In recent years, the use of the System Concurrent Engineering methodology, developed by (LOUREIRO, 1999), is gaining visibility in the development of complex products, mainly in the automotive, aeronautical and space sectors. The main goals of this methodology are the integration of development organization with the processes of the product life cycle and the concurrent management of the requirements in the early phases of development. Thus, this methodology was used to develop an automobile interior configuration system and it was able to increase the viability, planning, development and organization during its life cycle. The system is classified as a complex product due to the large number of physical and functional parts and the large number of multidisciplinary areas responsible for its development. The application of this methodology increases controllability in the management of complex products development. For that end, this paper presents a brief description of the goals of this system and the stages of the applied development process depending on the methodology of (LOUREIRO, 1999).
