Metrics are quotas at Amazon. There is a literally a training during your onboarding about Amazon's "metrics culture", and how the only reason you track a metric is if you have a corresponding target for that metric, as well as someone responsible for ensuring that the metric reaches that target. Amazon doesn't just track random metrics for the hell of it. Those metrics and targets are used either for or against you during annual performance reviews, and URA/RA targets are one of the most important metrics for manager-track employees. If that isn't a 'quota', then I don't know what would be.
