Wand and Weber’s Decomposition Model in the Context of Business Process Modeling

Whereas the benefits of decomposing process models are obvious, the question what actually characterizes a “good” decomposition of a business process model has been given little attention to date. In addition, the process of decomposition itself is considered as being an “art” in literature. Our approach for achieving a “good” decomposition is Wand and Weber’s decomposition model for information systems. As a first step in our investigation we aim to explore in how far the decomposition model can be adapted for business process modeling at all. The potential this model might bear for evaluating decompositions of process models has been promoted in literature quite often, while a corresponding investigation is still missing. We address this gap by the following research. In the long term, we intend to establish guidelines for decomposing business process models in a structured way.
