See the King County Office of Emergency Management’s (OEM) attempt at doing this with short videos: “Emergency Operations Center (EOC) 101.”
Check them out — very basic, but then most people are “at the beginning of their EOC journey” and just need the very basics.
FYI, coincidentally, the current Disaster Zone podcast now playing is an interview with Brendan McCluskey, the King County OEM director, in which he talks about his operational concepts for an EOC and their latest $2 million technology upgrade: “Latest EOC Technology.” You are bound to learn something from listening to this podcast!
