As you will know I pass some of my time providing my expertise to a major international company. As one of their processes each year we assess the quality of the the staff. Most of the work has been done by my managers and underlings, but now I must look at the results and make sure that they have been assessed fairly. 

The company uses a scheme that rates the staff from 3 (must do better) up to 1 (exceptional)... I feel this is a bizarre and arbitrary scheme. I have adapted my own policy: 3 - very poor, 2 - poor, 2+ - gets by, 1 - comfortably off.
