Cognitive walkthrough
Cognitive Walkthrough is a theoretical usability inspection method measuring easiness of interaction with system.

Preparation for the expertise falls into the following stages:

1. Users and contexts definition

  • identification of the general target audiences (TA) attributes
  • identification of usability goals of the TA
  • identification of users roles vs. goals, ranking of goals importance for users
  • identification of functionality options necessary for meeting TA goals and objectives; ranking of functionality attributes dependant on how well they help to reach goals
  • identification of the product's application options

2. Creation of user scenarios

  • development of the product's application scenarios
  • description of the path followed by the user within the product's structure

Once the application scenarios are developed, the expert follows them, rates easiness of tasks completion and records all errors.
