The whole team wears one thinking mode at a time: facts, feelings, risks, benefits, ideas, and process. Prevents debate ping-pong and gives quiet voices structure.
Explain the hats and agree the focus question for the retro.
Only data and events from the sprint — no interpretation yet.
Gut reactions to the sprint — no justification required.
What could go wrong, what's fragile, what worries us.
What went well and why; what strengths can we build on.
Generate improvements freely — build on others, defer judgment.
Pick the strongest ideas and turn them into owned actions.
