We all understand that our complicated world is giving way to a more complex one. We also recognize that our systems engineering techniques used to create modular designs are breaking down as we deal with new levels of complexity. It seems we don’t talk so much about modularity and its …

We’re told risk is at the interface. But, the term “interface” conflates many ideas, and we often focus on the wrong problem. To correct that, we should consider three perspectives on connectivity: logical connectivity, physical connectivity, and behavioral connectivity. Allow me to demonstrate with an example of a multi-point message …

What makes for good systems engineering? We all know how difficult systems engineering is, but how well are we doing? As I think about maturity levels of organizations, I realize that definitions in the community can be rather heavy on process. I maintain that, although formal processes are best, organizations …
