> quality evaluation is not something that can be boiled down to quantitative measurement.

It absolutely can. For the majority of workers inside an Amazon FC, the job has no decision making in it. Decisions take time, take thinking, and can be made wrong. All of the apps driving work do not offer branches, choices. They direct the associate: do this thing.

The entire job is "do the thing as many times as you can per hour, without doing it wrong". It's almost always the same thing, over and over. The metric they are judged on is their overall rate of doing that job. And mistakes from doing it wrong are found, identified, and tracked back to who did it.

> Judging workers solely based on some rubric will create a class of people who min-max the system and will lower the overall quality of the service provided, while disenfranchising the best employees.

The cases where people have 'gamed' this system usually make the news: people peeing in bottles rather than walking to the bathroom, so that they can keep their rates high. Apart from that kind of insanity, there aren't really any ways to improve the metric except to go faster. And either way. it's a net win for Amazon.
