The demand for quality software system is increasing day by day, but most software system fails to fulfill the expectations of its users due to lack of usability. Since usability is recognized as an important quality factor of software system, so to develop quality system it is necessary to have single and precise definition of usability. Researchers have not developed yet any model that recisely describes usability definition and all its attributes thattakes into account the varying aspects of usability. This paper provides a roadmap by analytical review of usability definitions and their decomposition in various attributes. The aim of review is that it may help to software systems’ designers, developers and users to select the usable system on the basis of various parameters defined in the paper.
