Heuristic Review

A Heuristic Review (Heuristic Evaluation) is a method used by experts to evaluate the user interface (UI) of existing websites, applications, or systems from a usability (ease of use) and user experience (UX) perspective. By applying multiple “heuristics”—that is, sets of evaluation criteria or guidelines—this method identifies problems in how easily and intuitively people can interact with the product, and then proposes improvements to enhance usability and clarity.


Key Characteristics of Heuristic Review

  1. Expert Assessment

    • Unlike usability testing, where real users perform tasks, a heuristic review involves specialists (such as UX designers, UI designers, or researchers) who examine the screens and functionalities based on their expertise.

  2. Evaluation Based on Heuristics (Guidelines)

    • One widely adopted example is Jakob Nielsen’s “10 Usability Heuristics.”

    • The UI is measured against specific benchmarks, such as “Do users always know where they are?” or “Does the system provide sufficient information when errors occur?”

  3. Short Time Frame and Low Cost

    • Compared to user testing or large-scale research, heuristic reviews generally require fewer resources and can uncover a significant number of interface issues in a relatively short period.

  4. Early Detection of Major Issues

    • This approach can often spot serious UI or UX problems early, helping you improve quality before release while keeping costs down.

  5. Focus on Actionable Improvements

    • Ideally, a heuristic review doesn’t just highlight issues but also offers suggestions for fixing them, making it easier for teams to reach consensus and clarify the design direction.


Nielsen’s 10 Usability Heuristics (Example)

  1. Visibility of System Status

    • Keep users informed about what is happening (e.g., loading, processing, or errors).

  2. Match Between System and the Real World

    • Speak the user’s language by using familiar words and concepts, avoiding technical jargon.

  3. User Control and Freedom

    • Allow users to easily undo or redo actions, particularly if they make a mistake.

  4. Consistency and Standards

    • Follow platform conventions and common patterns so that interactions feel familiar.

  5. Error Prevention

    • Design input fields and workflows to minimize the chance of mistakes in the first place.

  6. Recognition Rather Than Recall

    • Don’t force users to rely on memory; provide the necessary clues or instructions on the screen.

  7. Flexibility and Efficiency of Use

    • Offer shortcuts or features that speed up tasks for experienced users (e.g., power users).

  8. Aesthetic and Minimalist Design

    • Remove unnecessary elements; highlight what is truly important to avoid overwhelming users.

  9. Help Users Recognize, Diagnose, and Recover from Errors

    • Provide clear messages indicating what went wrong and how to fix it.

  10. Help and Documentation

  • Make user guides and troubleshooting information easily accessible when needed.


Typical Steps in Conducting a Heuristic Review

  1. Select the Evaluation Criteria

    • Choose whether to use well-established heuristics (like Nielsen’s) or your project’s own guidelines.

  2. Define Task Scenarios

    • Create representative user journeys to follow as you move through the interface.

  3. Expert Evaluation

    • Record UI/UX issues and potential improvements according to each heuristic.

    • Assign severity or priority to each issue so improvements can be addressed systematically.

  4. Reporting and Feedback

    • Compile findings and share them with the team to build a common understanding.

    • Refine the prototype or product design as needed, and consider re-evaluation if further changes are made.


Conclusion

Heuristic reviews involve evaluating UI and UX against defined usability principles (“heuristics”). They allow teams to assess ease of use from a user’s perspective, and they:

  • Require only minimal time and cost

  • Uncover critical issues early

  • Lead to targeted improvement proposals

Because heuristic reviews rely on the expertise of evaluators—rather than direct user input—they are often best combined with user testing for a more comprehensive view of UI/UX quality. By leveraging both methods, product teams can gain deeper insights and ensure a higher standard of usability and user satisfaction.
