Systems engineering requires a very broad knowledge base. This can be found in this category.
Traceability in requirements management and systems engineering is now a well-understood topic. But do we have traceability for what happens "before"? This refers to traceability to interviews, meeting minutes or legacy systems. This traceability becomes more important as complexity increases. In this respect, I found the recently published meta-study by Julia Mucha, Andreas Kaufmann and Dirk...
Two key aspects of MBSE are the modeling of behavior and structure. With SysML, the structure is modeled with blocks and the behavior with activities. Allocation is the process of linking behavior and structure. Here is a small example.
To practice Model-Based Systems Engineering (MBSE), we need a foundation consisting of language, tool and methodology. SysML is the most popular, but not the only language. There is also a lot of choice when it comes to tools and methods. In the following, we take a closer look at the three elements and also give a few practical examples of...
The block is one of the best known and most important elements of SysML. However, in practice, I often see confusion and errors in its use, especially on the whiteboard, particularly among beginners. This article is intended to help beginners in particular not to get into the wrong habit and to use the SysML block themselves as quickly as possible. Modeling the system context is...
Every development project has a system context. We should record this explicitly, with or without modeling.
Version 2 of the Systems Modeling Language (SysML v2) is currently generating a lot of activity. The standard was recently adopted and manufacturers are working on tools. Many in the systems engineering community are now asking themselves: Is SysML v2 a game changer? Will everything simply continue as before? Or will the standard even die out, as users...
Those readers who have 20 or more years of professional experience can certainly understand my perception: In my youth, I had a high level of respect for engineers. Their knowledge and ability to master technology was reserved for only a few. And required a long apprenticeship. That has changed: Technology is now accessible to everyone. Universities put their courses online...
The keynote speech at this year's Systems Engineering Day (TdSE) was given by Nico Michels. He is responsible for the Digital Enterprise & Academics division at Siemens Digital Industries Software. The topic: Sustainability for companies and the role of systems engineering. He provided important impulses to help decision-makers understand the importance of systems engineering for sustainability....
Michael Pierce from TSP has written an essay with his colleague Bruce Cameron in which he criticizes SysML. On the one hand, it is worth reading for organizations that are considering the strategic use of SysML. Because many of the points are quite valid. On the other hand, I don't think all the criticisms are justified, at least not without qualifying them further. Nevertheless...
This paper by Diego Dermeval on ontologies shows different approaches to their use in requirements management.
In his presentation at TdSE 2023, Michael Jastram will show how AI can act as an intermediary between humans and system models.
This November, the Society for Systems Engineering (GfSE) is organizing two interesting events. Reason enough to briefly report on them: The systems.camp Nord will take place in Hamburg on 11.11.2023 and the Tag des Systems Engineering (TdSE) on 15-17.11.2023 in Würzburg. I will be giving a presentation and a tutorial at TdSE.
