Put up two posters labeled 'proud' and 'sorry'. Team members write down one instance per sticky note. When the time is up have everyone read out their note and post it to the appropriate poster. Start a short conversation e.g. by asking:
Did anything surprise you?
What patterns do you see? What do they mean for you as a team?
Hand out pens and sticky notes. Ask everyone for ideas on how to turn the next iteration / release into a certain desaster - one idea per note. When everyone's finished writing, hang up all stickies and walk through them. Identify and discuss themes. In the next phase turn these negative actions into their opposite.

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.
