    determining an amount of the resource that is used by the activities in the activity list by calling a resource provider associated with the resource to which the resource list is directed; and

    in an event that the resource is insufficient to satisfy each of the activities in the activity list, identifying at least one activity for which there is an insufficient amount of the resource.
