According as information systems become more important for business activities, they should be evaluated adequately their effectiveness and suitability. However, it is difficult to evaluate the latest information systems that provide the work support functions, such as groupware, internet and so on, as to compare with the legacy information systems that provide the automation functions. In this paper we propose a method to evaluate the suitability of work support functions for business information systems. The method provides the ability to evaluate quantitatively the functional suitability between the business process and the business resources, such as information systems and workers, using the functional process model and fuzzy relation. The method consists of three schemes: (l) derivation scheme of the functional process model, (2) evaluation scheme of the functional suitability, and (3) analysis scheme of the functional suitability on the type of information processing, the level of information processing, and the type of human-machine interaction. Furthermore, we will show the validity and the usefulness of the method in a case study.
