But then you need someone to test the nails for standard-compliance, and what metrics should you give them to make sure they do a good job...
- subroutine 7y agoYou can revert to a count-based performance target, and test for compliance based on parcel weight (e.g. a 2-inch finishing nail weighs 0.79 g; if a factory reports 1 mil units, take a random .8 kg sample, check if there's ~1k nails).
- dagw 7y agoThen the factory will just prioritize making sure all their nails weigh the same over any other consideration.
- subroutine 7y agoThey should be prioritizing count (I mentioned that was the performance metric). They actually wouldn't need to "make sure all their nails weigh the same", only that on average they weigh as much as the template. If you can't save time by using less material, and you can't save time by generating fewer units, might as well make the foundry mold match the template, no?
- peteradio 7y agoThese things actually do exist. I couldn't quote them for you but nails are designed to meet a specific function and are stated to meet that function under some penalty. For instance penny nails used for framing a house are made to be somewhat malleable so they don't shear when the house settles. This is certainly regularly tested.
