While complex systems transform the landscape, the Systems Engineering discipline is also experiencing a transformation to a model-based discipline. In alignment with this, one of the International Council on Systems Engineering (INCOSE) strategic objectives is to accelerate this transformation. INCOSE is building a broad community that promotes and advances model based methods to manage the complexity of systems which seamlessly integrate computational algorithms and physical components across domains and traditional system boundaries. This paper covers contextual drivers for transformation as well as challenges, enablers, and INCOSE resources aligned with accelerating the transformation of Systems Engineering to a model-based discipline.
