An Insight About Group Meeting Size

We don’t have too many meetings.  We have far too many bad meetings.

Let’s talk about meetings where a decision needs to be made, or a problem reviewed, or a plan needs to be created.  Who do you invite to this meeting, and why?  What will each person contribute? 

My observation is that the number of people who will dominate a meeting is the square root of the number of participants.  If you have 4 people in the meeting, 2 of them will dominate.  If you have 9 people, 3 of them will dominate.  If you invite 25 people, 5 of them will dominate. 

It’s even more noticeable in virtual meetings, because the delays of video and audio make it more difficult for someone to “break in” to a conversation dominated by others.

This is not an iron-clad rule but it’s a frequent pattern. 

How to use this insight:

  • Smaller meetings are probably better in many cases
  • Use a small meeting to create a starting work product for a larger group to review
  • Take steps in the meeting to make sure everyone is heard
  • Keep discussions focused on topic – be willing to put less related ideas in a ‘parking lot’ for another time
  • Lay out your expectations before the meeting and as it begins, saying “We need everyone’s input here”
