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....

An important goal of test and evaluation is to understand not only how a system performs in its intended environment, but also users’ experiences operating the system. This briefing aimed to provide the audience with a set of tools – most notably, surveys – that are appropriate for measuring the user experience. DOT&E guidance regarding these tools is highlighted where appropriate. The briefing was broken into three major sections: conceptualizing surveys, writing survey items, and formatting surveys....
