Systems modeling language

It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems.

SysML offers several systems engineering specific improvements over UML, which has been developed as a software modeling language.

Likewise, with SysML one can use Parametric diagrams to precisely define performance and quantitative constraints like maximum acceleration, minimum curb weight, and total air conditioning capacity.

The SE DSIG, with support from INCOSE and the ISO AP 233 workgroup, developed the requirements for the modeling language, which were subsequently issued by the OMG parting in the UML for Systems Engineering Request for Proposal (UML for SE RFP; OMG document ad/03-03-41) in March 2003.

[7] Friedenthal served as Deputy Chair, and helped organize the original SysML Partners team.

[11] The OMG has been working on the next generation of SysML and issued a Request for Proposals (RFP) for version 2 on December 8, 2017, following its open standardization process.

As an OMG UML 2.0 profile, SysML models are designed to be exchanged using the XML Metadata Interchange (XMI) standard.
