Excerpt from Building Regenerative Communities: Open Space and World Café. (download the whole booklet here)

Open Space This is an open form of meeting where passion and responsibility are combined to empower participants by allowing agenda topics to arise from the group. A facilitator is only visible when the meeting needs re-opening. There are a series of laws or principles to consider with an “open space” meeting. Two of these are:  The law of two feet: If you find yourself in a situation where you are neither learning nor contributing, move somewhere where you can. This is a law like the law of gravity. You can choose to notice it or not, but it's safer just to notice it.  The four principles: Whoever comes are the right people; whatever happens is the only thing that could have happened; when it starts is the right time; and when it’s over, it's over. These aren't prescriptive—they are the results of thousands of little experiments.

The World Café Using seven design principles and a simple method, the World Café is a powerful social technology for engaging people in conversations that matter, offering an effective antidote to the fast-paced fragmentation and lack of connection in today's world. This approach to conversation creates several smaller, intimate groups within a larger group to discuss one question, thereby giving more people an opportunity to dialogue. Based on the understanding that conversation is the core process that drives personal, business, and organizational life, the World Café is more than a method, process or technique. It's a way of thinking and being together sourced in a philosophy of conversational leadership. http://www.theworldcafe.com/tools.html
