MBSE FAQ: What is Model-Based Systems Engineering (MBSE)?

Model-Based Systems Engineering (MBSE) is a Systems Engineering paradigm that emphasizes the application of rigorous visual 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, validation and verification; functional analysis and allocations; performance analysis and trade studies; and system architecture specification.

Usage Note: The term Model-Based Systems Engineering (MBSE) is especially popular among Systems Engineers who advocate the use of the Systems Modeling Language (SysML) as a standard visual architecture modeling language for Systems Engineering applications, and who want to distinguish their approach from Model-Driven Development and its variants, which tend to be software centric.
