Heuristic evaluation is one of the most common types of expert reviews for Web sites. It was developed by Jakob Nielsen. In the book, The Design of Sites, by Douglas K. Van Duyne, James A. Landay, Jason I. Hong, the authors explain heuristic evaluations.
What Is a Heuristic Evaluation Van Duyne, Landay, and Hong write:
“The basic idea is to have three to five expert judges independently evaluate a site, using a list of usability heuristics or principles.“
How To Perform a Heuristic Evaluation Van Duyne, Landay, and Hong write:
“In a heuristic evaluation, the judges go through the site, often with a set of sample tasks as a guide, looking for violations of the heuristics. They note each violation and make a suggestion for fixing it. ... The judges also rate each violation with a level of severity. Severity levels are usually assessed on the basis of the expected customer impact and frequency of the violation.”
