I am a managing director of the German consulting and training company oose, a consultant and trainer, and active member of the OMG and INCOSE. I have written sections of the initial SysML specification and I am still active in the ongoing work on SysML. I am involved in many MBSE activities and you can meet me on several conferences about MBSE and related topics.
As a consultant, I have advised many companies in different domains. The insights into their challenges are one source of my experience that I share in my books and presentations.
I have written many books about modeling including Systems Engineering with SysML (Morgan Kaufmann, 2008) and Model-Based System Architecture (Wiley, 2015). I am the editor of the pragmatic and independent MBSE methodology SYSMOD – the Systems Modeling Toolbox and VAMOS (Variant Modeling with SysML). In 2015 I have founded the publishing organization MBSE4U.
A comprehensive list of my publications can be found on my oose page (German).
