Dig out the stinky fish.
βΉοΈThis Retrospective is not easy and should only be done when the psychological safety in the team is high, and the team has already been working together for some time.
Also, I would not do the retro with a clear goal.
For example: Team or Project Changes, Role Changes, organisational changes can be reasons for this retro. Prepare your team upfront, so they have enough time to think about their fears related to the team and the organisation.
This template is a remix of the "Stinky Fish Retro" by Hyper Island and the "Anxiety Party" by Joe Fitzpatrick.
