Even in those organizations, there will be controlling and Q&A. Orgs being sloppy in one regard are often sloppy in another and probably gave down bad orders in the one direction _and in the other, too_. I organize smaller events, but you wouldn't believe the number of f-ups a bad manager can produce left and right. Often, the "ground crew" isn't even at fault - e.g. I had events where the ground crew was briefed to a standard timetable layout, although we had provided a timetable usable for them beforehand, having them fix a lot of things on the fly.
