I heard a story a few years back about a company that went to 100%
testing of all components. The production department got a shipment of
fuses with the QC statements that they all blew at the proper
amperage.


That isn't how you test a fuse. There is QC, by monitoring the
temperature with an IR camera or thermometer. Some Defense contractors
were required to do 100% testing on components, because the product was
for mission critical use. Cincinnati Electronics had a couple people
who took reeled passives and ran them on automated test fixtures. If a
part was out of spec, it was automatically cut from the T&R. If the
percentage was too high, the whole reel went back to the vendor.
