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.
If we had ruined the last iteration what would we have done? Source:
You start the activity by asking: 'If we had completely ruined last iteration what would we have done?' Record the answers on a flip chart. Next question: 'What would be the opposite of that?' Record it on another flip chart. Now ask participants to comment the items on the 'Opposite'-chart by posting sticky notes answering 'What keeps us from doing this?'. Hand out different colored sticky notes to comment on the comments, asking 'Why is it like this?'.
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:
