Human-System Interaction (HSI) is the study of interfaces between humans and technical systems. The Department of Defense incorporates HSI evaluations into defense acquisition to improve system performance and reduce lifecycle costs. During operational test and evaluation, HSI evaluations characterize how a system’s operational performance is affected by its users. The goal of this course is to provide the theoretical background and practical tools necessary to plan and evaluate HSI test plans, collect and analyze HSI data, and report on HSI results....

The purpose of this paper was to identify the shortcomings of a single-method approach to evaluating human-system interactions during operational testing and offer an alternative, multi-method approach that is more defensible, yields richer insights into how operators interact with weapon systems, and provides a practical implications for identifying when the quality of human-system interactions warrants correction through either operator training or redesign.
