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).
Find the source of problems whose origins are hard to pinpoint and lead to endless discussion Source:
Write the problem you want to explore on a sticky note and put it in the middle of a whiteboard. Find out why that is a problem by repeatedly asking 'So what?'. Find out the root causes by repeatedly asking 'Why (does this happen)?' Document your findings by writing more stickies and showing causal relations with arrows. Each sticky can have more than one reason and more than one consequence Vicious circles are usually good starting points for actions. If you can break their bad influence, you can gain a lot.
Prepare a flip chart with a playing schedule for quarter-final, semi-final and final. All participants write down actions on a post-it until you have eight actions. Shuffle them and randomly place them on the playing schedule. The team now has to vote for one of the two actions in each pair. Move the winning action to the next round until you have a winner of the impediments cup.
If you want to take on more than one or two actions you can play the match for third place.
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.
