Inimeste hindamine on loterii


A common fallacy is the supposition that it is possible to rate people; to put them in rank order or performance… The performance of anybody is the result of many forces – the person himself, the people that he works with, the job… his customer, his management…

These forces will produce unbelievably large differences between people. In fact, as we shall see, apparent differences between people arise almost entirely from action of the system that they work in, not from the people themselves. A man not promoted is unable to understand why his performance is lower than someone else’s. No wonder; his rating was the result of a lottery.

William Edwards Deming, Out of the Crisis (originally published in 1982)
