On the #OceanGate sub.
Early in my career I worked for a commercial company that had engineering contracts with the Navy. The level of engineering specifications, design docs, test planning, and testing and retesting was enormous for the projects that I worked on.
Peoples lives were at stake. An the effort was warranted.
When I moved away from government projects into the commercial/consumer world I was shocked at how little, if any, of that effort went into commercial product development.
All of those efforts are used to identify and test boundary conditions, mistaken assumptions, surprising human interactions, and many more things that designers and developers miss initially.
We're starting to hear comments from insiders about design and testing flaws of the OceanGate sub.
Commercial efforts in complex areas like AI, driverless cars, air craft and submersibles are good. But they must be held to the same standard as government efforts, e.g. NASA. Cost control is not an option.
