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?
Find the source of problems whose origins are hard to pinpoint and lead to endless discussion Source:
Write the problem you want to explore on a sticky note and put it in the middle of a whiteboard. Find out why that is a problem by repeatedly asking 'So what?'. Find out the root causes by repeatedly asking 'Why (does this happen)?' Document your findings by writing more stickies and showing causal relations with arrows. Each sticky can have more than one reason and more than one consequence Vicious circles are usually good starting points for actions. If you can break their bad influence, you can gain a lot.
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!
Gauge participants' satisfaction with the retro on a scale from 1 to 5 in minimum time Source:
ALE 2011, Corinna Baldauf
Put sticky notes on the door with the numbers 1 through 5 on them. 1 is the topmost and best, 5 the lowest and worst.When ending the retrospective, ask your participants to put a sticky to the number they feel reflects the session. The sticky can be empty or have a comment or suggestion on it.
