The Two Miracles of Systems Engineering

We have all seen some variant of the famous Sidney Harris cartoon – two people standing at the chalkboard, an incredibly complex series of equations or process flow on the left, a simplification or result on the right, and the words “then a miracle occurs” in the middle. It’s an …

Hitting the Target Audience

The choice of representations in model-based systems engineering (MBSE) turns on the needs of the audience for understanding. The purpose of communication is to express the ideas of the sender in a way that produces a common understanding between the sender and the receiver. Those versed in communication know achieving …
