Diamond of Participation
= facilitation methodology explained by Sam Kaner in his book.
Sam Kaner himself gives it the full title as the "Diamond of Participatory Decision-Making" (p.20) He credits the help of Lenny Lind, Catherine Toldi, Sarah Fisk and Duane Berger.
"The diamond is a map that points to three phases that groups pass through as they move from questions to insights. Groups begin with divergent thinking, sit for a while in the chaos and uncertainty of “The Groan Zone” and later move into convergent thinking."

The diamond of participation is elaborated in Art of Hosting circles to what is called the "8 breaths" model, with 7 small diamonds inside one large one.
