A Framework for Evaluating the Usability of Mobile Applications in Sudan

Abstract

The increasing usage of smartphones has resulted in mobile applications replacing or supplementing traditional web-based applications. Given the limitations of the form factor in smartphones, usability can be considered one of the important attributes that determine the success of a mobile application. Many of these applications suffer from usability issues. Usability concerns user experience, satisfaction, and perceptiveness.E-payment applications have barriers that make adoption of the application difficult for emergent users. If these barriers are crossed, many untapped users are waiting to use mobile payment applications. We conducted a small review of mobile usability models and found that usability is usually measured in terms of three attributes; effectiveness, efficiency, and satisfaction. Other attributes, such as memorability, tend to be overlooked in the usability models that are most prominent despite their likely impact on the success or failure of an application This research aims to review existing usability studies and subsequently propose a usability framework for the evaluation of the usability of Ocash apps, None of the attributes that it includes are new, but the existing prominent usability models ignore one or more of them The research uses the TAM model to evaluate the usability of the Ocash app. The framework serves as the basis for comprehensive usability evaluation consisting of guidelines, usability characteristics, and matrices.
