Cross-Functional Coordination: Collaborate with hardware/software/test engineers and naval stakeholders to align MBSE models with integration requirements, ensure onboard compatibility, and sustain traceability toward program goals and interoperability.
Configuration Management: Integrate model artifacts into CM workflows, capture lessons learned, and ensure compliance with MIL-STD-1521, INCOSE Guideposts, and program conventions.
