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.
Collect what team members perceived as good, bad and non-optimal Source:
Put up three sections labeled ‘The Good’, ‘The Bad’ and ‘The Ugly’. Give everyone 5 minutes to note down one or more things per category from the last sprint. One aspect per post-it. When the time is up, have everyone stick their post-its to the appropriate labels. Cluster as you collect, if possible.
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.
Ideas for actions compete for 2 available 'Will do'-slots Source:
[Caution: This game creates 'winners' and 'losers'. Don't use it if the team has power imbalances.]
Ask everyone to think of 2 changes they'd like to implement and write them down on separate index cards. Draw 2 slots on the board. The first team member puts their favorite change idea into the first slot. His neighbor puts their favorite into the second slot. The third member has to pitch her favorite idea against the one already hanging that she favors less. If the team prefers her idea, it's swapped against the hanging one. This continues until everyone has presented both their cards.
Try not to start the circle with dominant team members.
Recognize the efforts of teammates and self-improve a little Source:
Put up 2 columns on a white board: 'Thank you!' and 'My action'. Ask everybody to write one sticky per column: Something they want to thank another teammate for doing; and something they want to change about their own behavior in the next iteration. It can be something really small. Once everyone is finished, do a round for each person to present their stickies and post them to the board.
