This paper presents a system concurrent engineering approach for the development of an aeronautical navigation system. Traditional approaches focus on the product, the development organization and the product’s concepts of operation (CONOPS). In those approaches, the overall view of the inherent complexity in the development of a product, its life cycle processes and their performing organization are not taken into consideration. The system concurrent engineering performs stakeholder analysis, requirements analysis, functional analysis and implementation architecture analysis, simultaneously, for the product, its life cycle processes and their performing organization. From the analysis, requirements and attributes are captured for the product and its life cycle processes organization and the relationship between them is identified. We have concluded that, impact, traceability and hierarchy links promote the anticipation of life cycle process requirements to the early stages of systems architecting. Late changes are avoided; development costs are dramatically reduced; while satisfaction of stakeholders over product life cycle is increased. In this paper the advantages of the concurrent engineering approach are evidenced along the development activities of an Aeronautical Navigation System.
