The level of complexity, sophistication and accuracy of space systems has continuously increased over the last years. Especially during the early design phases, a multidisciplinary team and a consistent approach are fundamental, along with appropriate tools and facilities, to reduce costs, to optimize the usage of time in terms of designing processes and increasing project robustness. The most popular approaches are usually sequential and centralized and largely applied because of their proven features. However, a more innovative approach consists in the “Concurrent Engineering” (CE), which is considered an up-and-coming method due to its design process performances and achieved results. A motivated and coordinated team of technical specialists, leveraging on different know-how and backgrounds, is the core of CE approach success.
