Combined Modeling and Requirements Analysis Speaker Jeff O. Grady, INCOSE Fellow Abstract Jeff Grady will make the proposal that system engineers and software engineers join forces to adopt or evolve a combined modeling capability that all can use to clearly understand a problem space, publish specifications containing the requirements derived from those models, and link up traceability across the HW-SW valley. The modeling artifacts are available today based on the tremendous work accomplished by system and software engineers within the OMG to encourage this combined model but there are some impediments that may make it difficult to gain acceptance in the system engineering community. In this tutorial, the details of the combined modeling approach will be covered in accordance with the following six-hour outline:
The fundamentals of the combined modeling approach include the union of UML and SysML extended to include the specialty engineering scoping matrix to provide discipline for software QAW exercises as well as system and hardware requirements analysis, the three-tiered environmental requirements analysis construct, a common requirements analysis sheet (RAS) as the transform between functional and/or behavioral and product entities planes and capture all requirements that are derived from the modeling work, and a common product entity structure into which product entities flow whether they are identified in response to the application of SysML or UML techniques. A combined software and hardware development process will be offered that respects Sullivan's form follows function notion and applies a top down development orientation. The same transform between functional/behavioral and product entity planes is coordinated across hardware and software so as to encourage improved hardware-software integration. A single specification standard is offered that marries the use case specification to the SRS format for those programs that require published specifications. The case is also made for the alternative where the requirements are accepted as residing within the model as it is extended to develop the design solution that will be compliant due to the continuity of the model. However, there are doubters about such a major change in the system development process. The tutorial will close out on the potential for model-driven development closing this door eventually. Biography Since 1993 Jeff Grady has been the President of JOG System Engineering, Inc., a system engineering consulting firm focused on assessment of current client capability coupled with education leading to planned improvements. Formerly, engineering manager of Systems Development at General Dynamics Space Systems Division working on space transport and energy systems. Other experience over a period of 30 years in industry included: system engineer with GD Convair on cruise missiles; system engineer, project engineer, and field engineer with Ryan Aeronautical on unmanned photo reconnaissance, electronic warfare, ELINT/SIGINT, and target aircraft systems; and customer training instructor with Librascope on underwater fire control systems (ASROC and SUBROC). Served in the U.S. Marines in the aviation communications field. Jeff is a charter member of the International Council on Systems Engineering (INCOSE). He was recognized by his peers as an INCOSE Fellow in 2001, cited for "industrial education in the systems engineering field and for establishing the role of INCOSE as a teaching organization." He was selected as an INCOSE Founder in 2003, cited for "his seminal role in founding NCOSE, his service as its Secretary, his leadership in inaugurating and editing the Systems Engineering Journal, and his major contributions to systems engineering education." Jeff is also recognized as an INCOSE CSEP. His system engineering knowledge has been thoroughly tested as a lecturer and published author. Over a period of 13 years Jeff has developed and presented several hundred system engineering courses and tutorials through universities, short course companies, and by direct sale to companies, in some cases building special courses for ownership by clients such as FAA and Raytheon among others. His company's program undergoes continuous improvement based on experience dealing with clients as a consultant, new research, and critical feedback from clients. After recent consulting experience, for example, with a client using UML in the development of new Army vehicles, he made significant improvements in his requirements course relative to HW-SW integration. Jeff is currently a member of the Purdue University Graduate Faculty. He has lectured in systems engineering programs at or for University of California San Diego, Riverside, Berkeley, and Irvine; Indiana-Purdue University; University of Alabama at Huntsville; John Hopkins University, and Old Dominion University. He has also lectured nationally and internationally on-site at companies. Member of the UCSD System Engineering Advisory Board and continues to teach system engineering courses there. He has also taught many system engineering courses for short course companies including Applied Technology Institute, Technology Training Corporation, Execuspec, and Professional Education International. Author of seven recent books in the system engineering field. His latest book System Verification was published by Elsevier Academic Press in April 2007 and System Requirements Analysis, was published by Academic Press in January 2006. Previously his five other published books included System Requirements Analysis, McGraw-Hill, 1993; System Integration, CRC Press,1994; System Engineering Planning and Enterprise Identity, CRC Press,1995; System Validation and Verification, CRC Press, 1997; and System Engineering Deployment, CRC Press, 1999. Jeff is now doing research on two more books in the system engineering field. Jeff holds a Bachelor's degree in Mathematics from San Diego State University and an MS in Systems Management from University of Southern California. Location California Institute of Technology |
