as well as other traditional terms such as user friendliness, usefulness, ease of use, have in common that they are vague and fuzzy terms They give the impression of just one single dimension However, users have different needs and requirements and perform different tasks with an application An application which is usable by one user may be tedious to use by another user In addition usability is a too narrow concept which does not take into account cost/benefit issues Hence, the term 'quality of use' is prefered to usability

Refers to the ease of learning and using a user interface
The extent to which an item is capable of being used, or is convenient and practical in use

The ease with which a user can operate, prepare inputs for, and interpret outputs of a system or component
The combination of design, content, navigation, and technical issues which determine how useful a Website is for a given purpose (information retrieval, sales, recreation, etc ) The concept arose because of unusable indulgence -- so most adherents are advocates of restraint, some almost to the point of minimalism Two usability experts frequently cited by Scribble & Count are Jakob Nielsen and Jared Spool; two periodicals advocating usability issues are Alertbox, and Contentious; all are cited in the Bibliography (See also, the S&C essay on "Assertive Users" in the Archive )
Refers to design features that make a product user friendly For instance, Web sites with usability problems could be hard to navigate, difficult for disabled people to use, or have unclear instructions for use
