Abstract: The change process, investment, training, and tools needed to implement a model-based systems engineering (MBSE) approach across the engineering enterprise are substantial. How is the change from a document-based systems engineering approach (DBSE) to a model-based systems engineering approach (MBSE) justified? The primary conclusion from a literature review is that there is a significant advantage to project performance by applying an MBSE approach. An MBSE approach made the engineering processes on a complex system development effort more efficient by improving requirements completeness, consistency, and communication. These were seen in engineering processes involved in requirements management, concept exploration, design reuse, test and qualification, Verification and Validation, and margins analyses. An MBSE approach was most effective at improving defect prevention strategies. The approach was found to enhance the capability to find defects early in the system development life cycle (SDLC), when they could be fixed with less impact and prevented rework in later phases, thus mitigating risks to cost, schedule, and mission.
