A usability inspection method where evaluators examine an interface against a set of established usability principles called heuristics. Jakob Nielsen's 10 heuristics are the most widely used, covering issues like error prevention, user control, and consistency.
Common contexts
- Auditing a legacy product for usability issues before a redesign when user recruitment isn't immediately possible
- Running a structured evaluation with three to five UX reviewers to generate a prioritized list of issues for a client
- Providing rapid expert feedback on a competitor's interface to identify opportunities before a design sprint begins
Use when
When you need a fast, cost-effective way to surface a broad range of usability issues early in the process, or when user testing isn't feasible in the current timeline. Most effective with three to five evaluators working independently before comparing findings.
Avoid when
Don't use heuristic evaluation as a replacement for user testing — expert reviewers reliably find different issues than real users encounter, and skipping user testing in favor of heuristic review can give false confidence in a design's usability.
Heuristic evaluations are most valuable not for the issues they find but for the ones multiple evaluators independently flag — when three people hit the same heuristic violation independently, that's the one worth fixing before any user ever sees the screen.
Real-world examples
- Nielsen Norman Group routinely conducts heuristic evaluations of major product launches—evaluating interfaces against Jakob Nielsen's 10 usability heuristics—and publishes findings as industry-reference reports.
- The US government's Digital Analytics Program uses heuristic evaluation as part of the review process for federal agency websites before they go live on USA.gov.
- Intuit's design team uses heuristic evaluation as a rapid early-stage quality check on TurboTax UI changes, catching obvious usability violations before investing in full user testing sessions.
