Distribute blank index cards and tell the team they have 10 minutes to write a postcard to a person the whole team knows (i.e. an ex-colleague). When the time is up, collect and shuffle the cards before re-distributing them. Team members take turns to read out loud the postcards they got.
Create a list of learning objectives for the team Source: Tim Ottinger
Hand out pens and paper. Each participant writes down what they wish their coworkers would learn (as a team - no need to name individual people). When everyone is done, collect all items on a board and count how often each one appears. Pick the top three things as learning objectives, unless the team's discussion leads somewhere else.
Brainstorm what behaviors to keep, drop & add and pick the top initiatives Source: Agile Retrospectives
Divide a flip chart into boxes headed with 'Keep', 'Drop' and 'Add'. 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.
Create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as 'Great' and the other as 'Bad'. Let participants stand on the scale according to their satisfaction with the retrospective. Psychologically, taking a stand physically is different from just saying something. It's more 'real'. See activity #43 on how to begin the retrospective with the same scale.
