I agree with you, but in huge organizations like Kaiser Permanente there doesn't seem to be any good solution. For management at scale there are multiple levels of organizational hierarchy between the decision makers and the individual contributors (like nurses directly dealing with patients). So they need some kind of systematic way to compare employees who work under different managers. Just relying on managers to rate their own direct reports based on empathy and common sense doesn't work well at scale, either.
