Create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as 'Great' and the other as 'Bad'. Let participants stand on the scale according to their satisfaction with the last iteration. Psychologically, taking a stand physically is different from just saying something. It's more 'real'. You can reuse the scale if you close with activity #44.
Brainstorm what to repeat and what behaviours to avoid Source: Luis Goncalves
Head 2 flip charts with 'Repeat' and 'Avoid' respectively. The participants write issues for the columns on sticky notes - 1 per issue. You can also color code the stickies. Example categories are 'People', 'Process', 'Technology', ... Let everyone read out their notes and post them to the appropriate column. Are all issues unanimous?
Divide a flip chart into boxes headed with 'Start', 'Continue' and 'Stop'. Ask your participants to write concrete proposals for each category - 1 idea per index card. Let them write in silence for a few minutes. Let everyone read out their notes and post them to the appropriate category. Lead a short discussion on what the top 20% beneficial ideas are. Vote on it by distributing dotsor X's with a marker, e.g. 1, 2, and 3 dots for each person to distribute. The top 2 or 3 become your action items.
