Usability Evaluation of a Locally Developed Software Using Iso Metrics

Abstract

In the information technology era, there is a rapid noticeable increase in software application demand, especially in the last decade. Software development firms are established to meet this demand. Due to the common lack of usability feedback in locally developed systems in Libya, a usability evaluation framework is needed. In this research, a usability evaluation of locally developed software was performed and conducted on Bank Current Accounts Function users (the account handlers within the bank) on Almezan Banking Software System, in Libya. The research aims to measure the usability of Almezan software from the user point of view, using the international tool IsoMetrics (ISO) standard. The study methodology steps included preparing and describing a questionnaire, then defining the type of the sample of the population and the place of distribution of the questionnaire. The results of the data analysis show that the principles of Controllability and Suitability for learning from a user point of view, have received the best-rated feedback of the system. Unlike in Error tolerance and Suitability for individualization, which got lower-rated feedback according to users’ expectations. A comparison has been made between the software under this study’s results and another source of study. The results of the comparison have revealed that the Almezan Software got higher usability of users’ expectations in Suitability for the task, Self-descriptiveness, Controllability, and Conformity with user expectations, while their mean values were significantly different. Furthermore, Error tolerance, Suitability for individualization, and Suitability for learning results were similar, while their mean values showed that they were not particularly different.
