Collect what team members perceived as good, bad and non-optimal Source: Manuel Küblböck
Put up three sections labeled ‘The Good’, ‘The Bad’ and ‘The Ugly’. Give everyone 5 minutes to note down one or more things per category from the last sprint. One aspect per post-it. When the time is up, have everyone stick their post-its to the appropriate labels. Cluster as you collect, if possible.
