Model Based Systems Engineering (MBSE) uses modeling languages and tools to provide a single source of truth for complex systems. It enables high confidence in early system validation through industry-proven simulation technologies and best practices. MBSE provides integration with solutions for quality planning and verification & validation, facilitating test strategy management.

MODEL BASED SYSTEMS ENGINEERING
“Model-based systems engineering (MBSE) is the formalized application of modeling to
support system requirements, design, analysis, verification and validation activities
beginning in the conceptual design phase and continuing throughout development and
later life cycle phases.”
