A cognitive walkthrough is a usability inspection method for examining how easily a new user can complete a specific task in an interactive system. This lesson explains the method’s purpose, preparation, and step-by-step evaluation questions.
A cognitive walkthrough is a structured inspection in which evaluators examine the steps a user must take to accomplish a task. Its central concern is learnability: can a new user work out what to do by using the interface, rather than relying on a manual or prior experience?
