Two days of PREEvision: New perspectives on E/E architectures and data models

How do different systems engineering approaches differ, and what impact do they have on day-to-day development work?

These questions were explored by part of our team during a two-day training course at Vector Informatik in Stuttgart.

The focus was on PREEvision, an established development platform for E/E architectures and Model-Based Systems Engineering (MBSE). The training was particularly interesting for our team because, through our project work, we are very familiar with Siemens Capital, giving us the opportunity to compare different perspectives on development processes.

While the Siemens Capital environment describes much of the information through diagrams and their relationships, PREEvision places the underlying data model at the center. This approach opens up new possibilities for the structured management and interconnection of development information.

One of the most impressive aspects was the seamless linkage of requirements, functions, and design artifacts within a central model. This provides significant benefits in terms of traceability, consistency, and transparency across different stages of the development process.

At the same time, it became clear that a centralized modeling approach also introduces new challenges. Topics such as data maintenance, model consistency, governance, and integration into existing tool landscapes become increasingly important.

These discussions were exactly what made the training especially valuable. Exchanging views on different approaches helps us evaluate methods and tools not in isolation, but within the context of real-world development processes.

For us, the event was an excellent opportunity to expand our existing knowledge and gain new perspectives on E/E architectures, MBSE, and digital engineering processes.

We would like to thank the Vector Informatik team for the hands-on training, the engaging discussions, and the open exchange of ideas.

We look forward to applying the insights we gained to future projects and technical discussions surrounding wiring harnesses, E/E systems, and engineering systems.
