Each participant tells a story about the last iteration that contains certain words Source:
Provide everyone with something to write down their story. Then introduce the shaping words, which influence the story to be written:
If the last iteration could have been better: You set a couple of shaping words, e.g. such as 'mad, sad, glad' or 'keep, drop, add'. Additionally they have to write their story in first person. This avoids blaming others.
If the last iteration was successful: The team can either choose their own set of words or you can provide random words to unleash the team's creativity.
Now each participant writes a story of no more than 100 words about last iteration. They have to use each shaping word at least once. Timebox this to 5-10 minutes. When everyone's finished, they read out their stories. Afterwards lead a discussion about common themes of the stories.
Visualize promise and ease of possible courses of actions to help pick Source:
Reveal a previously drawn tree. Hand out round index cards and instruct participants to write down the actions they would like to take - one per card. When everyone's finished, collect the cards, shuffle and read them out one by one. Place each 'fruit' according to the participants' assessment:
Is it easy to do? Place it lower. Hard? More to the top.
Does it seem very beneficial? Place it more to the left. Value is dubious at best? To the right.
The straightforward choice is to pick the bottom left fruit as action items. If this is not consensus, you can either have a short discussion to agree on some actions or dot vote.
Let team members appreciate each other and end positively Source:
