Business Process Management (BPM) and supporting BPM-systems are increasingly implemented within organizations and supply chains. However a common accepted definition of the BPM-concept is omitted and the same is true for the competencies (knowledge, skills and attitudes) that project members need during a BPM-implementation. In this paper we present the results of a survey among Dutch consultants, developers and end-users of BPM-systems. The survey is designed to investigate whether there is a shared view among different disciplines with regard to the definition of BPM and the relevant competencies for BPM implementation. After presentation and interpretation of the results of this survey, we propose an international study to explore if BPM definitions and its relevant competencies differ across regions and cultures.
