KO input is only valuable if written by a VP or higher. My boss told me that, after forbidding me for the past year to attend any meeting with a VP.
PS. Even great feedback from VPs is cancelled out by the employee being RE. RE guarantees that RG points will be subtracted every year.
If the system was independently administered by a neutral entity, KO feedback anonymous, YEE not shown, Potential not a factor, the outcome would be extremely different.
EM is a company of processes and procedures with the idea that anyone in a given position can succeed. The outcome of a process is supposed to be repeatable no matter who administers it.
OP seems to be highlighting the fact that the ranking process is not neutral and repeatable, but highly dependent on who is administering it, with built in politics, favoritism, s-xism, and racism.
