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. 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.
Participants write down significant events and order them chronologically Source: Agile Retrospectives
Divide into groups with 5 or less people each. Distribute cards and markers. Give participants 10min to note down memorable and / or personally significant events. It's about gathering many perspectives. Consensus would be detrimental. All participants post their cards and order them. It's okay to add cards on the fly. Analyze. Color Coding can help to see patterns, e.g.:
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.

Hand out index cards and markers. Tell everyone to write down the two actions they want to try next iteration - as concretely as possible (SMART). Then everyone pairs up with their neighbor and both together must merge their actions into a single list with two actions. The pairs form groups of 4. Then 8. Now collect every group's two action items and have a vote on the final two.
Let team members appreciate each other and end positively Source: Agile Retrospectives who took it from 'The Satir Model: Family Therapy and Beyond'
Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
