Contrary to usability testing, expert evaluation is carried out without users being present. Website or software is evaluated using a number of heuristic criteria. Various aspects of navigation, visual presentation, interactivity and textual information are analyzed with special emphasis on critical aspects to user goal achievement. Expert evaluation is recommended if:
- User audience of your website is not extremely specialized;
- Functionality of the system is easily understandable;
- You need to discover the most generic usability faults of existing website / software;
- You are trying to discover issues, which require more in depth research.
