Number of participants: Any
Duration: 10-45 minutes
How to Play
Make two columns: one for “plus” and one for “delta” (the Greek symbol for change).
- Ask the group to reflect on what was positive or repeatable about an activity and capture their thoughts under the “plus” column.
- Ask the group then to brainstorm about what they would change about it, and capture these under the “delta” column.
This feedback method can apply to any activity, idea, work product, or action. By focusing on change as opposed to direct negatives, the group will be more likely to share its true assessment while also generating improvement ideas.
The earliest known use of the Plus/Delta activity is at The Boeing Co circa 1980.
