== History ==
The orgins of the SysML initiative can be traced to a strategic decision by the International Council on Systems Engineering’s
SysML grew out of efforts by the [[Object Management Group]] (OMG) Systems Engineering Domain Special Interest Group (SE DSIG), a group jointly chartered by OMG and the [[INCOSE|International Council On Systems Engineering]] (INCOSE) to develop an extension of the UML suitable for use by systems engineers. The SE DSIG issued a ''Request For Information'' on "UML for Systems Engineering" in February of 2002.<ref name="rfi">{{cite web|author=OMG SE DSIG|title=UML® for Systems Engineering RFI|url=http://www.omg.org/technology/documents/UML_for_Systems_Engineering_RFI.htm|accessdate=2006-06-29}}</ref> Thirteen different organizations, including tool vendors, universities, and professional societies, responded to the request for information. <ref name="rfi"/> In March of 2003 the SE DSIG issued a ''Request For Proposals'' which prescribed requirements for a "UML for Systems Engineering".<ref name="rfp">{{cite web|author=OMG SE DSIG|title=UML<sup>TM</sup> for Systems Engineering RFP|url=http://syseng.omg.org/UML_for_SE_RFP.htm|accessdate=2006-06-29}}</ref>
(INCOSE) Model Driven Systems Design workgroup in January 2001 to customize the Unified Modeling Language
(UML) for systems engineering applications. This resulted in a collaborative effort between INCOSE and the Object
Management Group (OMG), which maintains the UML specification, to jointly charter the OMG Systems Engineering
Domain Special Interest Group (SE DSIG) in July 2001. 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 as part of
the UML for Systems Engineering Request for Proposal (UML for SE RFP; OMG document ad/03-03-41) in March 2003.<ref name="rfp">{{cite web|author=OMG SE DSIG|title=UML<sup>TM</sup> for Systems Engineering RFP|url=http://syseng.omg.org/UML_for_SE_RFP.htm|accessdate=2006-06-29}}</ref>
In mid-2003 the ''SysML Partners'',<ref>{{cite web|url=http://www.sysml.org/partners.htm|title=SysML Partners|accessdate=2006-06-29}}</ref> an informal association of industry leaders and tool vendors co-chaired by [[Sanford Friedenthal]] and [[Cris Kobryn]], wasorganized establishedan open source specification project to develop the SysML language in response to the "UML for Systems Engineering" RFP.<ref>{{cite web|last=Friedenthal|first=Sanford|title=UML for SE Update - SysML Partners Formed|url=http://syseng.omg.org/SE_DSIG_Status/SysML%20Partners%20Announcement%20to%20INCOSE%20-%20July%2011,%202003.htm|accessdate=2006-06-29}}</ref> The SysML 1.0a open source specification was completed and submitted to the OMG in fourth quarter ofNovember 2005,.<ref name="sysml faq">{{cite web|author=SysML Partners|title=SysML FAQ|url=http://www.sysmlforum.com/faq.htm|accessdate=2006-06-29}}</ref>, althoughAfter earliera draftsseries of the SysMLcompeting specification wereproposals, availablea from"SysML theMerge SysMLTeam" websiteproposal was priorproposed to the submissionOMG ofin theApril specification2006. toThis proposal is now being finalized via the OMG adoption process.
