Big companies tend to either have separated legal entities or to run each department with their own budget/business goals, which lead to absurdities like having contract to get an engineer from another department as an independent reviewer or long discussion between director-level executive when R&D tells logistic that instead of throwing an expensive but useless part away, R&D can take it for the lab(I’ve seen it, not sure that the money saved on the part was cheaper than the director grade meeting needed to make it happen)
