Engineers are facing increasing challenges in today's product development, because technical systems have been getting more complex in recent years due to the trend towards interconnected products, which are often realized as cyber-physical systems or systems of systems (SoS), and other influences such as an increasing level of globalization and more stringent regulations. New development approaches have emerged to handle this complexity and allow the realization of such complex systems. One of these approaches is Model-Based Systems Engineering (MBSE), is according to INCOSE [6] “the formalized application of modeling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases.”

MBSE is currently widely used during the requirements elicitation and engineering phase at system level and for refining these requirements in the individual sub-levels. Some companies have already opted for an overall MBSE approach; some have started implementing certain aspects of the MBSE approach, such as functional decomposition and system architecture design or verification and validation due to test procedures. The aerospace and automotive industry in particular are giving thought to MBSE methods due to regulatory concerns and boundary conditions, too. 

This presentation outlines an approach in order to deploy MBSE successfully and highlights some best practices from industry and highlights future endeavors when it comes to Advanced Systems Engineering (ASE).
