It is quite reasonable to presuppose that information systems provide various benefits to manufacturers. But we don’t have much evidence on the benefits especially in Japanese manufacturing. In this paper we investigated the hypotheses presented by Matsui and Sato   concerning the effects of information technologies and information systems upon manufacturing benefits with slightly different analytical approach and samples. We introduced more precise measure for implementation of information technologies and information systems, and divided the sample consisting of forty-six Japanese manufacturing companies into two sub-sample, world-class and random. The result of our analysis endorsed some of the propositions proved by Matsui and Sato , and provided new evidence to the hypotheses that utilization of statistical process control software improves product quality, implementation of computer-based production equipment control increases product-mix flexibility, and utilization of database for quality information and an increase in the percentage of external units electronically linked with the plant improve customer service. It also suggested additional hypotheses. Further, we discovered different relationships of information systems implementation with manufacturing benefits between world-class and randomly sampled companies.
