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).
Which things are clear and feel good and which feel vague and implicit? Source: Katrin Dreyer
Use this activity if you suspect the team to make lots of unconscious decisions hardly ever questioning anything. You can figure out what things need to be talked about to get an explicit grasp of them.
about 3 metres of string as the clothesline
about 20 clothes pins
a white shirt (cut from paper)
a pair of dirty pants (cut from paper)
Hang up the clothesline and mark the middle, e.g. with a ribbon. Hang up the clean shirt on one side and the dirty pants on the other. Ask the team now to write items onto index cards for each of the categories. Hang up the notes with clothespins and re-arrange them into clusters. Now the team picks 2 'dirty' and 2 'clean' topics they want to talk about, e.g. by dot voting.
Asking and answering go around the team circle - an excellent way to reach consensus Source: Agile Retrospectives
Everyone sits in a circle. Begin by stating that you'll go round asking questions to find out what you want to do as a group. You start by asking your neighbor the first question, e.g. 'What is the most important thing we should start in the next iteration?' Your neighbor answers and asks her neighbor a related question. Stop when consensus emerges or the time is up. Go around at least once, so that everybody is heard!
Gauge participants' satisfaction with the retro on a scale from 1 to 5 in minimum time Source: ALE 2011, Corinna Baldauf
Put sticky notes on the door with the numbers 1 through 5 on them. 1 is the topmost and best, 5 the lowest and worst.When ending the retrospective, ask your participants to put a sticky to the number they feel reflects the session. The sticky can be empty or have a comment or suggestion on it.
