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 histogram on how well ritual meetings went during the iteration Source:
Prepare a flip chart for each meeting that recurs every iteration, (e.g. the Scrum ceremonies) with a horizontal scale from 1 ('Did not meet expectations') to 5 ('Exceeds Expectations'). Each team member adds a sticky note based on their rating for each of these meetings. Let the team discuss why some meetings do not have a rating of 5. You can discuss improvements as part of this activity or in a later activity such as Perfection Game (#20) or Plus \& Delta (#40).
What would make the next iteration a perfect 10 out of 10? Source:
Prepare a flip chart with 2 columns, a slim one for 'Rating' and a wide one for 'Actions'. Everyone rates the last iteration on a scale from 1 to 10. Then they have to suggest what action(s) would make the next iteration a perfect 10.
Hand out sticky notes and markers. Write the big problem you want to solve onto a note and stick it to the top of a wall or big board. Ask the participants to write down ideas of what they can do to solve the problem. Post them one level below the original problem. Repeat this for each note on the new level. For every idea ask whether it can be done in a single iteration and if everyone understands what they need to do. If the answer is no, break it down and create another level in the problem solving tree.
Once you have lower levels that are well understood and easy to implement in a single iteration, dot vote to decide which to tackle in the next iteration.
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. Ask people what they notice.
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.
