This study developed a University web-based election system and determined the factors that could predict its usability. Specifically, it aimed to understand the role of trust in web-based election system usability. Three steps of hierarchical regression analysis on the 400 data samples showed that trust towards the system was a consistent predictor of web-based election system usability. It was also shown that technical aspects (i.e., reliability, aesthetics, and user-friendliness) of web-based election design factors, though significant predictors, did not have much impact on the usability of the software. Trust had the highest beta coefficient among the three factors indicating that it contributed most in the usability of a web-based election system. Further, the predictors could capture 90% of the usability design of the system. Thus, the null hypothesis stating that web-design related factors and trust towards the software, singly or in combination, do not predict web-based election system usability is partially rejected. Recommendations were also presented.
