Heuristic Evaluation
A heuristic evaluation consists of an evaluation of a product or system against well-established usability guidelines, or “heuristics.” The outcome of a heuristic evaluation is the identification and prioritization of areas for improvement. A heuristic evaluation can include all of an application or site or just part of it.
Cognitive Walkthrough
A cognitive walkthrough analyzes the steps required of users to perform tasks with a product or system. The research team identifies user roles, and goal-oriented scenarios and tasks guide the analysis as reviewers role-play the part of users “walking through” the actual or prototyped product or system to complete tasks, identifying any usability obstacles they encounter. When paired with a heuristic evaluation, the cognitive walkthrough produces a powerful set of findings that allow the client to implement dramatic usability improvements in its product or site.
Expert Reviews
An expert review is an evaluation of your product or website by a user experience expert using widely accepted user experience heuristics, usability principles, and the deep industry experience of the individual performing the review. Expert reviews are typically a short project that clients find valuable as a complement to a lab study or as part of a larger user-centered design effort. At Blink, most expert reviews consist of two complementary parts: a heuristic evaluation and a cognitive walkthrough.
