Usability Requirements
Translate User Experience Objectives Into Technical Requirements
Usability requirements establish expectations for how effectively and efficiently intended users should interact with a system, application, product, website, or service. Lamtas converts user experience objectives into structured requirements that can guide design and evaluation.
Requirements can address ease of learning, navigation, accessibility, task completion, interface consistency, error prevention, user guidance, terminology, feedback, and other characteristics that influence practical usability.
