Diamond of Participation
= facilitation methodology explained in a book by Sam Kaner.
"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." (http://chriscorrigan.com/parkinglot/?p=1265)
