Timeliness, steadiness, behaviourness and effortlessness: an efficiency evaluation model for measuring mobile applications usage

Both the theory and practice of measuring the efficiency of mobile applications usage have been hampered by the absence of a thorough mathematically based model as a method for evaluation. This research effort has been in a position to derive a preliminary mathematically based specification and measurement scheme specifically for assessing the mobile applications usage from the perspective of efficiency measures. The ultimate value for developing a mathematical oriented approach is to provide a systematic and quantitative method for conducting mobile applications usage efficiency evaluation research. As a result, a total number of 39 metrics and 10 attributes and 4 criterions were identified having associated towards measuring the efficiency of mobile applications usage. The applicability of the model was also tested on two experimental systems: Training Evaluation System (PELAKAD) group where participants manipulated the cadet training tasksand Clinical Information System (CAPSULE) group where participants manipulated the clinical delivery tasks). Analysis of the efficiency on both types of systems was assessed in terms of timeliness, steadiness, behaviourness, and effortlessness. As a result, it was concluded that the model developed and proposed in this study provides a common basis for comparison between systems as well as helping in selecting suitable product based on their needs and requirements. By producing a quantifiable measurement, the overall efficiency of mobile applications usage thus can be assessed
