Ask HN: What's been your experience with performance reviews?
Wondering if anyone has had good experiences with performance reviews? What's the biggest pain about them?
He has a series of videos worth their weight in gold. One video is related.
Take a bucket with 50% black marbles and 50% white marbles. Give each employee a paddle that has 25 holes arranged so they can dip the paddle into the bucket and withdraw 25 random marbles. Each time they withdraw the paddle, count the marbles and add the number of black marbles to the persons score.
After a while do a "performance review". Give a raise to the person with the highest number of black marbles. Fire the person with the least number of black marbles.
The point is rather obvious and I won't insult you with an analysis.
Managers who depend on performance reviews are simply unqualified to manage.
