Which term is defined as the formalized design and application of modeling to support system requirements, design, and analysis starting in the concept stage and continuing throughout development and later life cycle stages?

Which term is defined as the formalized design and application of modeling to support system requirements, design, and analysis starting in the concept stage and continuing throughout development and later life cycle stages?

• A. Agile System Engineering
• B. Model-Based Systems Engineering
• C. Traceability
• D. Architecture Description Framework

Answer: (B)

The idea being tested is using models as the central, formalized means to describe and analyze the system from early concept through development and into life-cycle stages. This approach treats modeling as the primary vehicle for capturing requirements, guiding design, and performing analyses, so the system can be understood, tested, and evolved based on a single, integrated representation. It enables early trade studies, simulations, and traceability across the entire life cycle, helping ensure that what is built aligns with what is needed and can be maintained over time. This is why it fits best: it emphasizes a model-centric way to manage requirements, design, and analysis throughout development and operations, rather than relying primarily on documents or separate architectural structures. Other terms describe related ideas—agile methods applied to systems engineering, the ability to trace requirements to design and tests, or a framework for describing architectures—but they do not capture the formalized, ongoing use of modeling as the main tool across the whole life cycle.
