MBSE (Model-Based Systems Engineering)
Model-Based Systems Engineering (MBSE) is a systems engineering methodology that uses formal, connected models—rather than documents—to specify, design, analyze, verify, and validate complex systems throughout the development lifecycle. It provides the systems-level framework that defines what must be simulated and how simulation evidence connects to requirements.
In context
Lockheed Martin applies MBSE on F-35 derivative programs using SysML in Cameo Systems Modeler — requirements, architecture blocks, interface definitions, and verification events are all connected in one model rather than scattered across Word documents and spreadsheets. When a structural requirement changes, the MBSE model immediately identifies which SysML blocks and linked simulation analyses are affected, driving a targeted re-verification campaign rather than a full program rescan.
Why it matters
MBSE provides the system model that bridges mechanical (PLM) and software (ALM) design, enabling traceability from customer requirement to shipped product.
