Abstract

Usability is an important quality attribute for information technology (IT) applications. However, integrating usability design and evaluation as an integral part of the development processes in information technology development organizations is still a challenge. This chapter gives an overview on the usability cost-benefit analysis models and provides some example cases of the importance of usability. These models and cases can be used by usability professionals to motivate the organizational management to provide resources for usability work and to integrate usability work as part of the development process. The target audience for this chapter are professionals and researchers working in the field of IT, managers in IT development organizations, as well as managers in organizations acquiring and using IT.
