Worldcon Division Head

A division head for a Worldcon is in a difficult and immensely important position which doesn't have a parallel in regional conventions -- though some have a layer called "division heads". The DH is at once the line manager in charge of a group of areas while simultaneously, along with the other DHs and the officers of the convention, being responsible for building the convention. This split responsibility -- on the one hand responsible for fairly specific deliverables, yet on the other hand, taking responsibility for the good of the con as a whole -- is tricky to manage and a skill which few have an opportunity to develop elsewhere in fandom.
