The term workload can refer to a number of different yet related entities. However, it is clear that cognitive workload results from mental processes when performing tasks, depending on the users's capabilities and the task demands. ==An amount of labor== Workload is the amount of work an individual has to do.〔Jex, S. M. (1998). Stress and job performance: Theory, research, and implications for managerial practice. Thousand Oaks, CA: Sage.〕 There is a distinction between the actual amount of work and the individual's perception of the workload.〔 Workload can also be classified as quantitative (the amount of work to be done) or qualitative (the difficulty of the work).〔 The assessment of operator workload has a vital impact on the design of new human-machine systems. By evaluating operator workload during the design of a new system, or iteration of an existing system, problems such as workload bottlenecks and overload can be identified. As the human operator is a central part of a human-machine system, the correction of these problems is necessary for the operation of safe and efficient systems. An operating budget may include estimates of the expected workload for a specific activity. Work loads can vary in many different situations, but the average workload is average. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「workload」の詳細全文を読む スポンサード リンク
