Usability Evaluation of Microsoft Teams Applications for Higher Education

Interface design evaluation is part of human-computer interaction. The focus of this research is to carry out a heuristic evaluation on the interface design of an online learning application, namely Microsoft Teams, to determine the extent to which the application meets the usability concept of interface design. Microsoft Teams is an application that is the choice of many universities in Indonesia to provide online learning. Microsoft Teams can be accessed by students, course lecturers and Digital Learning Subdivision units (the team that manages e-leaning). This research uses a heuristic evaluation method which includes several usability principles such as Jacob Nielsen's ten principles of usability. To facilitate evaluation of the user interface, this research combines heuristic checklists and severity ratings. Severity ratings are associated with problems that arise and have varying levels of seriousness. There are 5 (five) value categories in severity ratings, starting from 0 (cosmetic), which means there is no problem, up to 4 (critical), which means it is very important to fix the problem and is a top priority. This research involving 7 evaluators consisting of IT admins and lecturers who will carry out assessments by filling in a heuristic checklist. The stages of research activities carried out include 6 stages consisting of: preparation, problem formulation, method selection, evaluation using the hueristic evaluation method, discussion of results and preparation of recommendations for improvement. The results obtained were that there were 109 problems in ten heuristic principles, most of which were in the minor category and needed to be corrected in the principles of system status visibility, user control and freedom principles, error prevention principles, and assistance and documentation principles in Microsoft Teams.
