Model-Based Systems Engineering (MBSE) is seen as a key enabler for the successful development of complex systems. In its Vision 2025, the International Council on Systems Engineering (INCOSE) sees MBSE as the standard approach in future Systems Engineering.

You will learn and experience the methodological foundations of model-based system development according to the FAS (Functional Architectures for Systems) method within a compact, practice-oriented training. You will learn the international standard OMG Systems Modeling Language (OMG SysML“) and receive valuable first-hand tips for your daily work. We at oose are co-developers of SysML and actively involved in numerous MBSE projects.

Systems primarily provide functions to their users, but are mostly developed component-oriented by their engineers. The too early focus on the physical component, e.g. gasoline engine, and not on the function, e.g. generating propulsive power, slows down innovation and prevents synergy effects.

Using the Functional Architectures for Systems (FAS) method, the training leads you from the system idea, through an use case analysis and requirements, to an implementation- and technology-neutral functional system architecture that is stable over many product generations. Based on this you make further design decisions to derive a physical system architecture with concrete components and to detail and model these further. With the help of sequence diagrams and state diagrams you specify system behavior and derive the interfaces that are required to enable this behavior.

You will apply your learned theoretical knowledge directly to a consistent, practical case example, which you design and discuss together with the other attendees during the training. Focused on the essentials, you will work with SysML on flipcharts and metaplan walls. You will experience the FAS method using a creative card technique. Your trainer will show you in a common SysML modeling application how to create the system model using SysML in a software tool.

We are co-developers of the FAS method. As supplementary material you will receive the book „Model-Based System Architecture“ co-written by our trainers Tim Weilkiens and Stephan Roth (Wiley, 2015). The book contains a detailed chapter on the FAS method.
