Usability is the measure of a product's potential to
accomplish the goals of the user. In information technology, the term is often
used in relation to software applications and Web sites, but it can be used in
relation to any product that is employed to accomplish a task (for example, a
toaster, a car dashboard, or an alarm clock). Some factors used in determining
product usability are ease-of-use, visual consistency, and a clear, defined
process for evolution.
It is a method by which users of a product are asked to perform certain tasks in an effort to measure the product's ease-of-use, task time, and the user's perception of the experience.
