Heuristic Evaluation
What is Heuristic Evaluation in User Research?
Heuristic evaluation is a usability inspection method where experts analyze a user interface against a set of predefined usability principles or heuristics to identify potential usability issues.
Synonyms: Expert review, Usability inspection, Nielsen's heuristics, UX heuristics, Interface evaluation
How Heuristic Evaluation Works in UX Design
Heuristic evaluation involves a small group of usability experts examining a product's interface and judging its compliance with recognized usability principles, often referred to as heuristics. These evaluators work independently to identify potential usability problems, which are then compiled into a comprehensive list for the design team to address.
Benefits of Heuristic Evaluation in User Research
Heuristic evaluation offers several advantages in the user research process:
- Cost-effective: It requires fewer resources compared to full user testing.
- Quick turnaround: Results can be obtained relatively quickly.
- Identifies major issues: It often uncovers significant usability problems early in the design process.
- Complements user testing: It can be used in conjunction with other research methods for a more comprehensive evaluation.
Common Heuristics Used in UX Evaluation
While various sets of heuristics exist, Nielsen's 10 Usability Heuristics are widely used:
- Visibility of system status
- Match between system and the real world
- User control and freedom
- Consistency and standards
- Error prevention
- Recognition rather than recall
- Flexibility and efficiency of use
- Aesthetic and minimalist design
- Help users recognize, diagnose, and recover from errors
- Help and documentation
Frequently Asked Questions
- What's the difference between heuristic evaluation and user testing?: Heuristic evaluation is performed by experts based on established principles, while user testing involves actual users interacting with the product.
- How many evaluators are needed for a heuristic evaluation?: Typically, 3-5 evaluators are recommended to identify most usability issues.
- Can heuristic evaluation replace user testing?: No, it's best used as a complement to user testing, not a replacement. Each method uncovers different types of issues.
- When should heuristic evaluation be conducted in the design process?: It's often done early in the design process to catch major issues before user testing, but can be valuable at any stage.
