To cope with market dynamic and shortened time to market, industrial companies need toimplement an effective management of their design processes (DPs) and product information.Unfortunately, Product Lifecycle Management (PLM) systems which are dedicated to support designactivities are not efficient as it might be expected. Indeed, DPs are changing, emergent and nondeterministic, due to the business environment under which they are carried out. The aim of this workis to propose an alternative approach for flexible process support within PLM systems to facilitate thecoupling with the environment reality. The purpose of a support system is to accelerate the process byautomating the notification and dispatching of information and activities between actors. It also allowsto keep track of transactions and decisions made and to increase processes standardization. Our goal isto propose a solution which allows process change at run-time without having to redefine and restartthe whole of process activities. To achieve this, we proposed an approach based on service-orientedarchitectures (SOA). These architectures allow defining modular applications, using loosly coopledservices. They are mainly exploited for software systems and Web development. Our goal is to declinesuch architectures at the business level of a company in order to perform flexible DPs deploymentbased on services reuse and composition. We propose an identification approach for business levelservices (product design services) and functional PLM services. These services are organized in twocatalogs of business and functional services. Our approach is based on Model Driven Approach withthree levels which propose alignment mechanisms between business, functional and technical levels.These alignment mechanisms between levels allow integrating change and automating design processdeployment.
