Facilitation Process Example.

<p>The facilitator stays with the same node throughout the day and discloses results and insights from previous groups’ discussion with each new group. For example, Group 1 works through the list of biodiversity and community ecology questions with the help of a facilitator. Group 2 then works with the same question list but is able to interact with Group 1’s ideas (but not vice versa) through the facilitator. Group 3 works with the original list again but is exposed to compounded ideas from Groups 1 and 2 through the facilitator, and so on until each group has an opportunity to discuss all six nodes.</p

Consensus-Building in Second Workshop.

<p>After sorting questions into each group (10–12 participants and a facilitator) are allotted 90 minutes to select the questions most pertinent to the node. The group then rotates to the next node.</p
