This paper presents the system concurrent engineering approach applied for the development of an autonomous star sensor. Traditional approaches focus solely on one aspect, that can be either the product, the development organization or the product operation. In those approaches the overall view of the inherent complexity in the development of a product, its life cycle processes and their performing organizations are not taken into consideration. Contrasting with those approaches, the system concurrent engineering performs, simultaneously, stakeholder analysis, requirements analysis, functional analysis and implementation architecture analysis for the product, its life cycle processes and their performing organization. From this, requirements and attributes are captured for the product and its life cycle processes organization, and the relationships between them are identified. Key conclusions are that the impact, traceability and hierarchy links promote the anticipation of the life cycle process requirements to the early stages of systems architecting. Late changes are avoided and development costs are significantly reduced, while satisfaction of stakeholders over the product life cycle is increased.
