Abstract
The Department of Defense (DOD) wants to implement Model-Based System Engineering (MBSE) to accelerate and improve the acquisition process of increasingly complex systems. However, the department has not provided the necessary guidance on how to fully implement MBSE into our systems. This provided the following research opportunity: select a common DOD process, create an MBSE methodology, generate a model in accordance with that developed method, record the cost of modeling, and interview the model recipients to characterize their opinions on the investment. The research created a twelve-step methodology for application towards the gap analysis and characterization phase of a Capability-Based Assessment (CBA) for the Joint Forward Edge Command and Control (C2) CBA report. The research identified thirteen data groups: The model took 149.6 creation hours, with 69.8 hours devoted toward data structure and ontology, and 79.75 hours modeling the specific instance. The total cost for the software tool, training, and labor equated to just under $20,000. When interviewed, stakeholders viewed the model as being beneficial through traceability, ease of iteration, and reuse, far outweighing the time and financial cost spent building the model. Additional opportunities for future research include altering the analysis technique and expanding the model’s scope.
