Distribute index cards and markers. Set a topic, e.g. one of the following:
How did you feel during the iteration?
What was the most remarkable moment?
What was the biggest problem?
What did you long for?
If the last iteration had been a circus performance, what part did you play? Juggler, funambulist, clown, knife-thrower, ...
Ask the team members to draw their answer. Post all drawings on a whiteboard. For each drawing let people guess what it means, before the artist explains it. Metaphors open new viewpoints and create a shared understanding.
Create a histogram on how well ritual meetings went during the iteration Source:
Prepare a flip chart for each meeting that recurs every iteration, (e.g. the Scrum ceremonies) with a horizontal scale from 1 ('Did not meet expectations') to 5 ('Exceeds Expectations'). Each team member adds a sticky note based on their rating for each of these meetings. Let the team discuss why some meetings do not have a rating of 5. You can discuss improvements as part of this activity or in a later activity such as Perfection Game (#20) or Plus \& Delta (#40).
What would make the next iteration a perfect 10 out of 10? Source:
Prepare a flip chart with 2 columns, a slim one for 'Rating' and a wide one for 'Actions'. Everyone rates the last iteration on a scale from 1 to 10. Then they have to suggest what action(s) would make the next iteration a perfect 10.
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!
Let team members appreciate each other and end positively Source:
Agile Retrospectives who took it from 'The Satir Model: Family Therapy and Beyond'
Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
