Conference calls are a great way to get information out to a group of people -- especially if distance is a factor -- but we have all suffered through pointless calls. So if you're looking to have or attend a conference call anytime soon, keep these rules in mind:
If you're questioning whether you should hold a call or not, don't have it.
Everyone knows what time the conference call is. Make sure you show up early -- being a minute late is too late.
Keep it to the point. Ten minutes should be the maximum length of any conference call.
Since it's only ten minutes long, make sure you give the person holding the call your undivided attention.
If you are holding the call, make sure you leave room and time for feedback for questions. The best thing about conference calls is that it is a back and forth. If you wanted to have a conversation without the nuances that audio can provide, an email would have sufficed.
If you need to talk to someone, pick up the phone and call them. Don't spend that time involving others in a call that isn't relevant to them.
