Four lists — Liked, Learned, Lacked, Longed for — give a balanced view of the sprint. Simple to explain and works for almost any team.

Everyone adds notes to all four columns, silently.
Cluster duplicates and read every cluster aloud.
Vote on clusters and discuss the top ones: what should change?
Agree 1–3 owned actions for next sprint.
