Report the facts before the story
State the error, when it happened, who or what may be affected, and whether it is still active. Do not delay disclosure while trying to make the outcome look better.
Bring a recovery plan with your apology
List the immediate containment step, the proposed correction, and where you need authority or help. Separate verified facts from assumptions so the team can make sound decisions.
Prevent recurrence without overpromising
Identify the failed check, unclear ownership, missing review, or judgment error behind the mistake. Commit to a practical control and document the lesson where others can use it.
