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.
Collect some news headlines in advance and take them to the retrospective to serve as examples. Try to gather a mixture of headlines: factual, opinion, review. Place the headlines where everyone can see them. Hand out sticky notes. Give team members 10 minutes to come up with their own headlines describing newsworthy aspects of the sprint. Encourage short, punchy headlines. Stick the completed headlines to a whiteboard. If any cover the same news item, combine them. If any are unclear, ask the reporter for details. Vote on which news items to discuss and analyse in more depth.
If your boss had witnessed the last iteration, what would she want you to change? Source:
Imagine your boss had spent the last iteration - unrecognized - among you. What would she think about your interactions and results? What would she want you to change? This setting encourages the team to see themselves from a different angle.
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:
