Abstract

In this study, the usability modeling and usability test comparison of the mobile applications of different users and 2 phone providers were made. This modeling and comparison test was carried out with the CogTool tool for usability testing. In the study, 3 different levels of users were expected to perform a given task on the mobile applications of two different telephone line providers. As a duty, balance top-ups are given to the phone lines in the mobile applications of these providers. Looking at the results, the usability test with the CogTool tool took 14.2 seconds for one provider and 7.3 seconds for the other provider. Despite being given the same task, the time has nearly doubled because a provider is missing a step. At the same time, the completion times of 3 different levels of users are compared and given in tables
