In user-centered design (UCD), tasks (also known as use cases or scenarios) represent a sketched-out problem statement that is implemented during a usability test. It is important that the tasks have measurable and quantifiable objectives and that these objectives are based on the high-priority goals of the business.

Tasks should represent common activities that users might want to engage in that have significant value to the business.
