Abstract

We suggest eight reliable and valid measurement scales concerning the utilization of information systems based upon both computers and human communications for the support of production operations. Using these scales and a summarized super-scale, we empirically examine inter-industry and inter-class differences in the utilization level of information systems and its relationship with other operations management practices and competitive performance in order to evaluate the role of information systems for Japanese manufacturing companies. Correlation analyses demonstrate that production information systems depends on certain organizational settings and quality management practices, and that it strongly supports human resource management, just-in-time production, technology development, and manufacturing strategy.
