Create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as 'Great' and the other as 'Bad'. Let participants stand on the scale according to their satisfaction with the last iteration. Ask people what they notice.
Psychologically, taking a stand physically is different from just saying something. It's more 'real'.
You can reuse the scale if you close with activity #44.
Collect what team members perceived as good, bad and non-optimal Source:
Put up three sections labeled ‘The Good’, ‘The Bad’ and ‘The Ugly’. Give everyone 5 minutes to note down one or more things per category from the last sprint. One aspect per post-it. When the time is up, have everyone stick their post-its to the appropriate labels. Cluster as you collect, if possible.
What could sub-groups improve when interacting with others? Source:
Identify sub-groups within the participants that interacted during the iteration, e.g. developers/testers, clients/providers, PO/developers, etc. Give participants 3 minutes to silently write down what they think their group did that negatively impacted another group. One person should be part of one group only and write stickies for all groups they don't belong to - 1 sticky per issue.
Then in turn all participants read their stickies and give them to the corresponding group. The affected group rates it from 0 ('It was not a problem') to 5 ('It was a big problem'). Thus you get insights and shared understanding about problems and can select some of them to work on.
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!
A good debriefing deepens understanding, learning and sharing. Preparation: Download and assemble the Debriefing Cube and cards.
During the retrospective, roll the cube. Then draw a card from the category it shows and use it to prompt a discussion. Repeat as time permits.
This will broaden your debriefing options and is especially great for groups without a facilitator to enable them to effectively debrief on their own.
