In Scott Adams' book How to Win at Almost Everything and Still Win Big he describes a CEO who Scott met on a plane. The CEOs system was:
I've always thought about doing the following but never actually did. At my company the grade people on three different scores. Exceeds expectations, meets expectations, below expectations. They also grade on a curve, so if you have eight people working for you, 50% get meets expectation and 25% get exceeds and the other 25% get below expectations. Now if you're being measured against your co-workers, you should think twice before helping them as if you help them you reduce your odds of getting an exceeds expectations.
