Do system quality and information quality affect job performance? The mediation role of users’ perceptions

This study aims to analyze the influence of the system quality and information quality from the Correctional Database System (CDS) on the job performance of correctional Technical Support Officers (TSO) in Sumatra, either directly or through the mediating role of perceived ease of use and perceived usefulness. This study tested 118 correctional officers selected by the purposive sampling technique. A quantitative approach is used with Partial Least Square–Structural Equation Modeling analysis technique. It was found that the direct influence of the system and information quality on job performance is insignificant. Nonetheless, it shows that perceived ease of use and perceived usefulness fully mediate system quality and information quality on job performance. The findings demonstrate that perceived ease of use and perceived usefulness are important factors that motivate individual performance when supported by high-quality information systems. This study provides an overview of the use of a mandatory system for public organizations and the effects on user performance. It can be used as a basis for correctional institutions to strengthen and maintain a positive perception of CDS among their officers, such as through mentoring programs.
