Model-based systems engineering (MBSE)

Systems engineering is an independent engineering discipline that focuses on system properties, including functionality, structure, performance, safety, reliability, and security. Systems engineering is largely independent of the engineering disciplines used to implement these properties. Systems engineering is an interdisciplinary activity that focuses more on this integrated set of system properties than on the contributions of the individual engineering disciplines. It is an approach to developing complex and technologically diverse systems.

Systems engineering is normally thought of in a V-style process approach (see Figure 1.1), in which the "left side of the V" emphasizes the specification of the system properties (requirements, architecture, interfaces, and overall dependability), the "lower part of the V" has to do with the discipline-specific engineering and design work, and the "right side of the V"...
