What to never do in whiteboard sessions

If you want an engaging process, where people are actually smarter and better together, never have one person control the marker, no matter how smart or important they or others think they are. Make sure everyone records everything they think and say. If you want to cluster and sequence ideas later it's faster to use cards on a table as the whiteboard. This approach reduces and often completely eliminates dominating, disappearing and derailing. It keeps everyone optimally involved.
