Place a circle or sphere in the middle of a free space. Let the team gather around it. Explain that the circle is the center of approval: If they agree to a statement they should move towards it, if they don't, they should move as far outwards as their degree of disagreement. Now read out statements, e.g.
I feel I can talk openly in this retrospective
I am satisfied with the last iteration
I am happy with the quality of our code
I think our continuous integration process is mature
Watch the constellations unfold. Afterwards ask which constellations were surprising. This can also be a closing activity (#53).

Hang up two flip charts, one headed 'I like' and the other 'I wish'. Give the participants 5-10 minutes to silently write down what they liked about the past iteration and the team and what they wish was different (and how it should be different) – one point per sticky note. When everyone is finished, go around the circle and everybody reads out their 'I like' items and hangs them up. Repeat the same for the 'I wish' stickies. Either debrief or use the stickies as input for the next phase.
Different parties present manifestos for change. Who will get your vote? Source: Thomas Guest
Is there an election coming up in your country? Use it as a back drop for your team to convince each other of their change initiatives.
Ask the participants to split into political parties with 2 or 3 members. For 20 minutes, each party will work on a manifesto for change. What isn't working? How would they improve things? Afterwards the parties meet again and their leaders present their manifestos. Be prepared for tough questions and heckling! Now plan for a better world! Summarise the manifestos with sticky notes, one color per party. What do the parties agree on? Which promises are unrealistic and which can you achieve?
Prepare a flip chart with 3 columns titled 'What', 'Who', and 'Due'. Ask one participant after the other, what they want to do to advance the team. Write down the task, agree on a 'done by'-date and let them sign their name. If someone suggests an action for the whole team, the proposer needs to get buy-in (and signatures) from the others.
Prepare 3 flip chart papers titled 'Helped', 'Hindered', and 'Hypothesis' (suggestions for things to try out). Ask participants to help you grow and improve as a facilitator by writing you sticky notes and signing their initials so that you may ask questions later.
