One can not overstate how important it also is, that the public is suspended for this type of meetings. Meaning no gathering of material for self-aggrandizing or as ammunition for department warfare. No PR-stunts and no humiliation for gaps in knowledge. The person and ego has to be suspended for a moment and the "competition" of man go take a hike, replaced by a competition of ideas. Fairness has to be upheld, as in everyone in the round has to be a good sport and accept his/her idea to be less likely. Todays self-obsessed culture makes such a round nearly impossible, except - ironically for near anonymous internet forums.
