Surface shared traits and mutual interests among team members Source:
This is an excellent activity for newly formed teams of 6 to 15 members. It speeds up team building by sharing traits and interests so that team members can build closer bonds than possible with just work-related stuff.
Have the team form a circle with everyone looking inwards. Leave about a foot of space between people. Depending on what you want to stress with this activity, you can ask colleagues that usually work remotely to stand about 5 feet away from the circle.
Hand a ball of yarn to a random player and tell them to hold on tight to the end of the yarn with their non-dominant hand and the ball in the dominant one. The yarn holder starts the game by saying something about themselves that is not work-related such as 'I have a daughter' or 'I play the guitar'. If this statement is true for any other team member they raise their hand and say 'Yes, that's me'. The yarn holder passes the ball to the person who raised their hand. If there's more than one, the yarn holder can choose one. If no one shares the statement the yarn holder has to make another statement.
The person who received the ball of yarn holds on to the thread and tautens it. This is the first connection in a network of shared traits. The new yarn holder now makes a statement about themselves, passes the ball while holding on to their part of the yarn and so on.
The game ends when time is up OR everybody has at least two connections OR the yarn runs out.
You can debrief with some of these questions:
What did you notice?
If you've got remote people: How does it feel to stand apart? How does it feel to have someone stand apart?
How do you feel about few (or no) connections?
What is it like to see this web of connections?
Can you be a team without this web?
What would happen if someone let go of their threads? How would it affect the team?
Is there anything you will do differently at work now?
Collect some news headlines in advance and take them to the retrospective to serve as examples. Try to gather a mixture of headlines: factual, opinion, review. Place the headlines where everyone can see them. Hand out sticky notes. Give team members 10 minutes to come up with their own headlines describing newsworthy aspects of the sprint. Encourage short, punchy headlines. Stick the completed headlines to a whiteboard. If any cover the same news item, combine them. If any are unclear, ask the reporter for details. Vote on which news items to discuss and analyse in more depth.
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!
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.
