Model based systems engineering (MBSE) employs information management systems in the form of structured, rigorous and unambiguous models to understand aspects of system development activities associated system requirements, design, analysis, verification and validation. MBSE is being looked at in various applications throughout the project lifecycle to establish approaches and determine benefits to system development activities. This discussion builds upon previous discussions about MBSE at GSFC, laying out a framework and methodology for applying system models to the systems engineering process for a specific Phase A system development activity. The discussion will frame SE processes and demonstrate how a system model is used to capture SE products through model artifacts, and explores where using system models could reduce effort, time and cost in executing SE processes during Phase A.

Biography:

Dave Richardson is currently serving as the Associate Branch Head in the GSFC Instrument and Payload Systems Engineering Branch. After receiving mechanical engineering degrees from the University of Rhode Island, Marquette University and the University of Maryland at College Part, Dave joined GSFC in 2006.

Dave started his career at GSFC in 2006, in the Facilities Management Division, performing roles for project planning, project design and construction, and program management.

Dave learned a broader view of the Agency as an analyst in the Space Technology Mission Directorate, in 2012, where he contributed to the NASA Strategic Plan and captured the strategic alignment of the STMD technology development portfolio within the context of the Agency's overall strategy.

In 2014, Dave joined the Mission Systems and Analysis Division and the Navigation and Mission Design branch. In 2016, Dave moved in the Instrument and Payload Systems Engineering Branch, where he helps manage the payload and instrument systems engineering work and stewards the systems engineering tools and methods efforts.
