Usability inspections are a set of methods for evaluating one interactive system by experts. They try to find possible usability problems and determining the level of usability of the system without involving real users. One of these methods is heuristic evaluation, where several experts inspect one system or its interface for searching usability issues. Some authors maintain that evaluation by experts in usability discovers more usability issues than evaluation conducted by non-experts. But the question is how to determine the degree of expertise of an evaluator.
