Place a circle or sphere in the middle of a free space. Let the team gather around it. Explain that the circle is the center of approval: If they agree to a statement they should move towards it, if they don't, they should move as far outwards as their degree of disagreement. Now read out statements, e.g.
I feel I can talk openly in this retrospective
I am satisfied with the last iteration
I am happy with the quality of our code
I think our continuous integration process is mature
Watch the constellations unfold. Ask questions about people's observations, such as which constellations were surprising. This can also be a closing activity (#53).
Visualize how information flows in, out and around the team Source:
Is information not flowing as well as it needs to? Do you suspect bottlenecks? Visualize the ways information flows to find starting points for improvements. If you want to look at one specific flow (e.g. product requirements, impediments, ...) check out Value Stream Mapping (#79). For messier situations try something akin to Cause-Effect-Diagrams (#25). Look at the finished drawing. Where are delays or dead ends?
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.
Gauge participants' satisfaction with the retro on a scale from 1 to 5 in minimum time Source:
ALE 2011, Corinna Baldauf
Put sticky notes on the door with the numbers 1 through 5 on them. 1 is the topmost and best, 5 the lowest and worst.When ending the retrospective, ask your participants to put a sticky to the number they feel reflects the session. The sticky can be empty or have a comment or suggestion on it.
