Instructions for running this play

  1. Draw two columns on a large surface: one column for “plus” and one column for “delta”.
  2. Ask participants to reflect on what was positive or worth repeating about an activity. Capture their thoughts under the “plus” column.
  3. Ask participants to brainstorm about what they would change about the activity if it was performed again. Capture their thoughts under the “delta” column.

Consider using Silent Storming and Affinity Mapping for step 2 and 3.
