If Callaway sold, say, 50,000,000 golf balls in a year, and they had a .0001 failure rate, there would still be 5,000 imperfect Callaway golf balls floating around out there. Now you and I would hate to end up with one of those 5,000 imperfect balls, because that's potentially $4 we're pumping into the woods despite being well-struck. But the head of any quality control department would love to have a success rate of 99.999% played out over 50,000,000 products.
That is between 5 and 6 sigma. 6 sigma is the gold standard for manufacturing and extremely difficult to achieve. While 5,000 sounds like a lot, that would be an absolutely phenomenal QC number. 100% perfect is impossible due to cost constraints.
