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.

Why it matters

MBSE provides the system model that bridges mechanical (PLM) and software (ALM) design, enabling traceability from customer requirement to shipped product.
