Similar to any other meeting, a facilitated session needs some ground rules. The rules help participants understand what is expected, to focus on what’s important, and to help the facilitator to keep things on track. There are several ways to establish ground rules (also referred to as norms).
When the group establishes their own norms, they are more likely to follow them. When the facilitator sets the norms, the participants may consider them optional.
If the group establishes norms but they miss something significant that the facilitator knows may help them (such as listening when other people are talking), they can suggest it and then ask for participants to share their thoughts on the idea.
