Heuristic evaluation is a usability inspection method for computer software that helps identify usability issues in the user interface (UI). It is a usability evaluation method that involves evaluating the user interface against a set of established usability principles (the "heuristics"). The goal of heuristic evaluation is to identify any usability issues in the UI, so they can be addressed and the product can be improved.

Heuristic evaluation is typically conducted by a small team of usability experts who work independently to evaluate the product. Each expert evaluates the product against a set of heuristics, and any issues they identify are recorded. The results of the evaluation are then discussed as a group, and a report is prepared that summarizes the findings and recommendations for improvement.

Heuristic evaluation is a useful method for identifying usability issues early in the design process, as it can be conducted relatively quickly and inexpensively. It is most effective when used in combination with other usability evaluation methods, such as usability testing with real users.
