Time economies: allocate a specified amount of speaking time to each participant before the meeting (e.g. duration of the meeting divided by number of participants) and allow participants to donate minutes to other speakers who used all their time but have something important to say (if nobody is willing to donate an extra minute or two, it was obviously not important enough. Or the meeting time is simply used up).
Benefits:
- participants become more aware of the limited time available in the meeting and will prioritise what they really need to say
- endless monologues by certain people are no longer possible, unless many people want to hear them (or if certain people receive extra time from the start)
