Before you start a meeting, you need to define the roles of the people involved. The most common roles are the facilitator, the note-taker, the timekeeper, and the participants. The facilitator is responsible for guiding the meeting process, ensuring everyone has a chance to speak, and keeping the meeting on track and on time. The note-taker is responsible for capturing the key points, decisions, and action items from the meeting. The timekeeper is responsible for monitoring the time and alerting the facilitator and the participants when the meeting is running over or under the allocated time. The participants are responsible for contributing to the meeting objectives, listening actively, and respecting the ground rules. You can train and coach others on these roles by explaining their purpose, benefits, and expectations, and by modeling them yourself in your own meetings.
