  The activities involved in handling these interactions consume attention and require intervention by the human operator.

  Because the operators' attention is required also to other problem solving activities, these mental activities are error-prone. Also, if any of the mental activities described above fail, a new event might enter the system, and the system might enter an ambiguous or inconsistent state.
