When conducting an audio conference, it is important to designate one person as "moderator" to lead the call so it runs smoothly. The person you designate to moderate the conference call will ensure the meeting stays on track. Business professionals run very busy lives, so time is of the essence. As such, it is important to keep the meeting within the designated time slot to avoid conflicts with anyone’s schedule. This is especially important when there are a large number of people on the call. If all of your attendees want to share their input on the call, it can easily run over the allotted time frame. Having a moderator will make sure that everyone has an opportunity to talk an organized manner.
