Model-Based Systems Engineering (MBSE)
Definitions
“Model-based systems engineering (MBSE) is a
systems engineering methodology that focuses on
creating and exploiting domain modelsas the primary means of information exchange
between engineers, rather than on
document-based information
exchange.”

Outcomes
Transformations
Signals Networks
1. Process: Digital models become the
authoritative information source driving all
downstream implementation steps
2. Transformation into subsequent forms is
significantly automated to create correct-
by-construction outcomes
3. A core MBE tenet: data created once is
reused to the greatest extent possible by
all downstream consumers - Significant Automation -
