“ ... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested. ”

Becker, Ami B., Swanson, Naomi G., Sauter, Steven L., Galinsky, Traci L., Jones, Stephen and Schleifer, Lawrence (1995): Compatibility of Job Rotation Subtasks in Data Entry Work. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 965.

“A field study at the IRS Cincinnati Service Center (CSC) was undertaken in order to assess the feasibility and effectiveness of implementing a job rotation strategy to combat the negative consequences of continuous video display terminal (VDT) work. Baseline discomfort, fatigue, and mood state data were collected for each of two tasks separately: (1) the primary data entry task, and (2) document preparation, a clerical task in which operators prepare tax returns for scanning. The objective of the evaluation was to identify the stressors associated with each task, and thus determine whether a job rotation strategy involving document preparation could offset the psychological and physiological stress of prolonged VDT work. The results of the analyses indicated that while rotating to document preparation from terminal work may help to relieve visual discomfort, such a job rotation strategy may be ineffective in providing relief from other symptoms. The findings showed generally that document preparation and terminal work had similar, negative physical and psychological consequences for operators: Musculoskeletal discomfort, fatigue, and headache increased over the course of the workday, while positive affect decreased. These data corresponded with participants' responses to a follow-up survey; that is, they became increasingly uncomfortable as the day progressed and the breaks did not provide them with adequate time to recover from discomfort and fatigue. The results of a postural analysis provided confirmation that the tasks may be too similar for one to provide sufficient musculoskeletal relief from the other. Alternative job intervention strategies which may be useful in combating the stress and fatigue shared by the two tasks include a daily employee exercise program or the provision of more frequent, distributed restbreaks throughout the day. Testing of one such restbreak program is currently under way at the CSC.”
