Draw a table with 3 columns. Head the first one 'Destination', the second one 'Delay' and the last one 'Announcement'.
Introduce the scenario: 'You are at a train station. Where is your train going? (It can be anything, a fictional or a real place.) How much of a delay does the train currently have? And what is the announcement? Why is there a delay? (This can be a real reason or modeled after the typical announcements.)'
Each team member fills out 3 sticky notes, 1 for each column. Going around the circle, each team member posts their notes and explains briefly, why they're going to destination X and why there's a delay (or not).
Trains and train delays are very familiar in Germany. Depending on your country and culture you might want to pick a different mode of transportation.
Group discussion with varying subsets of participants Source:
Place at least 4 and at most 6 chairs in a row so that they face the group. Explain the rules:
Take a bench seat when you want to contribute to the discussion
One seat must always be empty
When the last seat is taken, someone else must leave and return to the audience
Get everything going by sitting on the 'bench' and wondering aloud about something you learned in the previous phase until someone joins. End the activity when discussion dies down. This is a variant of 'Fish Bowl'. It's suited for groups of 10-25 people.
Condense many possible actions down to just two the team will try Source:
Lydia Grawunder & Sebastian Nachtigall
Hand out index cards and markers. Tell everyone to write down the two actions they want to try next iteration - as concretely as possible (SMART). Then everyone pairs up with their neighbor and both together must merge their actions into a single list with two actions. The pairs form groups of 4. Then 8. Now collect every group's two action items and have a vote on the final two.
Gauge participants' satisfaction with the retro on a scale from 1 to 5 in minimum time Source:
ALE 2011, Corinna Baldauf
Put sticky notes on the door with the numbers 1 through 5 on them. 1 is the topmost and best, 5 the lowest and worst.When ending the retrospective, ask your participants to put a sticky to the number they feel reflects the session. The sticky can be empty or have a comment or suggestion on it.
