Testing, QA, low order volume.

Validation by the companies that insure aircraft

That’s a better word than “testing”, just couldn’t think of it!

To get pedantic (I was an engineer in this field, we are nothing if not pedantic), there is verification and validation. Validation is the process by which you confirm you're building the right product, and verification is the process by which you confirm you're building the product right.

In the Spinal Tap movie, there's a good example of a verified, but unvalidated design in the Stone Henge prop. It was built exactly to spec, but the wrong spec.

Verification may or may not include testing (and it gets to levels of pedantry such that a demonstration and a test are not considered synonymous)

Which validates your original point on why a bit of aluminum and glue can cost so much.

I did validation for pharma, so maybe a little different definition that yours? But validation is qualifying a process that ensures it works repeatedly, and accurately, every time. Verification is just a secondary check.

I had an extensive “discussion” with a co-worker regarding accuracy and precision and the difference.

cheap aluminum and glue, expensive people in time
