Everybody sums up the last iteration in 3 words Source:
Ask everyone to describe the last iteration with just 3 words. Give them a minute to come up with something, then go around the team. This helps people recall the last iteration so that they have some ground to start from.
Create a histogram on how well ritual meetings went during the iteration Source:
Prepare a flip chart for each meeting that recurs every iteration, (e.g. the Scrum ceremonies) with a horizontal scale from 1 ('Did not meet expectations') to 5 ('Exceeds Expectations'). Each team member adds a sticky note based on their rating for each of these meetings. Let the team discuss why some meetings do not have a rating of 5. You can discuss improvements as part of this activity or in a later activity such as Perfection Game (#20) or Plus \& Delta (#40).
Hand out pens and paper. Pose the question 'What if the company / department / team was territory? What would a map for it look like? What hints would you add for save travelling?' Let participants draw for 5-10 minutes. Hang up the drawings. Walk through each one to clarify and discuss interesting metaphors.
Divide a flip chart into boxes headed with 'Start', 'Continue' and 'Stop'. Ask your participants to write concrete proposals for each category - 1 idea per index card. Let them write in silence for a few minutes. Let everyone read out their notes and post them to the appropriate category. Lead a short discussion on what the top 20% beneficial ideas are. Vote on it by distributing dots or X's with a marker, e.g. 1, 2, and 3 dots for each person to distribute. The top 2 or 3 become your action items.
Let team members appreciate each other and end positively Source:
