A cognitive walkthrough is a review technique where you construct task scenarios from a specification and get a user to role play the part of walking through the task. They act as if the interface was actually built and they (in the role of a typical user) was working through the tasks. Each step the user would take is scrutinize.

The Cognitive Walkthrough method is a usability inspection method used to identify usability issues in a piece of software or web site, focusing on how easy it is for new users to accomplish tasks with the system. The method is rooted in the notion that users typically prefer to learn a system by using it to accomplish tasks, rather than, for example, studying a manual. The method is prized for its ability to generate results quickly with low cost, especially when compared to usability testing, as well as the ability to apply the method early in the design phases, before coding has even begun.
