Paradkar, Piyusha V. and Caldwell, Barrett S. (1995): Situation and User Experience Influences on Voice Mail System Performance Evaluations. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 829-833.

This paper presents results of a large evaluation of user perspectives on voice mail system performance as measured by message transmission delay. Over 1000 state employee respondents completed survey questions rating system speed (as presented in a standardized user interface questionnaire) and tolerance for message transmission delay in a variety of situational task contexts. Results of the study indicate that situation variables (message urgency, message context, and sender-receiver distance) affected user ratings of maximum acceptable transmission delay. In addition, user experience as measured by frequency of system use, but not length of exposure to the system, was a significant predictor of evaluations of what constituted acceptable voice mail message delivery performance. Users dynamically change their expectations and tolerances for "adequate" system performance based on system use and task demands. These results provide implications for future studies of diffusion of innovations and organizational implementation of new information technology systems.

Caldwell, Barrett S., Everhart, Nick C., Paradkar, Piyusha V. and Suh, Hyun-Suk (1995): Issues of Dependence and Reliance on Technological Advancement: Examples from American Football and Air Traffic Control. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 1194-1198.

This paper addresses aspects of dependence and reliance on new technologies, using American football and air traffic control as examples. Football has developed an audio communication system between the coach and quarterback in a hostile environment (auditory signal in a noisy stadium). Should technological breakdown occur, performance could suffer if the users are not proficient with backup systems (hand signals transmitted from the sideline). Dependence on technology takes a more serious form in air traffic control, as thousands of lives depend on technology performing as expected. Backup systems exist, but suffer from the same weaknesses as the existing system and cannot handle the volume of system activity. The possibility of technological failure needs to be considered before implementing and relying on new systems, and can often be mediated by careful and innovative thinking before new technology is adopted.
