An initial theoretical usability evaluation model for assessing defence mobile e-based application system

This study is aimed for developing a framework of usability metrics specifically for assessing usability in mobile applications. This study is design to achieve fifteen major attributes: accurateness; attractiveness; behaviorness; cognitive load; effectiveness; efficiency; effortlessness; errors; learnability; memorability; operability; satisfaction; steadiness; timeliness; and understandability. As a results, a usability framework based on the sequence of Goal, Attributes and Metrics (GAM) is developed in which outlined metrics is used for measuring the different attributes. This framework can be used for constructing usability model for assessing usability in mobile applications.
