My thoughts
Lots of great scenarios/templates for their four parts of a retrospective:
set the stage: Time to “arrive”, get into the right mood and focus on the goal.
Gather Data: Help everyone remember and create a shared pool of information.
Generate Insights: Why did things happen this way? Any patterns? See the big picture.
Close the retro: How could the retrospectives improve? Also clarify follow-up.
An amazing resource.
