Try requiring a second on an idea before the group spends time discussing it! In a convention or board meeting, when a motion is made, it must be seconded before it is discussed. This concept is a time saver. It requires that at least two people want to discuss an issue before the group will spend valuable group time on the issue. In meetings in business and industry, the term second may be too strong. Try simply asking if anyone else in the meeting wants to spend group time on the issue? Surely you have wasted time at a meeting discussing an issue that only one person appeared to care about! This technique will put a halt to that time waster.
