What are the most common usability testing metrics to improve your career in accessibility testing?

1 Effectiveness metrics

Effectiveness metrics are used to evaluate how well users can complete their tasks and goals with a product. They include measures such as success rate, error rate, and task completion time. These metrics can help you identify and prioritize the most critical issues that affect the accessibility of a product, such as navigation, readability, compatibility, and feedback. Effectiveness metrics can also help you compare different versions or alternatives of a product and determine which one performs better for different user groups.

2 Efficiency metrics

Efficiency metrics are used to assess how quickly and easily users can perform their tasks and goals with a product. They include measures such as clicks, scrolls, keystrokes, and mouse movements. These metrics can help you understand how users interact with a product and how intuitive and responsive it is. Efficiency metrics can also help you optimize the design and layout of a product and reduce the cognitive and physical effort required for users to access the information and functionality they need.

3 Satisfaction metrics

Satisfaction metrics are used to measure how users feel about their experience with a product. They include measures such as ratings, feedback, comments, and emotions. These metrics can help you capture the subjective and qualitative aspects of usability and accessibility, such as user preferences, expectations, attitudes, and emotions. Satisfaction metrics can also help you evaluate the overall appeal and value of a product and how it meets the needs and desires of different user groups.

4 Learnability metrics

Learnability metrics are used to determine how easy it is for users to learn how to use a product and remember how to use it in the future. They include measures such as time to learn, retention rate, and help requests. These metrics can help you evaluate the usability and accessibility of a product for novice and expert users, as well as users who may have cognitive or memory impairments. Learnability metrics can also help you improve the user education and support features of a product, such as instructions, tutorials, hints, and feedback.

5 Accessibility metrics

Accessibility metrics are used to measure how well a product conforms to the accessibility standards and guidelines, such as the Web Content Accessibility Guidelines (WCAG). They include measures such as compliance level, accessibility score, and accessibility issues. These metrics can help you verify and validate the technical and functional aspects of usability and accessibility, such as contrast, color, font, keyboard, screen reader, and captions. Accessibility metrics can also help you monitor and report the progress and quality of your accessibility testing efforts.
