Abstract : Every company wants to improve the way it does business, or produce things more efficiently, and make greater profit. Therefore, business processes have become subject to evolutionary changes, which in turn increase the need for an efficient change support. In this sense, many researches were conducted to deal with business process adaptation to changes. The latter may result in the restructuring of the whole or a part of the process. Most of the proposed approaches focus on adaptation to changes in centralized processes. In sharp contrast to these works, our operation of change adaptation that we present in this paper, concerns decentralized orchestrations. Indeed, many recent approaches were proposed to decompose a composite web service into small partitions. Since the activities, the control and data flows are distributed over these partitions, it becomes difficult to specify the changes directly. Moreover, changing a derived partition may affect the way it interacts with others. In order to overcome these deficiencies, we propose a design-time methodology to support changes in decentralized business processes. We mainly demonstrate how to propagate the changes made on a centralized specification of composite web service to its resulting decentralized sub-processes.
