The choice of moderator is critical to the success of any conference panel. Their primary purpose is to ask the panelists probing questions, focusing on providing useful information, exploring different opinions and uncovering valuable insights for the audience.
Just like a good dinner party host, the aim is to keep the discussion flowing without allowing any one person to dominate.
It is important that panelists prepare as well, not just show up. A good moderator will ask panelists what kinds of questions they think they should be asked, and get them to prepare short bullet points.
There is no need to re-hash bios. The aim is to create something on stage that couldn’t have happened if each person appeared individually.
