What are the best metrics for UX Performance and Quality?

Published 10 days ago

The plan titled "Measuring UX Laws and Audit" focuses on evaluating and enhancing User Experience (UX) performance and quality. It incorporates a set of metrics designed to assess key areas like user satisfaction, task success, and retention rates. By leveraging metrics such as the User Satisfaction Score and Task Success Rate, businesses can pinpoint areas for improvement, ensuring that users have a seamless and intuitive experience.

For instance, improving the User Satisfaction Score involves iterating on design based on regular feedback, while a high Task Success Rate can be achieved through optimizing task flows and instruction clarity. Understanding these metrics is essential for refining the user interface and, ultimately, increasing user engagement and retention.
