Distribute blank index cards and tell the team they have 10 minutes to write a postcard to a person the whole team knows (i.e. an ex-colleague). When the time is up, collect and shuffle the cards before re-distributing them. Team members take turns to read out loud the postcards they got.
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.
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!
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.
