The eXpress Diagnostics Model is effective for all levels of the design architecture and can be expanded or enriched to facilitate the Diagnostic Design or the Sustainment objectives at any time.
The approach for initiating towards the goal of achieving diagnostic effectiveness for any design begins with identifying where we are in the design development or design support lifecycles, while also considering the diagnostic or sustainment requirements or objectives. The eXpress model captures and extends diagnostic expertise regardless of where we are in the design or sustainment lifecycles and for any sustainment implementation.
One of the foremost challenges in large system design is keeping the engineering effort scalable. This is typically where engineering software becomes invaluable. As such, the question becomes, “How scalable is the software you are using?”
