Reflecting modeling languages regarding Wand and Weber's decomposition model

Abstract

The benefits of decomposing process models are widely recognized in literature. Nevertheless, the question of what actually constitutes a “good” decomposition of a business process model has not yet been dealt with in detail. Our starting point for obtaining a “good” decomposition is Wand and Weber's decomposition model for information systems which is specified for business process modeling. In the investigation at hand, we aim to explore in how far modeling languages support the user in fulfilling the decomposition conditions according to Wand and Weber. An important result of the investigation is that all investigated business process modeling languages (BPMN, eEPC, UML AD) can meet most of the requirements.
