Facilitation is the process of enabling groups to work cooperatively and effectively.
Facilitation is often an important part of usability activities.
In particular, facilitation is important in circumstances where people of diverse backgrounds, interests and capabilities work together. It is important that all participants are aware of, and agree with, the purpose of the session. The purpose should be worded clearly and simply. Ideally it should be visible at all times so that participants can be reminded of it if necessary. A clear agenda helps focus participants on the work at hand, and helps the facilitator enforce time-keeping.
