Usability: Test Types & Ethics
The document discusses different types of usability testing, including exploratory/formative testing which aims to understand why users have difficulties, and assessment/summative testing which evaluates how well a system performs. It also covers iterative design, validation/verification testing, and comparisons between systems. Usability testing should use representative samples of end users, observe them in actual work environments, and include interviews and measurements of performance. The goal is to recommend improvements and ensure ethical treatment of human subjects.
