Chairing a conference is much like running a meeting, only on a larger scale. A conference may run upwards of a day (maybe more) and involve multiple topics and speakers.
I was chairman of an organization for five years. In that time we held four in-person conferences. (The fifth was a teleconference.) I learned a lot chairing those meetings, which I’d like to share with you. This is not a comprehensive list by any means; just my observations from those conferences. Incidentally, many of the suggestions apply to regular meetings. Conferences can enhance and test your managerial skills, as you will see.
