Distribute index cards and markers. Set a topic, e.g. one of the following:
How did you feel during the iteration?
What was the most remarkable moment?
What was the biggest problem?
What did you long for?
If the last iteration had been a circus performance, what part did you play? Juggler, funambulist, clown, knife-thrower, ...
Ask the team members to draw their answer. Post all drawings on a whiteboard. For each drawing let people guess what it means, before the artist explains it. Metaphors open new viewpoints and create a shared understanding.
Participants write down significant events and order them chronologically Source: Agile Retrospectives
Divide into groups with 5 or less people each. Distribute cards and markers. Give participants 10min to note down memorable and / or personally significant events. It's about gathering many perspectives. Consensus would be detrimental. All participants post their cards and order them. It's okay to add cards on the fly. Analyze. Color Coding can help to see patterns, e.g.:
If your boss had witnessed the last iteration, what would she want you to change? Source: Love Agile
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.
Check for resistance instead of approval Source: Georg Paulus, Siegfried Schrotta \& Erich Visotschnig via Corinna Baldauf
Do you have a hotly debated matter with several possible ways to go and the team can't agree on any of them? Instead of trying to find a majority for a way that will create winners and losers, try what happens if you turn the decision inside out: Draw a table with the voters in the left-most column and proposals on top. Now everybody has to fill in their resistance towards each proposal. 0 means 'no resistance - this is what I want', up to 10, meaning 'shoot me now'. Give the least hated solution a try.
Walk through each story handled by the team and look for possible improvements Source: Corinna Baldauf
Preparation: Collect all stories handled during the iteration and bring them along to the retrospective. In a group (10 people max.) read out each story. For each one discuss whether it went well or not. If it went well, capture why. If not discuss what you could do differently in the future. Variants: You can use this for support tickets, bugs or any combination of work done by the team.
