Secondary Tasks and Workload Measurement
The need for a theory and measurement strategy for workload arises from the growing number of activities in which a human operator is assigned jobs of monitoring, supervisory control, clerical activities and problem solving as opposed to activities involving physical effort. As systems become more automated the question of function allocation and allocation of personnel to jobs requires answers to questions, such as “How much can a person do?” or “How demanding is this job?”
