What is a cognitive walkthrough?

• A. A technique used to evaluate a computer interface or software by breaking down and explaining the steps a user will take to accomplish a task
• B. A method for performance testing under load
• C. A formal code review technique
• D. A survey for user satisfaction

Answer: (A)

A cognitive walkthrough is a usability evaluation that focuses on how a user thinks through a task while interacting with an interface. Evaluators step through the task from the user’s perspective, breaking down each action needed to achieve the goal and asking at every step whether the user would know what to do next, whether the next action is clearly visible, and whether the cues, labels, and feedback will support the correct choice. The goal is to uncover where novices or unfamiliar users might be unsure, misinterpret cues, or struggle with the task flow, before a product is fully built or released.

This method is often done early in design with a prototype, emphasizing the user’s cognitive process rather than measuring performance metrics like speed or error rates. It helps identify ambiguous controls, unclear terminology, and missing or misleading prompts so the interface can be redesigned to align with users’ expectations and mental models.

It differs from performance testing under load, formal code reviews, or surveys, because those focus on system performance, code quality, or user satisfaction, whereas a cognitive walkthrough targets the understandability and discoverability of actions necessary to complete a task.
