A work-centered perspective on research needs for systems engineering with models.

Compared to document-based systems engineering (SE) models, IT-enabled ones can introduce radical changes in how SE is practiced. Such models are increasingly important today, but how well do we understand their use, impact, and issues? Real-world cases are helpful but tell us little about how and why models work (or don’t), their suitability for a particular context, or how to guide selection and use. Lacking sound knowledge and theory, we cannot assess the value of Model-Based Systems Engineering (MBSE) [1] or predict its outcomes [2] . Instead, we rely on heuristics and judgment, e.g., to make process tailoring decisions [3] . Our motivations include identifying core research needs, provoking discussion on key issues and questions [4] and generating interest by applied and theoretical researchers, including from outside engineering. Other authors have noted that SE would benefit from broader research methodologies and methods (e.g., [5]; [6] ) and greater participation by non-engineering disciplines (e.g., [2]; [7] ). This paper identifies MBSE research topics culled from literature and briefly discusses some key ones based on a work-centered organizational approach with the goal of sparking interest in foundational research.
