Spec-Driven Development for Software. Coming Soon to Hardware, Too?
In Spec-Driven Development (SDD), the software code is a derived artifact. The idea is not new, but it has been revitalized by AI.
OMG and the EDM Council: Openness Put to the Test
The OMG was acquired by the EDM Council. This is relevant to systems engineering because of the many OMG standards.
Interview with Prof. Bernhard Rumpe: Industrialization with modelling
In this interview, Prof. Bernhard Rumpe talks about the acute industrial crisis and how MBSE can help us overcome it.
Textual model notations are used, not only in SysML v2
Textual model notations build a bridge between text and graphics. SysML v2 is particularly interesting here.
The MBSE triangle: language, tool, methodology
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...
System context: meaning, modeling and practical applications
Every development project has a system context. We should record this explicitly, with or without modeling.
Using ontologies in requirements management: A meta-study
This paper by Diego Dermeval on ontologies shows different approaches to their use in requirements management.
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...
MBSE with ChatGPT: A (scientific) field report
ChatGPT can be used to generate MBSE models from text. PlantUML can be used for visualization.
What is an ontology? And do I need one?
An ontology is the structure of terms, their meaning and relationships. It ensures precision in product development.
The use case: modeling behavior
Use cases are among the best-known types of modeling There is a good reason for this: when we describe something, we are particularly interested in its behavior. And use cases allow us to do this. It's easy to specify successfully with use cases in a short time if a few basic concepts are internalized and a few rules are followed. Therefore...
Is SysML too complicated? And if so, what is the alternative?
When it comes to modeling languages, people's reactions are often extreme: there are people for whom models are far too complicated; then there are those who like to work with diagrams and perceive them as the model; and those who understand modeling languages in depth and build correspondingly complex models that, while impressive, are of little use....
