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. Ask questions about people's observations, such as which constellations were surprising. This can also be a closing activity (#53).
Discuss the 12 agile principles and pick one to work on Source:
Print the principles of the Agile Manifesto onto cards, one principle per card. If the group is large, split it and provide each smaller group with their own set of the principles.
Explain that you want to order the principles according to the following question: 'How much do we need to improve regarding this principle?'. In the end the principle that is the team's weakest spot should be on top of the list.
Start with a random principle, discuss what it means and how much need for improvement you see, then place it in the middle. Pick the next principle, discuss what it means and sort it relatively to the other principles. You can propose a position depending on the previous discussion and move from there by comparison. Repeat this until all cards are sorted.
Now consider the card on top: This is presumeably the most needed and most urgent principle you should work on. How does the team feel about it? Does everyone still agree? What are the reasons there is the biggest demand for change here? Should you compare to the second or third most important issue again? If someone would now rather choose the second position, why?
Group discussion with varying subsets of participants Source:
Place at least 4 and at most 6 chairs in a row so that they face the group. Explain the rules:
Take a bench seat when you want to contribute to the discussion
One seat must always be empty
When the last seat is taken, someone else must leave and return to the audience
Get everything going by sitting on the 'bench' and wondering aloud about something you learned in the previous phase until someone joins. End the activity when discussion dies down. This is a variant of 'Fish Bowl'. It's suited for groups of 10-25 people.
Asking and answering go around the team circle - an excellent way to reach consensus Source:
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.
