This study examines task performance in computer-mediated collaborative environments from the perspective of interpersonal characteristics by considering the application of information systems (IS). Based on previous research, this study investigates the effects of relationship characteristics of members of an organization on their task performance. In addition, the study explores the ways in which IS can be applied effectively to improve the task performance in collaborative environments mediated by IS. From a socio-technical perspective, we defined community orientation, communicativeness, information sharing, and collaboration as relationship characteristics and performed regression analysis of their effects on perceived usefulness, user satisfaction, and indi-vidual performance through a survey of organizational members sharing the same IS. Based on the collected empirical data from the shipbuilding industry, the statistical results indicate that community orientation and communicativeness had significant effects on perceived usefulness, also indicate that information sharing and collaboration had substantial effects on user satisfaction. Both perceived usefulness and user satisfaction also had positive effects on task performance in the context of collaboration.
