A Survey of Comparative Business Process Modeling Approaches

There has been a huge influx of business process modeling languages as business process management (BPM) and process-aware information systems continue to expand into various business domains. The origins of process modeling languages are quite diverse, although two dominant approaches can be observed; one based on graphical models, and the other based on rule specifications. However, at this time, there is no report in literature that specifically targets a comparative analysis of these two approaches, on aspects such as the relative areas of application, power of expression, and limitations. In this paper we have attempted to address this question. We will present both a survey of the two approaches as well as a critical and comparative analysis.
