Factory workers make mistakes all the time. It's normal.

The number and magnitude of mistakes they make depend a great deal on
corporate and social culture.

I recall Akio Morita describing such a problem. Sony was building Trinitrons
in both Japan and the USA. In both countries, the tubes had to meet the same
tolerances. Nevertheless, the company found that the Japanese tubes were
always far closer to perfection than the USA tubes.

Finally, management figure it out. The Japanese always tried to get things
perfect, no matter what the accepted tolerances were, whereas the Americans
didn't care whether it was perfect or not, as long as it fell within the
tolerances.

To fix this, Sony made the tolerances far tighter for the USA tubes. Their
quality then improved significantly.

All of which was stupidity on Sony's part.

All things have a tolerance and tighter tolerances increase costs.

If Sony needed tighter tolerance they should have originally specified
tighter tolerances instead of ****ing and moaning that stuff made to
their specified tolerance wasn't "good enough".

It was all about culture.

Wrong, it is all about getting the specifications to be what is really
needed in the first place.

That is basic engineering.
