You need a sponsor.
A low ranked person will be justified to keep low ranking because not put forth special effort to achieve more.
A top quintile sponsored person with exact same PDS will be justified to keep in top quintile because EM Management “did not provide a sufficient challenge”.
I have seen a sponsored useless person whose only accomplishments were 6 PowerPoint presentations packs for a VP go from 81 to 84 while another person that put forth superhuman effort and saved EM millions of dollars stayed at 19, not even lifted out of bottom quintile for such an amazing effort.
Find a sponsor is key to success at EM.
EM puts thousands of man hours into defining a level playing ground and promoting the ranking system as fair, then VP’s and HR abuse the system by moving certain chosen people to the top despite lack of knowledge and near zero performance.
Move them every 2 years before they are expected to master any position. Move them quicker than 2 years if any catastrophe could be blamed on them. Inform them that they are chosen and have a sponsor just to increase their arrogance.
