Heuristic evaluation
<pageby nominor="false" comments="false"/>
Introduction
According to usability.gov, “A heuristic evaluation is a usability inspection method for computer software that helps to identify usability problems in the user interface (UI) design. It specifically involves evaluators examining the interface and judging its compliance with recognized usability principles (the "heuristics"). Heuristic evaluations usually are conducted by a small set (one to three) of evaluators. The evaluators independently examine a user interface and judge its compliance with a set of usability principles. The result of this analysis is a list of potential usability issues or problems. The usability principles, also referred to as usability heuristics, are taken from published lists. Ideally, each potential usability problem is assigned to one or more heuristics to help facilitate fixing the problem. As more evaluators are involved, more true problems are found.”

General heuristics
There exist several popular heuristics. However, these are not directly operational, i.e. they are guidelines for usability experts. Beginners rather should start with web usability guidelines checklists, i.e. do a guidelines-based review.
