FAQPage Schema
How do I run a UX heuristic evaluation on my interface?

A UX heuristic evaluation audits your interface against Nielsen's 10 heuristics and Krug's principles to surface actionable usability issues. It outputs a structured list of problems with severity scores and rationale for each violation found.

What usability issues can a Nielsen heuristics audit identify?

A Nielsen heuristics audit identifies usability issues where users struggle by evaluating interface elements against established design principles. It surfaces problems with severity scores and explicit justification for each detected heuristic violation.

Can I use this usability audit for both web and mobile interfaces?

Yes, this usability audit applies to both web and mobile interfaces. It evaluates interface usability against Nielsen's 10 heuristics and Krug's principles during design reviews, audits, and usability testing to identify user struggles.

How do I prioritize usability issues found during a design review?

You prioritize usability issues found during a design review using the severity scores provided in the structured output. Each identified violation receives a severity score and explicit rationale to help QA teams and UX designers triage.

What is the best way to evaluate an interface against Krug's principles?

The best way to evaluate an interface against Krug's principles is to perform a structured heuristic evaluation. This surfaces the highest-severity usability issues by analyzing the interface and providing actionable findings with severity scores.

Do I need a live application to perform a UX design review with heuristics?

A UX design review with heuristics evaluates interface usability during audits and usability testing. It analyzes the presented interface against Nielsen's 10 heuristics and Krug's principles to identify where users struggle and surface actionable issues.
