The document summarizes various usability analysis techniques including heuristic evaluation, card sorting, contextual inquiry, personas, wireframing, and usability testing. Heuristic evaluation helps identify usability problems in interfaces. Card sorting explores how users group items to develop optimal structures. Contextual inquiry observes users performing tasks on-site. Personas represent different user types through fictional profiles. Wireframes depict navigational concepts at a basic visual level. Usability testing ensures intended users can efficiently complete intended tasks.
