Each person brainstorms individually for each of these 4 questions:
What I Loved
What I Learned
What I Lacked
What I Longed For
Collect the answers, either stickies on flip charts or in a digital tool if you're distributed. Form 4 subgroups, on for each L, read all notes, identify patterns and report their findings to the group. Use this as input for the next phase.
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.
Divide a flip chart in 3 sections titled 'More of', 'Same of', and 'Less of'. Ask participants to nudge your behaviour into the right direction: Write stickies with what you should do more, less and what is exactly right. Read out and briefly discuss the stickies section-wise.
