Journal of Information & Systems Management Rana Yousef, Mohammed Odeh 3 4 2013 http://www.dline.info/jism/fulltext/v3n4/1.pdf As the number of applications that depend on the architectural design of an enterprise increases, modelling business process architecture has become essential. In this paper we adapt the concept of reverse-engineering to derive business process architecture from business process models. Specifically, we present a method to derive a Riva-based business process architecture from a given set of business process models. The presented method is demonstrated using a real case study, the Cancer Care and Registration in Jordan.
