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.]
If your team has a tendency to see obstacles outside of their team and influence and primarily wants others to change, you can try this activity:
Draw a big rectangle on the board and another rectangle inside of it, like a picture frame. Hang all complaints and grievances that surfaced in previous phases into the frame.
Now comes the interesting twist: Explain that if they want anything in the outside frame to change, they will have to do something themselves to affect that change. Ask the team to come up with actions they can do. Put these actions into the inner rectangle (near the outer sticky they are addressing).
