 Business Actor
  
    Does each (human) business actor express a role, not a
      person? Try to name at least two people that can act as the actor.Does each business actor model something outside the
      business?Is each business actor involved with at least one use case?
      If not, remove it.Does each business actor represent one role? If not, you
      should probably split the actor into several actors, each expressing a
      different role.Does each business actor have an explanatory name and
      description that is understandable to people outside the
      business-engineering team?
