Heuristic evaluation is a practical way to inspect an interface for usability problems by comparing it with established usability principles. This lesson explains what the method is, when it is useful, and how evaluators can conduct it in a structured way.
A heuristic evaluation is a usability inspection method in which evaluators examine an interface and judge whether it follows recognized usability principles, called heuristics. Its main goal is to identify interface design problems that could make a product difficult or frustrating to use.

What is heuristic evaluation?
A usability inspection method in which evaluators examine an interface against recognized usability principles to identify design problems.
What is a use case in a heuristic review?
A typical user task used to judge whether an interface supports users' needs and preferences.
Why are multiple evaluators recommended?
Different evaluators may notice different problems. Nielsen recommended three to five; beyond five, added insights may not justify the extra cost.
Why inspect individually before discussing findings?
Independent inspection helps evaluators form their own observations and reduces the risk of group confirmation bias.
Name one strength and one limitation of heuristic evaluation.
It can uncover major usability issues quickly with relatively few logistical demands, but findings depend on evaluator expertise and are not hard performance data from users.
