Models – Involved or Foundational?

by zscott

Zane Scott, Vitech Vice President of Professional Services

In the world of model-based systems engineering there is a surprising amount of confusion over the role and concept of models. One would think that a concept important enough to be contained in the very name of the practice would have a well-settled definition. But such is not the case in MBSE. Still at issue is what it takes to be the kind of model on which systems engineering can be based. More...

Self-Inflicted Wounds on Our Journey to MBSE

by dlong

By David Long, Vitech President

Over the past six weeks, I have had the pleasure of participating in a wide range of systems engineering forums, workshops, and conferences in multiple regions and across diverse domains. I continue to be impressed by the energy and passion that permeates these events and all those engaged in moving systems engineering forward toward a model-based discipline. At the same time, I am disappointed by some of the continued missteps I see. These easily avoidable mistakes drain energy and continue to slow our progress toward the ultimate goal of moving the practice and profession of systems engineering forward. If we can relegate these challenges to the past, we can certainly accelerate our progress. More...

Fit for Purpose – The Choice of View

by zscott

Zane Scott, Vitech Vice President of Professional Services

One of the quandaries regularly presented to systems engineers is which view or combination of views to use when representing the system model to others. In today’s practice, there is a blessing – and a curse – in the sheer number of views available for this purpose. The choice is varied and nuanced so views can be targeted to the job at hand. Despite that, engineers often make the choice of views based on their own personal preferences or pattern of practice.

By being intentional about the way we represent our system model, we can leverage the power of the model itself to communicate the principles and rationale behind the design. To begin, we consider what a view is in the context of systems engineering. More...
