Even if your intent is to maximize income in customer support, you often don’t have the market option to do that. I have seen (and even worked at) places where chat support, phone support, and support administrators have a quota of chats, calls, or ticket responses and make bonuses based on how much they exceed their numbers. Unfortunately sometimes that results in people updating tickets several times an hour saying things like “we’re still looking into this and haven’t forgotten you” without actually looking into anything.

One place I worked I tried to move the quota system more towards being the final response on a resolve issue, but upper management didn’t want to ever judge whether an issue was resolved even when the customer said they were happy. They did incorporate an NPS query for every interaction, though, and a multiplier against the volume-based quota. Unfortunately that favored people who were good BS artists when lying to the customer about looking into things.

The fallout from the above paragraph was that quality, caring staff would get punished for actually solving customer problems.

Almost every other role is at least one level removed from putting cash in the company's account, which is what leads to the shenanigans you described with metrics that are a poor proxy for revenue generation (and/or are too easy to game).
