Funnily enough, Enron had the same system where if you scored towards the bottom you were quickly shown the door. http://www.time.com/time/business/article/0,8599,129988,00.h...

Of course, most big companies have a employing rating system, but Enron was different because 10-15 % people were asked to leave every year.

I'm pretty skeptical of the idea that harshly competitive environments have their value systems straight, but it bears mentioning that at Enron traders and deal makers were on the evaluation boards for the risk assessment group.

Absolutely correct. Much of their demise can be traced back to their refusal to provide their risk control group any teeth.
