The Expert Community "System and Costs" brings together two sub-communities
- The "System Engineering" COMmunity of ExperTs (COMET SYS) encompassing the system engineering themes and the space system trades that define, design, implement and validate a complex spacel system in response to the requirements of an end customer.
- The "Cost Engineering" COMmunity of ExperTs (COMET COST) dealing with general cost estimation methodologies and more specifically for their applications.
Cost Engineering is regarded as inherently linked to System Engineering; similar to the mass budget and power budget, a cost budget facilitates trade-offs at various design levels by providing awareness of cost associated with technical decisions. Cost Engineering forms a major metric for the performance of a space mission.
