Abstract
This research aims to analyze the importance and relationships between the usability attributes for mobile application. The usability attributes were grouped into nine (9) factors such as efficiency, effectiveness, learnability, memorability, errors, satisfaction, cognitive workload, simplicity, and interruptibility. A total of 411 useable questionnaires form the basis of analysis. The results revealed that Errors (Mean = 3.82) was the most important usability attribute for mobile application and there was a significant correlation between satisfaction and errors, (r = .591, n = 411, p <.01). The numbers of navigational errors can potentially effects on user performance, user progress and user perception toward mobile applications. Many respondents also agreed that the higher satisfaction (Mean = 3.75), the more simple interface (Mean = 3.72), and the less cognitive workload attribute (Mean = 3.71) may enhance the level of usability of mobile application. Interestingly, satisfaction was found correlated with cognitive load (r = .553, n = 411, p <.01) and learnability was found correlated with memorability (r = .480, n = 411, p <.01). This study contributed in providing an insight into the importance and relationships between usability attributes which can be applied in usability measurement for mobile applications. � 2017 American Scientific Publishers All rights reserved.
