ABSTRACT
To improve business processes, we have to understand the current processes in detail, but business analysis is not an easy task and takes considerable costs. We suppose that a business support system is constructed based on a business model. Therefore, in our research, we aim to construct a business model from data flows in a business support system. In this paper, we report a procedure to construct an IDEF0 diagram by analyzing data items in Web pages which are the interface of a business support system, and a prototype tool to generate the diagram automatically.
