Managing IT-Expertise: Towards an Organizational Memory System as a Tool for IT-based Process Improvements Frank Habermann, August-Wilhelm Scheer Institute for Information Systems, University of the Saarland, Germany This paper analyzes major problems concerning IT management and examines how an organizational memory system (OMS) may help to overcome them. Emphasis is placed on the organizational impacts of IT, particularly its effects on business processes. This domain was selected because (1) the problems of managing IT and the urge to continuously improve business practices are both very important and closely connected aspects, (2) despite the many excellent approaches to the field, some major questions call for further research, (3) it consists of a bounded knowledge area that can be managed by means of an OMS. Thus, our work discusses theoretical as well as practical questions of expertise management for the purpose of IT-based process improvements and aims at providing instruments which will help people who are concerned with managing IT. A main characteristic of the presented OMS is a novel model-based approach to process documentation. Firstly, since so-called “operators” are syste- matically derived from various levels of process models the documentation will be consistent. Secondly, the use of textual operators makes describing processes easy. Thus, the use of the documentation tool will not require specific qualifications and can therefore be applied by IT-expertise owners at any enterprise level.
