Given the hype and the types of people that push this shit, I can't imagine any fruitful KPIs being applied. A good KPI should be hard/impossible to game, regularly tracked, and should have understood limits or action triggers (i.e. what result from a KPI is acceptable vs needs improvement).

Had a yearly review where one of my metrics was decreasing NCRs. The numbers showed more than a 25% reduction in NCRs from the previous year when my goal was like 5%. Of course this was over covid and that weren't accounting for volume of orders which plummeted that year. On paper I did fucking phenomenal.
