Abstract
When designing an information system generally, the strategic approach based on objective analysis and logical thinking is thought of as important. However, we discovered in our evaluation of practice of PBL which was performed in five companies that the realizable computerization is not related closely to the logical thinking nor strategic approach but to the specialized work style, original culture and the scenario for the future planned by a president. This paper reports the practice process of PBL and considers the introductory model of the information system based on the observed contents.
