Abstract
This study investigates the extent to which the usability attributes, namely, effectiveness, efficiency; learnability and memorability, satisfaction, errors, and cognitive load of PSAU mobile application exist from students’ point of view who were enrolling at the academic year 2019-2020 in College of Business Administration (CBA) at Prince Sattam Bin Abdulaziz University. The study employs the People at the Center of Mobile Application Development (PAMCAD) usability model to determine the extent to which the usability attributes are available of PSAU mobile application. A survey-based methodology is used to collect data from a random sample size of 137 enrolled students in the College of Business Administration (CBA) at Prince Sattam bin Abdulaziz University. The results demonstrate the state of usability attributes of PSAU mobile application is acceptable; the highest mean was 3.3 for the cognitive load dimension, after that, the learnability and memorability dimensions with mean 3.0. The lowest mean is 2.4 for the Efficiency dimension. The overall mean for usability is 2.8 which reflect the level of usability for the PSAU mobile application. The results of this study should be useful to IT deanships and related policymakers at the university level with empirical evidence about the issues and problems that faced users of mobile applications in higher educational institutions in KSA; and helping in developing high-quality mobile application.
Highlights
Mobile application is software that designs to work on mobile computing platform
As mention the previous sections the PACMAD model has been employed in this study which depends on six attributes for determine the usability of mobile application
The main goal of the current study is to examine the extent to which the usability attributes, namely; effectiveness, efficiency, learnability and memorability, satisfaction, errors and cognitive load of PSAU mobile application exist among students who were enrolled in College of Business Administration (CBA) at Prince Sattam Bin Abdullaziz University for the academic year 2019-2020
Summary
Mobile application (app) is software that designs to work on mobile computing platform. The usability is the major issue that may affect the usage of the mobile applications. ISO 9241-11 defines usability as ‘‘the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use’’ (Moumane et al, 2016; Sagar and Saha, 2017; Seffah et al, 2006). Evaluating the usability of mobile applications is very important, due to proliferation the usage of mobile devices, determining the level of acceptance by its users and discovering the major issues that faced the users of that application and to gain feedback of interface design. Many methods are suggested for evaluating the usability for mobile applications (Moumane et al, 2016; Kortum and Sorber, 2015; Hashim and Ahmad, 2016; Kumar and Goundar, 2019; Nielsen and Mack, 1994; Nielsen and Molich, 1990; Harrison et al, 2013; Parsazadeh et al, 2018; Az-zahra et al, 2019)
