I like finding the instances where engineers and designers one-up the financial team.
Examples that come to mind, a tactile coating applied to the never-exposed surfaces of some Alfa ashtrays. Falcon bonnet struts, left and right distinguished by part numbers. Fiat body modules where multiple iterations physically existed with the same componentry and different flashes; rather than using simple logic conditions that did or didn’t send signals based on the KO startup circuitry tests and having one set of code for all… A special mention also to the nameless person in CBS, who in 1966 put an extra zero on a purchase order and they had four years’ supply of one electronic component.
