That is precisely my point. If the error was in the design, only the three owners of surviving 825s need to worry. If the error was in the construction, every Oyster owner has to worry because if Polina Star was laid up badly by two blokes in a shed, their prides and joy could have been laid up equally badly by the same two blokes in the same shed.
Design and manufacture are not supposed to be isolated from each other. Designing stuff that can't be made with the processes you have is a design failure. You have to design the process as well as the product. On the production side, you have to have your processes good enough to build to what you've signed up for. In my world, designing something to be built with a different process, you build some prototypes to establish the limitations of the process.
We also have QA people whose job it is to be sure things are built to the design.
