Meetings follow a standard structure including opening, noting attendees, accepting previous minutes and agenda, discussing topics, any other business, and setting the next meeting date. Key roles are the chair who leads discussion, secretary who takes minutes, and attendees. Good meetings have a clear purpose and agenda communicated ahead of time, start and end on time, a comfortable room, focus on the agenda, and minutes recorded. Bad meetings have poor planning, lack preparation, poor timekeeping, and no decisions made.
