The objective of this study was to find the factors that influence information quality of the system by utilizing participative decision-making theory and communication competence framework. Based on this framework, this study tested the effects of certain users’ characteristics on information quality. Results indicated that there was a positive correlation between user participation and information quality. Moderated regression analyses showed that users’ job experiences negatively moderated the relationship, while a component of communication competence--modeling cognition--positively moderated it. The findings of this study have implications for selecting users to participate in information systems projects.
