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.
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.)
Each team member explores one topic in depth in a series of 1:1 talks Source:
Each participant writes down one topic they want to explore, i.e. something they'd like to change. Then form pairs and spread across the room. Each pair discusses both topics and ponders possible actions - 5 minutes per participant (topic) - one after the other. After 10 minutes the pairs break up to form new pairs. Continue until everyone has talked to everyone else. If the group has an odd number of members, the facilitator is part of a pair but the partner gets all 10 minutes for their topic.
Gauge participants' satisfaction with the retro in minimum time using smilies Source:
Draw a ':)', ':|', and ':(' on a sheet of paper and tape it against the door. When ending the retrospective, ask your participants to mark their satisfaction with the session with an 'x' below the applicable smily.
