Usability is a measure of how easy it is for people to use a product, service, or system. It is concerned with the user’s experience and their ability to accomplish their goals in an efficient, effective, and satisfying way. Usability is an important consideration in the design of products and services, as it can affect their success and adoption. Factors that contribute to usability include the design of the user interface, the clarity and organization of information, and the effectiveness of navigation and controls. Usability can be evaluated through a variety of methods, including usability testing, in which users are asked to use a product or service and provide feedback on their experience.
