Changes in technology, economy and society create challenges that force us to rethink the way we develop systems. Model-Based Systems Engineering is an approach that can prove catalytic in this new era of systems development. In this paper we introduce the idea of the modeling in order to realize the vision of Model-Based Systems Engineering and especially we focus on the trade-off path of this hub. For that purpose the design capabilities of SysML are extended by integrating it with
