Many companies have become aware of the potential of Model-Based Systems Engineering (MBSE), such as increased quality and shorter development times, and have begun to look at this approach for themselves and evaluate the potential of implementing it in their own organizations. As MBSE is defined by the International Council on Systems Engineering (INCOSE) as the formalized application of modeling to support various system activities, such as system requirements, design, analysis, verification, and validation from the concept phase to late lifecycle phases, this adoption and implementation differs among companies. In a joint project between Siemens PLM Software and Fraunhofer IPK, a maturity model was developed that assesses a company's ability to successfully operate MBSE.
