Spaghetti modeling with MBSE: Not like this!
Spaghetti modeling is a common mistake when using MBSE. This checklist helps to avoid mistakes.
SysML: Avoid spaghetti models with the right package structure
It is amazing how quickly the number of elements in a system model grows. It is therefore essential to structure them correctly from the outset. Otherwise we quickly end up with "spaghetti models". This refers to models that look like a ball of spaghetti and are therefore difficult to understand. But almost all modeling languages, including SysML, give us...
Practical tip: Textual requirements with PlantUML
In many teams, textual specifications are still used instead of modeling. I still see this frequently, even in the context of very technical requirements. For example, I still often see embedded systems where state machines are described in text. These are situations where a picture can say more than 1000 words. But the IT...
What exactly is MBSE?
I have already written about MBSE several times in this blog, and most readers are probably aware that this refers to Model Based Systems Engineering. And I'm sure many readers also have a rough idea of what it means. Nevertheless, there are many ambiguities and misunderstandings. For example, that MBSE is also possible without SysML, or that MBSE...
18 things you can do with system models
System modeling is a powerful tool that can be used to improve many aspects of systems engineering, from traceability to change management to test case generation. But there is also a dark side to modeling: it can quickly become an end in itself without clearly defined modeling goals. Chaotic, hard-to-read models can cause more problems than...
Models instead of requirements? Eight arguments for the best of both worlds
This was the - admittedly provocative - title of my recent session at the RE-Barcamp in Cologne. Among other things, this question was triggered by the exciting world cafe at the SE Get Together at oose. It was about the question of what "requirements modeling" actually is. We came to the conclusion that modeling can be applied in two ways in this context.
What has happened to SysML in the last seven years
The OMG operates a number of wikis that contain interesting topics and information. Today I would like to present a report that is a little old, but still contains exciting insights. It is a survey from 2009 on the use of SysML. First of all: Compilation of SysML RFI- Final Report....
Review: Model-Based System Architecture
This sophisticated book describes an approach for the development of complex systems with MBSE. It uses SysML as notation.
Interview with Tim Weilkiens about SysML
As a multiple-time author of books on SysML and the originator of the SYSMOD toolbox, Tim Eilkiens has a lot to say about Systems Engineering.
What you need to know about SYSMOD
SYSMOD by Tim Weilkiens sees itself as a „toolbox for pragmatic, model-based systems engineering.“
