Collect events when team members felt mad, sad, or glad and find the sources Source: Agile Retrospectives
Put up three posters labeled 'mad', 'sad', and 'glad' (or >:(, :(, :) alternatively). Team members write down one event per color coded card, when they've felt that way. When the time is up have everyone post their cards to the appropriate posters. Cluster the cards on each poster. Ask the group for cluster names. Debrief by asking:
What's standing out? What's unexpected?
What was difficult about this task? What was fun?
What patterns do you see? What do they mean for you as a team?
Asking and answering go around the team circle - an excellent way to reach consensus Source: Agile Retrospectives
Everyone sits in a circle. Begin by stating that you'll go round asking questions to find out what you want to do as a group. You start by asking your neighbor the first question, e.g. 'What is the most important thing we should start in the next iteration?' Your neighbor answers and asks her neighbor a related question. Stop when consensus emerges or the time is up. Go around at least once, so that everybody is heard!
A good debriefing deepens understanding, learning and sharing. Preparation: Download and assemble the Debriefing Cube and cards.
During the retrospective, roll the cube. Then draw a card from the category it shows and use it to prompt a discussion. Repeat as time permits.
This will broaden your debriefing options and is especially great for groups without a facilitator to enable them to effectively debrief on their own.
