Usability Metrics

Usability Metrics are quantitative measures used to evaluate the usability of a product or service. They provide objective data on aspects like efficiency (how quickly tasks can be completed), effectiveness (how successfully tasks can be completed), and satisfaction (how satisfied users are with the experience).

Usability Metrics can be collected through various methods, such as usability tests, surveys, and analytics. They can provide valuable benchmarks for evaluating the design and for measuring improvement over time.

Common Usability Metrics include success rate (the percentage of tasks completed successfully), error rate (the number of errors made), time-on-task (how long it takes to complete a task), and learnability (how quickly users can learn to use the product).
