SysPEM: Proposing a coherent model for systems engineering processes

In a highly competitive environment, companies must guarantee the quality of their products through the quality of the manufacturing process. These processes are the keystone of Systems engineering as a heterogeneous field that consolidates the different aspects of manufacturing a product. This means that the processes participating in systems engineering must be optimized and coordinated. The work in this paper proposes a coherent systems engineering processes model which is validated through some predefined criteria, systems engineering standard EIA 632, and a case study of modeling a simple process.
