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.
Explain an example of Value Stream Mapping. (If you're unfamiliar with it, check out this video or this printable 1-pager.) Ask the team to draw a value stream map of their process from the point of view of a single user story. If necessary, ask them to break into small groups, and facilitate the process if they need it. Look at the finished map. Where are long delays, choke points and bottlenecks?
Asking and answering go around the team circle - an excellent way to reach consensus Source:
Everyone sits in a circle. Begin by stating that you'll go round asking questions to find out what you want to do as a group. You start by asking your neighbor the first question, e.g. 'What is the most important thing we should start in the next iteration?' Your neighbor answers and asks her neighbor a related question. Stop when consensus emerges or the time is up. Go around at least once, so that everybody is heard!
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.
