Model-Based Systems Engineering (MBSE)

Based on an engineering methodology, modeling language, graphical-based modeling tools

Formalized application of modeling to support system requirements, design, analysis, verification and validation activities

Begins in the conceptual design phase and continues

 throughout development and later life cycle phases

Model elements contain the design and development information

Includes discipline-specific engineering models and simulation

Provides a single source of information

Information can be extracted into supporting documentation as needed
