Abstract:
The usability of an application often plays an important role in determining its success. Accordingly, organizations that develop software have realized the need to integrate usability engineering into their development lifecycles. Although usability practitioners have successfully applied usability engineering processes to increase the usability of user-interaction designs, the literature suggests that usability practitioners experience a number of difficulties that negatively impact their effectiveness. These difficulties include identifying and recording critical usability data, understandi

Abstract:
For over two decades user-centric methods and techniques have been proposed to assist the production of usable, useful, and desirable software products. Despite these approaches, usability problems are still identified in finished software products creating problems at systems acceptance, rework and impacting end user experience. Part of the reason for these continuing problems is that user-centric approaches are not part of the traditional software engineering process. The literature review shows that software engineering and human-computer interaction are largely different communities. The a

Human Computer Interaction (HCI) and Usability Engineering (UE) are areas of expertise that are still relatively new to computing and many HCI educationalists are still wrestling with methods of teaching in an effective way, a diverse and difficult subject.

This probably adds to the diversity of approaches adopted by HCI academics who attempt to fit in with the ethos of their hosting departments. In orde
