Whenever a firm lists its requirements for any system, be it for the management of fuel, maintenance, or real-time tracking of assets in the field, that list typically revolves around two basic ideas: record keeping and control. We want to make sure certain things get done at certain times, some things only happen under specific conditions, and reports exist to account for whatever has already occurred. Spec requirements often specify the exact reports the fleet managers look for and how operations are to be conducted, but they rarely detail how exceptions are to be handled.
