An organization meeting is the meeting when the committee begins its work. Only one item appears on the agenda for the organization meeting, the election of the chairs. The committee cannot be properly constituted until the chairs have been elected. That meeting is referred to as the organization meeting to indicate that no prior meetings have been held. Basically, it's the first meeting, at which the chairs are elected. Once the chairs are elected, the committee can proceed with its work as it sees fit.
