Today high competitive market needs fast, effective, high responsiveness, online interactive, 24-hours-7-days-a-week availability and easy to follow up orders processing. Supply chain management information systems are the information systems between companies that employ information and communication technology to arrange information inside & among the participators of a supply chain such as clients, sellers, providers, and distributors. Companies frequently use a portfolio of supply chain management information systems, which characteristically contain legacy systems linked by electronic data interchange, packaged applications employing Web-based exchange of information or ideas, or some other blend of information connection technology. Thus, the goal of this study is to identify the system’s main elements, analyze the system’s operational issues, identify the inputs and outputs for each element of the system, define the interfaces between the related activities in the system, design relation data model and develop a prototype SCMIS. It is hoped that the model that has been developed is able to integrate and enrich theories of competitive strategy, supply chain management.
