D. The Impact of Bosses:
How much do bosses matter? There are two notions of the impact of bosses. One is the increase in productivity that a typical worker would achieve by moving from a poor boss to a good boss.
The other is the increase in the productivity of all team members, resulting from more time with the Average boss.
If bosses were mere decorations, one would expect no variation in boss effects beyond sampling error.
