Kick off your retro with instinctive thoughts about the last sprint.
- What did people love?
- What did people hate?
- What did people learn?
Everyone in your team should be able to think of at least one thing for each category. Ask them to write them on posts its, then when they are ready (in about 5-10 min) ask them to stick their post its on the wall and explain their answers.
This activity naturally leads into the Starfish, where people can turn these thoughts into actions for how to act during the next sprint.
