Canadian mate Chris Corrigan has been doing some absolutely brilliant thinking about harvesting, and publishing much of it on his blog, “Parking Lot“.
His latest “Sense-making in a World Cafe” outlines a proposal for a World Cafe designed to harvest complexity. In it, Chris details a complex but very effective process that offers valuable clues for how to frame and manifest participant-driven evaluations/harvests.
A quick search for “harvesting” on Chris’ blog will yield rich results for all World Café hosts and other participatory practitioners. Start with his seminal piece on Harvesting as a verb and you’ll never look back!
