Derek Price, who was a British physicist, historian of science, and information scientist, discovered ​the following (now called Price’s law):​ ​50% of the work is done by the square root of the total number of people who participate in the work.​

In every workplace, the relationship between value and people is asymmetric. Only a handful of people are responsible for the majority of the value creation. This is known as Price’s Law: Why Only A Few People Generate Half Of The Results?
