Purpose
The method helps clarify group input, selection, and decision-making concretely. It turns individual contributions into a visible selection. The result is captured as a Venn Diagram, Overlap Notes, and Differentiators.
Facilitation
3-Circle Venn Diagram
Turns group contributions, selection, and decision-making into a tangible result by defining three perspectives, collecting items, and deriving implications.
Which items sit in which intersections of the three perspectives, and what implications follow for next decisions?
LowWorkshop + async15-45 min
How it works
The team follows the steps: define three perspectives, collect items, place items into areas, discuss overlaps, and derive implications. Each step is captured visibly. At the end, a Venn Diagram, Overlap Notes, and Differentiators are available so decisions, tests, or actions can follow directly.

Deep dive
In detail
3-Circle Venn Diagram follows a clear working logic: define three perspectives, collect items, place items into areas, discuss overlaps, and derive implications. This turns the method into a visible thinking process rather than only a conversation. The participants move step by step from raw material, observations, or options toward a shared structure. As a result, a Venn Diagram, Overlap Notes, and Differentiators support decisions, learning, or further planning.
Facilitation
Prepare a clear guiding question, the right information, and a visible workspace. Plan about 15-45 min with 2-8 people and use the format either in a workshop or asynchronously. The facilitation remains lightweight; short timeboxes, visible intermediate results, and a parking lot for open questions help.
