What they do before the meeting is as important as the meeting itself.
They should make sure the agenda (the list of things to be discussed ) is complete by asking those involved what should be on it and then circulating (distributing) it to everyone concerned.
They should check the venue, making sure the room will be free, without interruptions, until the end of the meeting.
The chair should make sure that each participant has the chance to make their point, and should deal tactfully with disagreements, making sure that each side feels their point of view has been noted.
tactfully : 재치있는
미팅이 끝나고
At the next meeting, the chair should ask for the minutes to be read out and see if all agree that it is an accurate record of what happened, and see if there are any matters arising(any points from the last meeting that need to be discussed).
