eval-ux

To evaluate service usability using Nielsen heuristics, you observe the target interface and assign scores to each of the ten heuristics (H1–H10) to identify usability issues. This structured scoring framework systematically assesses screen states, consistency, and user control.

The severity rating scale used in a UX heuristic evaluation rates identified usability issues from 0 to 4 points. This severity taxonomy helps prioritize improvements by classifying the severity of each problem found during the interface assessment.

Yes, you can use this heuristic evaluation for mobile interfaces as well as web interfaces. The evaluation framework is designed to assess usability issues across both web and mobile platforms, identifying areas for improvement in either context.

You generate a UX evaluation report by summarizing the heuristic scores and severity ratings into a structured document. The report-generation workflow organizes the usability issues and improvement priorities, making it easy to share findings with your team.

The best way to prioritize UX improvements is by using the 0-4 severity rating taxonomy applied to each identified usability issue. This systematic scoring framework highlights critical interface problems and generates a prioritized list of improvements.

You do not strictly need web resource access, but the evaluation framework supports checking web resources when necessary. You can observe the target service's screens directly to apply the Nielsen heuristics and assess usability issues.
