MBSE FAQ: Who created MBSE and how did it get its name?

Model-based specification and simulation techniques have been associated with Systems Engineering since its inception as an interdisciplinary field of engineering, which can be traced to work at Bell Telephone Laboratories and US Department of Defense (DoD) during the 1940s

The term Model-Based Systems Engineering became popular during the standardization of the Systems Modeling Language (SysML), which was created by the SysML Partners consortium during 2003-2005. The SysML Partners published the SysML 1.0 alpha open source specification in November 2005, and the Object Management Group adopted a variation as OMG SysML 1.0 in 2006. The standardization of SysML resulted in widespread tool support for the new visual language standard and associated MBSE processes.
