The document discusses various methods for inspecting products for usability, including heuristic evaluation, heuristic estimation, cognitive walkthrough, pluralistic walkthrough, feature inspection, consistency inspection, standards inspection, and formal usability inspection. Heuristic evaluation involves usability specialists evaluating a product's dialog elements against usability "heuristics." Cognitive walkthrough simulates how a user would solve problems by stepping through each dialog step. Pluralistic walkthrough involves users, developers, and human factors experts discussing each dialog element. Formal usability inspection combines individual and group inspections using a structured six-step process.
