You take the DeLorean back to the beginning of the project Source:
This activity is great for looking at a longer period of time. Put on your storyteller hat and ask your team to imagine the following scenario:
"You are sitting relaxed at your computer working, when suddenly there is a loud bang and a huge cloud of dust is in your room. You cough and as the dust settles, you realize that a car has driven through the wall of your house. You approach cautiously to see what has happened. The car looks futuristic and has gullwing doors. You wipe the dust off the windshield and realize: it's Marty McFly with his DeLorean. He seems unharmed, but is unconscious. You sense your chance and gently push Marty into the passenger seat. The time machine seems to be undamaged. You risk it and travel back to the beginning of your project: Greenfield. Not a single line of code has been written yet. Now you have the possibility to start again from scratch:
What do you definitely keep?
What do you do differently this time?
What were your biggest learnings?"
Give everybody 7 minutes to write down their ideas on sticky notes – 1 idea per sticky. When the time is up, the first person briefly presents their stickies for the first category and posts them on the board for this category. Then the second person presents and so on. Cluster as you go along. What themes do appear?
What would make the next iteration a perfect 10 out of 10? Source:
Prepare a flip chart with 2 columns, a slim one for 'Rating' and a wide one for 'Actions'. Everyone rates the last iteration on a scale from 1 to 10. Then they have to suggest what action(s) would make the next iteration a perfect 10.
Brainstorm what worked well & what to do differently and pick the top initiatives Source:
Head 2 flip charts with 'Worked well' and 'Do differently next time' respectively. 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.
Each participant notes 1 thing they like and 1 thing they'd change about the retro Source:
Prepare a flip chart with 2 columns: Head them with 'Plus' and 'Delta'. Ask each participant to write down 1 aspect of the retrospective they liked and 1 thing they would change (on different index cards). Post the index cards and walk through them briefly to clarify the exact meaning and detect the majority's preference when notes from different people point into opposite directions.
