Everyone in the team states their goal for the retrospective, i.e. what they want out of the meeting. Examples of what participants might say:
I'm happy if we get 1 good action item
I want to talk about our argument about unit tests and agree on how we'll do it in the future
I'll consider this retro a success, if we come up with a plan to tidy up $obscureModule
[You can check if these goals were met if you close with activity #14.]
[The Meet - Core Protocol, which inspired this activity, also describes 'Alignment Checks': Whenever someone thinks the retrospective is not meeting people's needs they can ask for an Alignment Check. Then everyone says a number from 0 to 10 which reflects how much they are getting what they want. The person with the lowest number takes over to get nearer to what they want.]
Set up a 'retrospective mailbox' at the beginning of the iteration. Whenever something significant happens or someone has an idea for improvement, they write it down and 'post' it. (Alternatively the 'mailbox' can be a visible place. This can spark discussion during the iteration.) Go through the notes and discuss them. A mailbox is great for long iterations and forgetful teams.
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!
Let team members appreciate each other and end positively Source:
Agile Retrospectives who took it from 'The Satir Model: Family Therapy and Beyond'
Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
