MBSE
Methodology that focuses on creating domain models as the primary means of information exchange between engineers, rather than on document-based information exchange.
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. (INCOSE 2007)

Model-based systems engineering (MBSE) represents a paradigm shift in systems engineering, replacing traditional document-centric approaches with a methodology that uses structured domain models as the primary means of information exchange and system representation throughout the engineering lifecycle.
Unlike document-based approaches where system specifications are scattered across numerous text documents, spreadsheets, and diagrams that can become inconsistent over time, MBSE centralizes information in interconnected models that automatically maintain relationships between system elements. These models serve as the authoritative source of truth for system design, enabling automated verification of requirements, real-time impact analysis of proposed changes, and generation of consistent documentation from a single source. This approach significantly reduces errors from manual synchronization, improves traceability between requirements and implementation, and facilitates earlier detection of design flaws through simulation and analysis.
The MBSE approach has been widely adopted across industries dealing with complex systems development, including aerospace, defense, rail, automotive, and manufacturing. By enabling consistent system representation across disciplines and development phases, MBSE helps organizations manage complexity, reduce development risks, improve quality, and enhance collaboration among multidisciplinary teams.
The International Council on Systems Engineering (INCOSE) defines MBSE as 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.
