MITRE works with sponsors to research, design, and deploy complex systems of systems for the 21st century. In today’s heavily networked world, many systems must function as part of larger systems of systems (SoS) with complex integration requirements. MITRE’s sponsors recognize the criticality of effective end-to-end performance of SoS that support their operations, and they continually invest in new and modernized systems that must integrate into their SoS. When integrating new systems into an SoS, sponsors must ensure that users can continue to support current operations. MITRE’s SoS approach addresses these challenges by providing a deliberate, data-driven methodology for verifying that an SoS meets user requirements and that new systems are integrated with minimal disturbance to existing capabilities
