Perceived Usability of Software Systems: A Framework-Driven Study
Journal of Logistics Informatics and Service Science · 2022
The main objective of perceived usability studies is to develop better quality software that is both efficient and effective.Retrospective usability studies in the literature are rich in data that can be used by systems developers to achieve that purpose.However, some developers still fail to make use of users' past user experiences, and as a result some systems continue to include persistent flaws following updates.To address this problem, a conceptual framework of evaluation was developed from the usability evaluation literature.This research proposes a Perceived Usability Evaluation Framework to be consulted by evaluators during maintenance and system updates.To validate this framework, the researchers used evidence empirically collected from the Public Authority for Applied Education and Training (PAAET) online registration system.Results indicate that the framework provides a promising structure which can be followed by researchers, practitioners and systems developers when synthesizing patterns of dissatisfaction from previous system usability evaluations, and these syntheses can in turn can guide future system updates.
