After my performance review, I talked to my boss and my boss's boss, and asked them if that's really what they wanted me to do, ie. fulfill these arbitrary metrics or if they wanted me to work on whatever made the team better. They said no, of course not, but a good engineer should be able to fulfill those metrics and make the company better. I explained the situation, that the ops person left and they haven't hired anyone to take over, so I'm left holding the bag and they refused to acknowledge it, so I quit.
