Very Advanced Systems Engineering with Functional Architectures for Systems - Part II / II


Whoever likes to keep developing systems with market success needs to be in control of system functions, for example, based on an explicit definition of the system’s functional architecture. However, it is usually the system that is sold and not the artifact that defines its functional architecture.  This calls for a lean and easy way to work with functional architectures.

During this webinar, two practitioners of functional architecture work, Tim Weilkiens and Jesko Lamm, will continue the presentation of approaches they started in part I. After a short recap for those who could not attend part I, they will elaborate on the practitioner’s work with the so-called FAS Method for functional architecture.

The application in daily work and the mapping of the method to modeling languages and modeling tools will be in focus, including:

  • Informal techniques based on post-its or paper cards, to be used when running workshops face-to-face or with virtual post-it-boards in partially online meetings.
  • Representations of the needed work items in the SysML modeling language.
  • Traceability from functional architecture up to use cases and optionally further up to storyboards in the modeling tool.
  • Demos of the corresponding modeling tool work, including automation of certain steps to carry out when applying the FAS Method and some tool support for creating functional diagrams from the model and later checking their consistency with the model.
  • A demonstration of a pilot implementation for the upcoming new systems modeling standard SysML v2.

No modeling language or modeling tool knowledge will be required because the demos will speak for themselves.

Take-Away Key Messages

  • Pencil and paper (or the virtual counterpart thereof) may be sufficient means to get quite far with functional architectures.
  • SysML and its successor, SysML v2, provide good means to capture the results of functional architecture work more formally.
  • Traceability and consistency in larger functional models can be maintained well with a modeling tool.


Tim Weilkiens is a MBSE'er by passion. He is a MBSE consultant, trainer, author of many books, owner of the publishing company MBSE4U and lecturer of master courses. He is an active member of the Object Management Group. Tim contributed to the original SysML specification and continues to work on SysML. He is currently co-chair of the SysML v2 Finalization Task Force. Tim is involved in many MBSE activities and has authored several books on modeling, including Systems Engineering with SysML (2008, Morgan Kaufmann). He is also the editor of the pragmatic and independent MBSE methodology SYSMOD - the Systems Modeling Toolbox.

Jesko G. Lamm develops modern hearing health technology as a Systems Engineer. He has been an active member of INCOSE for many years. The focus of his contributions is on the Architecture-related work of the German and Swiss INCOSE chapters, where he is the co-author of many conference papers and working group results. He is a Certified Systems Engineer (GfSE)® and holds a Dipl.-Ing. degree from RWTH Aachen University as well as a Dr.-Ing. degree from Leibniz University Hannover.
