Each participant tells a story about the last iteration that contains certain words Source:
Provide everyone with something to write down their story. Then introduce the shaping words, which influence the story to be written:
If the last iteration could have been better: You set a couple of shaping words, e.g. such as 'mad, sad, glad' or 'keep, drop, add'. Additionally they have to write their story in first person. This avoids blaming others.
If the last iteration was successful: The team can either choose their own set of words or you can provide random words to unleash the team's creativity.
Now each participant writes a story of no more than 100 words about last iteration. They have to use each shaping word at least once. Timebox this to 5-10 minutes. When everyone's finished, they read out their stories. Afterwards lead a discussion about common themes of the stories.
Each team member explores one topic in depth in a series of 1:1 talks Source:
Each participant writes down one topic they want to explore, i.e. something they'd like to change. Then form pairs and spread across the room. Each pair discusses both topics and ponders possible actions - 5 minutes per participant (topic) - one after the other. After 10 minutes the pairs break up to form new pairs. Continue until everyone has talked to everyone else. If the group has an odd number of members, the facilitator is part of a pair but the partner gets all 10 minutes for their topic.
Divide a flip chart into boxes headed with 'Start', 'Continue' and 'Stop'. Ask your participants to write concrete proposals for each category - 1 idea per index card. Let them write in silence for a few minutes. Let everyone read out their notes and post them to the appropriate category. Lead a short discussion on what the top 20% beneficial ideas are. Vote on it by distributing dots or X's with a marker, e.g. 1, 2, and 3 dots for each person to distribute. The top 2 or 3 become your action items.
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.
