Abstract: Human Resource Information Systems (HRIS) are increasingly being implemented by universities in order to streamline processes and improve quality. Usability plays a very important role in improving the effectiveness of these systems. This study reports on an in-depth usability study of online human resource information system at Fiji National University. The study was carried out using sixty users who examined the system for usefulness, satisfaction and ease of use. The data gathered was subjected to reliability analysis followed by a comprehensive evaluation based on the specified usability criteria. The results portrayed that the usability problems were few and minor thus recommendations were derived to further improve the HRIS. Findings of this research can be applied to develop a set of guidelines to support the future design of online HRIS.
