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 …

Precision and the False Choice

By David Long, Vitech President Just like simplicity, not all precision is helpful. Heresy? Not for engineers. Engineers are taught to use the appropriate degree of precision for the circumstance at hand. Unfortunately, as systems engineers, we too often forget those lessons. The quest for precision can lead us astray, …

The Need to Suboptimize Systems Engineering

By David Long, Vitech President A good systems engineer working on a project should seek to suboptimize systems engineering. A heretical statement? Not really. In fact, the path to optimizing systems engineering lies in suboptimizing systems engineering. It may sound paradoxical, but it’s true. The purpose of systems engineering is …
