Boggs, George J., Warren, Robert E. and Lowther, Daniel R. (1993): Assessing Ergonomic Furniture in The Workplace. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 416-420.

“The selection of work center furniture is critical to the continued productivity of telecommunications workers in VDT-intensive environments. This paper describes the design three separate ergonomic studies, conducted over a period of six months, whose goal was to select ergonomic furniture in a working environment. The first study assessed user comfort and user perceptions of furniture features for each of eight adjustable worktables. The second study applied this same methodology to each of ten chairs. The third study consisted of ergonomically-oriented inspections and checklist ratings in the human factors laboratory for the eight adjustable worktables and the ten chairs. The results suggest that the three factors (user body discomfort, user perceptions of furniture features and ergonomic evaluation) are tapping different aspects of furniture usability. Each measure contributes to an informed selection decision, but should not be used in isolation. A careful consideration of the total configuration of measures may lead to better furniture selection.”

Warren, Robert E. (1992): Telephone Service Center Call Duration Improvement. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 202-206.

“Call handling duration in a telephone service center was substantially improved by providing users easier access to mainframe data systems. Switching from a system that allowed access to only one system at a time to one that provided a separate window for each system produced an estimated 7% improvement in call handling duration. The improvement was most marked for those calls which required multiple system access.”
