Five years ago, Erik Herzog and I had the idea for a special conference tour in northern Europe. The Nordic Systems Engineering Tour was and is still a great success. Organized by the local chapters of INCOSE in Finland, Sweden, Denmark, Germany, and Poland it is an event from and for the systems engineering community to share knowledge and to make long lasting contacts with other system engineers. The important dates - Mark your calendars: The Call for Presenters ends at Feb...

The second edition of my book SYSMOD – Systems Modeling Toolbox – Pragmatic MBSE with SysML was published by MBSE4U. It is based on the SYSMOD version 4.1 and SysML 1.4. What's new? Updated the variant stereotypes based on my new book Variant Modeling with SysML (published by MBSE4U, 2016). The variant stereotypes are part of the SYSMOD profile. Added the integration of functional architectures. The modeling of functional architectures is described by the FAS method that is not part of...

Last week I was a panelist together with Bruce P. Douglass and Stefan Hänggi at the SWISSED conference in Zurich. The topic of the panel was “How does implementing Systems Engineering enhance an organization’s competitiveness?”. We had a very good discussion and since I was one of the panelists and not the minute taker I cannot repeat the discussion here. But my preparation notes of the panel are a good source for a blog post and I have turned my bullet...

NoSE 2016 successfully finished in Warsaw today. The 4th Nordic Systems Engineering Tour was again a great event. The tour speakers started in Helsinki at Monday, headed then to Stockholm at Tuesday, Copenhagen Wednesday (in collaboration with the Systems Engineering Spring School), Hamburg at Thursday and finally Warsaw. Each location was enriched by talks of local speakers. I had the pleasure to be a local speaker at two locations: Hamburg and Warsaw. If you were not at any of the events, you...

The figure shows the Gap of Slackness. The vertical axis represents the typical challenges for product vendors. They are for example more innovation, less time-to-market, less cost, and perfect quality. You can certainly mention more of them for your domain. The system curve along the time always increases and reflects the steadily increasing demand for improvements. The globalization and accompanying worldwide dynamics change the linear slope of the curve to an exponential slope. More competitors with different backgrounds make the markets...

End of 2015 I have founded the publishing platform MBSE4U for MBSE books. A few days ago I have updated my social media profiles with MBSE4U and got a lot of responses. Therefore, a few short notes to clarify things. The mission of MBSE4U is to provide books with up-to-date content about model-based systems engineering.  It is part of my authoring activities that I practice since more than 10 years. You find more details on the MBSE4U page. To avoid any...

I have just published my new book „Variant Modeling with SysML”. It presents a method for modeling variants of system requirements and system architecture artifacts with standard SysML and a standard SysML modeling tool. About 10 years ago I published the method and SysML profile for the first time. Since then I have had many discussions and experiences with that approach. Now it was time to publish a comprehensive description of the approach and to give the method a home. There are...

The association is a strange model element. And many myths about the association are going around. For example, think of all the discussions about the meaning and difference of aggregation and composition. Did you know that the concepts of aggregation and composition have not much to do with associations? I will not explain the association in detail in this blogpost. My primary intent is to get rid of the association. Ok, in some scenarios the association is necessary and useful. But...

I am happy to announce my new book about SYSMOD. SYSMOD is a MBSE toolbox for pragmatic modeling of systems. It is well-suited to be used with SysML. The book provides a set of methods with roles and outputs. Concrete guidances and examples show how to apply the methods with SysML. Today SYSMOD or more specifically customizations of SYSMOD are used in many industrial projects. Many years ago I have found the Systems Modeling Toolbox (SYSMOD) while I worked together with other MBSE experts on the...

As co-founder and a member of the organizing committee I am proud to announce another NoSE tour: For the fourth time the Nordic Systems Engineering Tour will be on tour from May 23rd to 27th. The tour is a one-day conference with four different venues. Tour speakers will present at all venues, local speakers only at a local event. Tour speakers have the opportunity to give a talk in four different countries to a large audience. The tour starts in Helsinki (23rd), then Stockholm (24th), Copenhagen (25th), and...
