a delivered message, and a test from a real deployment. If something failed, say what failed and what is still pending.
Good approval flows are quiet when work is routine. They bring a person a specific decision at the moment their judgment changes the outcome.
