How a close association of System Design, Technical Management and Acquisition & Supply processes can improve system design engineering ?

Industries have to design and produce performing and reliable systems. Nevertheless, designers suffer from the diversity of methods, which are not really adequate to their needs. Authors highlight the interactions between processes involved into the global design process, and focus on the product and project design processes, often treated either independently or sequentially. They study the organisation of the exchanges between these two processes and propose a methodology with regard to the standards of System Engineering and the recommendations of Model Driven Engineering (MDE), in the context of what is called the 'co-design' paradigm. Finally, this study is extended to the design of network of partners process also
