One of the first steps in organizing a conference is setting up the conference committee, with people responsible for all aspects of the event.
There are five key roles for any conference.
Depending on the size and scope of the conference, these chairs may set up committees to work with them.
Your conference may choose to establish committees to assist with specific functions. These committees are merely suggestions; feel free to establish the number and type of committees particular to the needs of a specific conference. Be sure to create a clear definition of roles and responsibilities and a reporting structure.
