Exclusive membership
Exclusive membership is ZopNight's rule that a resource can belong to only one resource group at a time. Together with the rule that a resource or group can be attached to only one schedule, it means every resource has exactly one source of start and stop instructions. Why it matters: Two groups or schedules giving a resource conflicting orders would make its running hours, and its cost, unpredictable.
