From Rich Karlgaard‘s latest column in Forbes magazine:
Bill Gates once said that a great programmer is worth ten thousand times the price of a good programmer. Such extreme talent may or may not be relevant to your company. What matters to every company is talent evolution versus talent deterioration. Multiply 1.01 times a large number and watch it grow. Conversely, multiply 0.99 times a large number and watch it shrink. Now think of your employee base: Is it getting better or worse?
I think there’s more luck involved in success than just finding good talent, but I do think good talent can improve the odds.
