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.
We talked about what was most important to me
I spoke openly today
I think the time of the retrospective was well invested
I am confident we will carry out our action items
Watch the constellations unfold. Any surprising constellations? This can also be an opening activity (#52).
