Write down what you can never ever say out loud Source: Unknown, via Vanessa
Do you suspect that unspoken taboos are holding back the team? Consider this silent activity: Stress confidentiality ('What happens in Vegas stays in Vegas') and announce that all notes of this activity will be destroyed in the end. Only afterwards hand out a piece of paper to each participant to write down the biggest unspoken taboo in the company. When everyone's done, they pass their paper to their left-hand neighbors. The neighbors read and may add comments. Papers are passed on and on until they return to their authors. One last read. Then all pages are ceremoniously shredded or (if you're outside) burned.
Asking and answering go around the team circle - an excellent way to reach consensus Source: Agile Retrospectives
Everyone sits in a circle. Begin by stating that you'll go round asking questions to find out what you want to do as a group. You start by asking your neighbor the first question, e.g. 'What is the most important thing we should start in the next iteration?' Your neighbor answers and asks her neighbor a related question. Stop when consensus emerges or the time is up. Go around at least once, so that everybody is heard!
A good debriefing deepens understanding, learning and sharing. Preparation: Download and assemble the Debriefing Cube and cards.
During the retrospective, roll the cube. Then draw a card from the category it shows and use it to prompt a discussion. Repeat as time permits.
This will broaden your debriefing options and is especially great for groups without a facilitator to enable them to effectively debrief on their own.
