Perils of Ratings

Numeric ratings are one of the most abused components of any measurement and assessment system. They make people angry, destroy fragile working relationships, make one employee judge another, and create an artificial, thoroughly uncomfortable situation for both the rater and the person whose work is being rated.

The wonder to me, the way most numeric rating systems are designed, is why you would expect anything different from their use. If an organization takes unsubstantiated, undocumented, uncommunicated, secret numbers and springs a numeric rating on employees periodically, expect the worst.
