How do you do laundry on a nine-month trip to Mars? Answer: You don’t. At least, scientists have not yet figured out the answer to this challenge—one of space travels interesting problems. A water-based solution is out of the question—water is heavy and expensive to ship, and what water one …

The Systems Engineering Body of Knowledge* defines a model as “a simplified representation of a system at some particular point in time or space intended to promote understanding of the real system.” There is broad acceptance that models are limited or simplified representations of a reality of interest. There is …

As is often the case, it is the neglect of fundamental principles that is at the root of poor performance. Sports coaches often stress the return to fundamentals—the “blocking and tackling”—as the key to improving team performance. This is a recognition of the powerful effect that adherence to sound fundamental …

Our quest to transition to model-based systems engineering – and the larger transformation of the development lifecycle to digital engineering – centers on moving from relatively low-fidelity documents to higher fidelity, richer representations. In doing so, we can move from the ambiguity of documents to digital clarity, allowing us to …
