Biography

Kobryn began his software engineering career in the early 1980s specializing in AI programming languages (Prolog, Lisp, CLOS) and applications (expert systems, natural language processing). He led the applications group at Harlequin Limited that developed the Watson investigative analysis application, which was eventually acquired by Xanalys Limited. [4]

Kobryn is known as an expert in Model-Based Systems Engineering (MBSE) and Model-Driven Development (MDD) technologies. In 2003 he founded PivotPoint Technology, a systems and software engineering services company that focuses on MBSE and MDD technologies. [4] Prior to founding PivotPoint Kobryn held senior technical positions at Telelogic, EDS, MCI Systemhouse, Inference Corporation, Harlequin, and SAIC. Before Kobryn became a software engineer he served as a commissioned officer in both the U.S. Marine Corps and the U.S. Army, and was infantry, armor, airborne and Special Forces qualified. [5]

Kobryn is a member of the ACM, IEEE, INCOSE and AAAI. He chaired large international teams of vendors and users to specify the Unified Modeling Language (UML) 1.1 and UML 2.0 standards for software engineering, and the Systems Modeling Language (SysML) for systems engineering. [6] In recognition of Kobryn's contributions to the UML, the OMG presented him with its Distinguished Service Award in 2000. In recognition of his contributions to the SysML, the INCOSE presented him with its Outstanding Service Award in 2006. In 2007 Kobryn received the SD Times 100 award for the Modeling category on behalf of the SysML Partners open source project that he chaired. [7] [8]

Kobryn received a BA degree from Colgate University and a BSCS degree from San Diego State University (SDSU). His multi-disciplinary graduate studies at SDSU and UCLA explored the synergies between linguistics, computer science and Artificial Intelligence (AI).

Publications

As an expert in Model-Driven Development and Model-Based Systems Engineering technologies, Kobryn has published a book and many papers and articles on these subjects. [9] [10] [11]

StarUML is a software engineering tool for system modeling using the Unified Modeling Language, as well as Systems Modeling Language, and classical modeling notations. It is published by MKLabs and is available on Windows, Linux and MacOS.

UML Partners was a consortium of system integrators and vendors convened in 1996 to specify the Unified Modeling Language (UML). Initially the consortium was led by Grady Booch, Ivar Jacobson, and James Rumbaugh of Rational Software. The UML Partners' UML 1.0 specification draft was proposed to the Object Management Group (OMG) in January 1997. During the same month the UML Partners formed a Semantics Task Force, chaired by Cris Kobryn, to finalize the semantics of the specification and integrate it with other standardization efforts. The result of this work, UML 1.1, was submitted to the OMG in August 1997 and adopted by the OMG in November 1997.

PivotPoint Technology Corporation is a software and systems engineering services company headquartered in Fallbrook, California. PivotPoint was founded in 2003 by Cris Kobryn, a noted expert in visual modeling languages and model-driven development technologies. PivotPoint is best known for its model-driven development consulting and training services, the latter which feature UML, SysML, BPMN and DoDAF workshops. PivotPoint is a founding member and a major contributor to the SysML Partners, the group of software tool vendors and industry leaders that convened in 2003 to create a UML dialect for systems engineering called SysML. In June 2007 the SysML Partners were named a winner in the Modeling category of the SD Times 100, which recognizes the leaders and innovators of the software development industry.

SysML Partners is a consortium of software tool vendors and industry leaders organized in 2003 to create the Systems Modeling Language (SysML), a dialect of UML customized for systems engineering. The consortium was founded and organized by Cris Kobryn, who previously chaired the UML 1.1 and UML 2.0 specification teams, and Sandy Friedenthal, chair of the OMG Systems Engineering Special Interest Group. The SysML Partners defined SysML as an open source specification, and their specifications include an open source license for distribution and use.

Universal systems language (USL) is a systems modeling language and formal method for the specification and design of software and other complex systems. It was designed by Margaret Hamilton based on her experiences writing flight software for the Apollo program. The language is implemented through the 001 Tool Suite software by Hamilton Technologies, Inc. USL evolved from 001AXES which in turn evolved from AXES all of which are based on Hamilton's axioms of control. The 001 Tool Suite uses the preventive concept of Development Before the Fact (DBTF) for its life-cycle development process. DBTF eliminates errors as early as possible during the development process removing the need to look for errors after-the-fact.

Model-based systems engineering (MBSE), according to the International Council on Systems Engineering (INCOSE), is the formalized application of modeling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases. MBSE is a technical approach to systems engineering that focuses on creating and exploiting domain models as the primary means of information exchange, rather than on document-based information exchange. MBSE technical approaches are commonly applied to a wide range of industries with complex systems, such as aerospace, defense, rail, automotive, manufacturing, etc.
