Feelings Matter in Agile Retrospectives: one-word exercise
A 1 word retrospective is a technique that helps if a team is struggling with the way they collaborate, or if there are issues which are not dealt with. All team members state in 1 word how they feel about the sprint, and a discussion is facilitated. It is an effective way for the team to discuss what is hampering them, and agree on how to deal with it and get it out of the way.
