Variant Management in CORE and GENESYS (Part I)

When teaching classes on model-based systems engineering, I am frequently asked about methods to manage different system configurations in the model. Most engineers are very comfortable thinking in part structures, and while this is a critical aspect of systems engineering, it’s not the whole story. To answer the question and …

9 Imaginary Roadblocks to MBSE

For over ten years, the systems engineering community has been focused on the transformation from document-centric to model-based techniques. In terms of the Roger’s innovation adoption lifecycle, we are beyond the early adopters, in the early majority, and moving towards the tipping point where model-based systems engineering becomes the expected …

Pulling Threads: The Value in Systems Engineering

There are two great miracles in systems engineering – where the requirements come from and how you get from requirements to implementation. Where requirements come from is a topic for later (it need not be a miracle or a mystery). As for moving from requirements to implementation, that requires a …

Understanding the Foundations of Model-Based Systems Engineering

“There is NO SUCH THING as non-model-based engineering” Zane Scott, Vitech Corporation Vice President of Professional Services An interesting quote when you consider systems engineering has spent the last ten years obsessed with the transformation to model-based systems engineering (MBSE). But Zane is exactly right. Engineering has always been, and …
