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.
Collect what team members perceived as good, bad and non-optimal Source:
Put up three sections labeled ‘The Good’, ‘The Bad’ and ‘The Ugly’. Give everyone 5 minutes to note down one or more things per category from the last sprint. One aspect per post-it. When the time is up, have everyone stick their post-its to the appropriate labels. Cluster as you collect, if possible.
Split a large group into smaller ones that create posters Source:

After you've identified an important topic in the previous phase you can now go into detail. Have the larger group split up into groups of 2-4 people that will each prepare a poster (flip chart) to present to the other groups. If you have identified more than one main topic, let the team members select on which they want to work further. Give the teams guidelines about what the posters should cover / answer, such as:
What exactly happens? Why is that a problem?
Why / when / how does this situation happen?
Who benefits from the current situation? What is the benefit?
Possible solutions (with Pros and Cons)
Who could help change the situation?
... whatever is appropriate in your setting ...
The groups have 15-20 minutes to discuss and create their posters. Afterwards gather and each group gets 2 minutes to present their results.
Condense many possible actions down to just two the team will try Source:
Lydia Grawunder & Sebastian Nachtigall
Hand out index cards and markers. Tell everyone to write down the two actions they want to try next iteration - as concretely as possible (SMART). Then everyone pairs up with their neighbor and both together must merge their actions into a single list with two actions. The pairs form groups of 4. Then 8. Now collect every group's two action items and have a vote on the final two.
Let team members appreciate each other and end positively Source:

Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
