Abstract

Recently there have been some discussion about possible revolutions in business process management. It is evident, that business process management up to now misses a solid scientific foundation. This has led to misinterpretations during implementation of business process management in organizations on one side, and uncoordinated research directions and results on the other side. It can be shown, that actual concepts, such as BPMN 2.0 or scientific community driven concepts such as Petri-nets do not fit business and organizational needs. We discuss one possible step forward to come up with a solid scientific definition of business process management, id est process calculi such as CCS and π-calculus. Based on these algebras, we can define and study business processes on a formal basis. Further on, we demonstrate that such calculi are not only theoretical concepts, but can be used for daily business process modeling and enactment in the from of the subject-oriented business process management (S-BPM) methodology.
