What Digital Engineering Is NOT
Clearing the Fog
Digital engineering is a term that gets stretched, misused, and conflated with adjacent concepts. Before going further, we need to be clear about what digital engineering is not — because the misconceptions are as important as the definition.
The Confusion Is Not Accidental
There are reasons these conflations persist:
Vendors benefit from narrow definitions
If a PLM vendor can convince you that buying their platform equals "doing digital engineering," they've won your budget. The broader the real definition, the harder it is for any single vendor to claim ownership of it.
The DoD definition was foundational but incomplete
The 2018 DoD Digital Engineering Strategy was the first major institutional definition. It centered on "authoritative sources of system data and models" — which naturally led organizations to equate DE with MBSE, since MBSE was the most mature model-based practice available. The definition didn't anticipate how quickly AI would become relevant.
"Digital" is overloaded
In business, "digital" means IT modernization. In engineering, it should mean something more specific. But the shared word creates constant conflation.
A Litmus Test
When someone claims to be "doing digital engineering," ask three questions:
-
Are computation, data, and AI native to how you practice engineering? If they're used occasionally or by separate teams, it's not digital engineering yet — it's computer-aided engineering.
-
Are you forming associations across information streams? If requirements, design, test, and operations data live in disconnected silos, the "digital" part isn't working.
-
Can you model, predict, and optimize computationally? If decisions are still made by reviewing static documents and debating in meetings, the practice hasn't changed — only the file format has.
Assessment
An aerospace company uses SysML models for system architecture, but the models are maintained by a dedicated MBSE team and are not connected to simulation, test, or operational data. Which of the following statements are true? (Select all that apply)
Select all that apply
Apply the three-question litmus test from this lesson to a specific engineering organization or project you know. For each question, provide a concrete assessment — not just 'yes' or 'no,' but evidence for your answer.
