Model-Based Systems Engineering (MBSE; a.k.a. Model-Based Systems Development [MBSD]): a Systems Engineering process paradigm that emphasizes the application of rigorous architecture modeling principles and best practices to Systems Engineering activities throughout the System Development Life Cycle (SDLC). These Systems Engineering activities include, but are not limited to, requirements analysis, functional analysis, performance analysis, system design, trade studies, system architecture specification, and system Verification & Validation (V&V).
According to the INCOSE SEBoK (Systems Engineering Book of Knowledge), MBSE can be considered a "subset of digital engineering". To learn more about MBSE's relationship with Digital Engineering technologies, check out the relevant FAQs below.
