Topic: Pragmatic application of model based system development practices across the ISO/IEC 15288 Systems life cycle processes
Speaker: Geoffrey Shuebrook, Systems Engineering Manager, Decisions Sciences International Corp
INCOSE International has established a 5 year objective to “accelerate the transformation of Systems Engineering to a model based discipline”. In support of this objective we are pleased to have our own Geoffrey Shuebrook talk to us about pragmatic applications of model based system development. Geoff has a passion for model based systems engineering and will present a lively talk on its pragmatic use.
All INCOSE members and interested friends are encouraged to join us for this informative and useful presentation. Looking forward to seeing you.

Abstract:
An approach to managing the complexities of developing software intensive systems is to employ model based development practices. What are model based development practices? How do these practices change the fundamentals of developing a system? How does modeling impact product cost, schedule and quality? As compared to documents, why do models support engineering activities more effectively?
The current document centric artifacts resulting from the execution of technical development processes,as described by the ISO/IEC 15288:2008 Systems and Software Engineering – System Life Cycle Processes, can be a staggering extent of disjointed serialized information. The sheer extent of document centric technical data packages is likely to inhibit effective management of the cost, schedule and quality of system development. Locating information in a document centric technical data package, even when well structured, can be an arduous task. Maintaining the technical data package is costly and challenging. In a model centric system development approach, the execution of technical processes results in a cohesive collection of data. Model elements are defined once and used as many times as required throughout the technical data package. Model based practices provide the opportunity to link every model element to other model elements to provide a richer context for a product’s technical data.
In model based development practice we may apply the Unified Modeling Language (UML) standard as well as other domain specific languages that are extended from UML (e.g., Systems Modeling Language (SysML), UML Testing Profile (UTP), Software & Systems Process Engineering Meta-Model (SPEM)).
Employing standards based modeling languages forms the basis for model centric artifacts, aides in the management of complexity, and enhances the quality of communication. Model centric practices provide a more accurate conveyance of data from life cycle stage to life cycle stage. By accurately conveying information an attendant gain occurs in the management of cost, schedule, and quality.
Speaker Bio:
Geoff Shuebrook started his career in electronics and engineering at the age of 16 with his first job as a technician repairing professional and consumer audio electronics at a small cottage business.
Schematics were his first introduction to modeling. During the ‘70s, a 30 year career in radar began in the United States Marine Corps. Geoff has maintained a host of radar systems (UPS-1B, TPS-22, TPS-63, TPS-32) as well as contributed to the design and development of General Electric’s and now Lockheed Martin’s TPS-59, Advanced Hawkeye, FPS-117, TPS-34, and the Australian Over the Horizon radar system JORN. In 2008 Geoff’s career transitioned to space based systems where he was responsible for integration and test of the Transformational Satellite Communications System (TSAT) Mission Operations Systems (TMOS) and the Space-Based Infrared System (SBIRS) Ground segment.
Most recently Geoff joined Decisions Sciences International Corporation as their Systems Engineering Manager developing a passive cargo scanning technology aimed at the detection of nuclear and radiological threats hidden in international shipping containers. While with Lockheed Martin, Geoff was a member of the Advanced Engineering Practices organization and was responsible for the development of corporate model based testing practices.
