This is a round-based activity. In each round you ask the team a question, they write down their answers (gives everyone time to think) and then read them out to the others. Questions proposed for Software Development teams:
When was the last time you were really engaged / animated / productive? What did you do? What had happened? How did it feel?
From an application-/code-perspective: What is the awesomest stuff you've built together? What makes it great?
Of the things you built for this company, which has the most value? Why?
When did you work best with the Product Owner? What was good about it?
When was your collaboration best?
What was your most valuable contribution to the developer community (of this company)? How did you do it?
Leave your modesty at the door: What is the most valuable skill / character trait you contribute to the team? Examples?
What is your team's most important trait? What sets you apart?
('Remember the Future' (#37) works well as the next step.)
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.
