1 SysML & Industry: Improving Systems Engineering By Richard Mark Soley, Ph.D. Chairman and CEO Object Management Group, Inc.

2 What is SysML? The OMG Systems Modeling Language is: a general-purpose graphical modeling language for specifying, analyzing, designing, and verifying complex systems, using model-based systems engineering Those systems may include hardware, software, information, personnel, procedures, and facilities In particular, the language provides graphical representations with a semantic foundation for modeling system requirements, behavior, structure, and parametrics, which is used to integrate with other engineering analysis models.

3 Motivation Systems Engineers needed a robust language for analyzing, specifying, designing, verifying and validating systems Many different modeling techniques existed Behavior diagrams, IDEF0, N2 charts, A general purpose language must: satisfy a broad set of modeling requirements (behavior, structure, performance, etc.) integrate with other disciplines (software, hardware, process, etc.) be scalable be adaptable to different software engineering domains be supported by multiple, interoperable tools

4 What is SysML? OMG s Systems Modeling Language Standard Expressed as a UML Profile, extending UML far beyond software It s for Specifying, Analyzing, Designing, and Verifying complex systems that may include Hardware, Software, Information, Personnel, and Facilities First major users: Military and Aerospace Eleven supporting vendors listed; more coming

5 What is SysML? A graphical modeling language adopted in response to the UML for Systems Engineering RFP, developed by the OMG, INCOSE, and AP233 Formally, a UML Profile that represents a subset of UML 2 with extensions Supports the specification, analysis, design, verification, and validation of systems that include hardware, software, data, personnel, procedures, and facilities Supports model and data interchange via XML Metadata Interchange (XMI ) and the evolving AP233 standard (in-process)

6 Background Joint INCOSE / Object Management Group (OMG) Initiative to extend UML to SE Systems Engineering Domain Special Interest Group (SE DSIG) began in Sept 01 Aligned with ISO AP-233 Systems Engineering data interchange standard to support tool interoperability UML for SE RFI issued in 2002 UML for SE RFP (ad/ ) issued March 28, 2003

7 OMG s Mission Since 1989 Develop an architecture, using appropriate technology, for modeling & distributed application integration, guaranteeing: reusability of components interoperability & portability basis in commercially available software Specifications freely available Implementations exist Member-controlled not-for-profit

9 OMG s Best-Known Successes Common Object Request Broker Architecture CORBA remains the only language- and platform-neutral interoperability standard, and the basis for the DDS real-time publish & subscribe standard Unified Modeling Language UML TM remains the world s only standardized modeling language Common Warehouse Metamodel CWM TM, the integration of the last two data warehousing initiatives Meta-Object Facility MOF TM, the language-defining language XML Metadata Interchange XMI TM, the XML-UML standard

10 Why UML? UML is de facto standard within software engineering community (more than 75% adoption in software development organizations) UML is extensible through its profile mechanism, and can be adapted to support SE requirements UML tools, textbooks, training, education & certification are widely available OMG standardization process supports UML customization for specific domains (e.g., systems engineering)

11 INCOSE/OMG Joint Initiative OMG Systems Engineering Domain Special Interest Group chartered by INCOSE-OMG initiative in July 2001 create a semantic bridge between ISO standard and ISO/IEC UML standard create UML extended modeling language for specifying, designing, and verifying complex systems using profiles, or other extensibility mechanisms. provide capability for rigorous transfer of specifications and related information among tools used by systems, software and hardware engineers bridge the semantic gap, the professional engineering discipline gap, and the training gap that exists between systems engineering and software engineering

12 SysML Partners Informal partnership of industry, vendors, government organized in May 2003 to respond to UML for Systems Engineering RFP define Systems Modeling Language (SysML ) to customize UML 2 to support the specification, analysis, design, verification and validation of complex systems Partners Industry American Systems, Astrium Space, BAE SYSTEMS, Boeing, Deere & Company, Eurostep, Israel Aircraft Industries, Lockheed Martin, Motorola, Northrop Grumman, oose.de, Raytheon, THALES Government DoD/OSD, NASA/JPL, NIST Tool Vendors Artisan, Ceira, Gentleware, IBM/Rational, I-Logix, PivotPoint Technology, Popkin, Project Technology, 3SL, Telelogic, Vitech Liaisons and Organizations AP-233, CCSDS, EAST, INCOSE, Rosetta
