This is pretty interesting, because typically when you have departments that are overrepresented demographically that means there is some bias in the hiring. The entire point at DEI, especially at global scale corporations that employ 10s to 100s of thousands of people the KPIs matter because they show the bias of managers or organizations pretty clearly - and guess what at a place with that many people, it definitely doesn't matter if you are white black purple or blue. You are a cog in a machine. The cogs in the machine need to be diverse and there needs to be ample opportunity for diversity of thought, background etc or you start to get echo chambers and fiefdoms based on the buddy system and a complete lack of meritocracy.
DEI wasn't for the small businesses or medium sized companies. It's for companies that have record profits and are massive employers who may have managers or people who work for the firm that are intentionally or unintentionally being bias against people that don't look like them.
