Situation

A small team has released a new permission model. Support issues appear, and members remember the original reasoning differently.

Retrospective structure

The release page links its Decision Brief, risks, and user evidence. Review begins with the original success conditions and known uncertainty.
Record which assumptions held, which signals contradicted expectations, and whether problems arose from execution or the original judgment. Each can become a task or review date.

Psychological safety

Focus on systems and information. A reasonable choice based on available evidence can still produce an unfavorable result.
The page retains outcomes and next actions so later members can understand continuing changes.
