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.
Create actions based on how much control the team has to carry them out Source: Diana Larsen who adapted it from 'Seven Habits of Highly Effective People' by Stephen Covey and Circle of Influence and Concern' by Jim Bullock
Prepare a flip chart with 3 concentric circles, each big enough to put stickies in. Label them 'Team controls - Direct action', 'Team influences - Persuasive/recommending action' and 'The soup - Response action', from innermost to outermost circle respectively. ('The soup' denotes the wider system the team is embedded into.) Take your insights from the last phase and put them in the appropriate circle. The participants write down possible actions in pairs of two. Encourage them to concentrate on issues in their circle of influence. The pairs post their action plans next to the respective issue and read it out loud. Agree on which plans to try (via discussion, majority vote, dot voting, ...)
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.
