Test Metrics

Usability.gov lists several most helpful metrics:

Successful Task Completion.

Critical Errors

Non-Critical Errors

Error-Free Rate: Error-free rate is the percentage of test participants who complete the task without any errors.

Time On Task

Subjective Measures: These evaluations are self-reported participant ratings for satisfaction, ease of use, ease of finding information, etc where participants rate the measure on a 5 to 7-point Likert scale.

Likes, Dislikes and Recommendations: Participants provide what they liked most about the site, what they liked least about the site, and recommendations for improving the site.

What users say versus what users do are two completely different things, and the only way to verify is to test. Usability testing is more than a just a checkbox on a list of product requirements — it is the most convincing support for your design decisions. 📔 The Guide to Usability Testing
