Employing an interpretative method, three conceptions of knowledge management have been identified among senior managers who are ‘immersed’ in ERP. Managers understand knowledge management as: (1) change management for implementing and maintaining an ERP system; (2) corporate information management based on and beyond an ERP system; (3) the integration of change management and corporate information management by means of an ERP system. The results may inform further research, such as case studies, higher education and practice.
