Everyone in the team states their goal for the retrospective, i.e. what they want out of the meeting. Examples of what participants might say:
I'm happy if we get 1 good action item
I want to talk about our argument about unit tests and agree on how we'll do it in the future
I'll consider this retro a success, if we come up with a plan to tidy up $obscureModule
[You can check if these goals were met if you close with activity #14.]
[The Meet - Core Protocol, which inspired this activity, also describes 'Alignment Checks': Whenever someone thinks the retrospective is not meeting people's needs they can ask for an Alignment Check. Then everyone says a number from 0 to 10 which reflects how much they are getting what they want. The person with the lowest number takes over to get nearer to what they want.]
State the topic that the team will explore in depth (deployment processes, peer-programming, Definition of Done, ...). Break the room into groups of 3-4 people each. Give them 5-7 minutes to list all contributing factors, drivers and actions that make up the topic. Go around the room. Each group reads 1 of their sticky notes and puts it up inside the force field until no group has any items left. Cluster or discard duplicates. Repeat the last 2 steps for factors that inhibit or restrain the topic from being successful or being as effective as it could be. Review all posted items. Add any that are missing.
To identify the most influential factors, everybody gets to 4 votes - 2 for contributing factors, 2 for inhibitors. Tally the votes and mark the top 2x2 factors with big arrows. Spend the last 15-20 mins of the session brainstorming ways to increase the top driving factors and decrease the top restraining factors.
Prepare a flip chart with 3 columns titled 'What', 'Who', and 'Due'. Ask one participant after the other, what they want to do to advance the team. Write down the task, agree on a 'done by'-date and let them sign their name. If someone suggests an action for the whole team, the proposer needs to get buy-in (and signatures) from the others.
Prepare 3 flip chart papers titled 'Helped', 'Hindered', and 'Hypothesis' (suggestions for things to try out). Ask participants to help you grow and improve as a facilitator by writing you sticky notes and signing their initials so that you may ask questions later.
