We clarified, in our previous studies, some features of maintenance activities of the campus information system of a polytechnic college from the following three viewpoints: activities through time, differences in workload, and work priorities. Based on those results, this paper show that maintenance activities can bear the responsibility of an active role in the information system life cycle management. Particularly, the life cycle management of our target information systems in higher educational and research institutes closely involves users through its every phases. For the reason we focus on the developed or changed data of maintenance activities in the relation with users, and analyze the features of such maintenance activities. Finally, we propose a new focus on system life cycle management that co-creates with users.
