A sheet on meeting roles from the University of Delaware’s Biden School says the facilitator “Acts as a traffic cop during meeting” and “Keeps the meeting on track.” The timekeeper “Reminds group when time is not used as planned.”
A guide from the University of North Carolina advises: “Assign the role of timekeeper to help the facilitator move the group through the agenda.” It explains: “Telling someone that their time has expired is always hard to do.”
