Categorize stories in 2 dimensions to identify boring ones Source:
Wayne D. Grant
Draw a big square and divide it into 2 columns. Label them 'Interesting' and 'Dull'. Let the team write down everything they did last iteration on stickies and put it into the appropriate column. Have them add a rough estimate of how long it took on each of their own stickies. Now add a horizontal line so that your square has 4 quadrants. Label the top row 'Short' (took hours) and the bottom row 'Long' (took days). Rearrange the stickies in each column. The long and dull stories are now nicely grouped to 'attack' in subsequent phases.
Get a sense of everyone's position and reach consensus Source:
When the team can't decide between two options, create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as option A) and the other as option B). Team members position themselves on the scale according to their preference for either option. Now tweak the options until one option has a clear majority.
Check satisfaction with retro results, fair distribution of talk time & mood Source:
Prepare a flip chart with a co-ordinate plane on it. The Y-axis is 'Satisfaction with retro result'. The X-axis is 'Equal distribution of talking time' (the more equal, the farther to the right). Ask each participant to mark where their satisfaction and perceived talking time balance intersect - with an emoticon showing their mood (not just a dot). Discuss talking time inequalities (and extreme moods).
