Functional architectures are a mean of technology-independent system modelling.

The FAS working group aims to gather experience in the application of existing methods for the development of functional architectures and to improve the methods.

The focus is not only on the methods themselves, but also on their application in model-based system modelling with SysML.

The working group wants to be able to usefully and efficiently implement the methods in practice with specific SysML modelling tools.
