What Makes a Good MBSE Model?

In the world of model-based systems engineering (MBSE), there is still a fair amount of confusion around what makes a good—or even acceptable—MBSE model. George E. P. Box, the English statistician, famously observed, “All models are wrong, but some are useful.” He further clarified that idea with this expansion, “Remember …

The Forgotten System

In any system design project there are always three systems of importance. The first of these is what we call the system of interest or the solution system. That is the system we intend to design. (Note: For the purposes of this discussion, the name “system of interest” may be …

The Importance of Architecting our Modeling Environment

Systems engineers and systems architects have many architectures of which they need to be aware: there’s the architecture of the system-of-interest (or system under design), the architecture of the larger system in which the system-of-interest must operate (the context system), and the architecture of the enabling system (the enterprise or …

MBSE: Simple, Complicated, or Complex?

After 15 years of practice, there is still a great deal of confusion surrounding model-based systems engineering – not only what MBSE is but also the difficulty of application. Some see MBSE as simple, the only possible way they could imagine engineering a system of any scale. Others perceive it …
