👌Usability

NEW

A quality attribute describing how easily specified users achieve goals effectively, efficiently, and satisfactorily in a given context.

DESCRIPTION

Usability measures ease of learning and use for target users in defined contexts. ISO 9241-11 frames effectiveness, efficiency, and satisfaction as core outcomes. Methods include heuristic evaluations, usability testing, and cognitive walkthroughs. Good usability reduces errors, speeds task completion, and improves adoption. It complements accessibility and overall user experience. In data products, usability clarifies metrics, filters, and workflows for insight discovery.
