Abstract : In sustained operations, the cumulative effect of workload may lead to unpredicted, catastrophic human failure. Workload assessment, however, has suffered from the lack of an overall, standardized framework which would permit development of sensitive, predictive metrics. Such a general framework is developed in this paper, based on the view that workload is a multiply-determined hypothetical construct conveniently summarizing the interactions which limit task performance. Major task, operator, and response factors are presented, and related to metrics available or being developed for assessing these factors. The framework is then utilized to suggest the broad outlines of a research program leading to standardization of workload assessment in sustained operations environments.
