Explain an example of Value Stream Mapping. (If you're unfamiliar with it, check out this video or this printable 1-pager.) Ask the team to draw a value stream map of their process from the point of view of a single user story. If necessary, ask them to break into small groups, and facilitate the process if they need it. Look at the finished map. Where are long delays, choke points and bottlenecks?
Condense many possible actions down to just two the team will try Source:
Lydia Grawunder & Sebastian Nachtigall
Hand out index cards and markers. Tell everyone to write down the two actions they want to try next iteration - as concretely as possible (SMART). Then everyone pairs up with their neighbor and both together must merge their actions into a single list with two actions. The pairs form groups of 4. Then 8. Now collect every group's two action items and have a vote on the final two.
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.
