The Pareto Principle, also known as the 80-20 Rule, is a widely observed phenomenon stating that roughly 80% of effects come from 20% of causes. It originated from Vilfredo Pareto's observation that approximately 80% of the land in Italy was owned by 20% of the population. This principle has been broadly applied across various fields such as business, economics, health, and productivity to identify vital few factors that generate the majority of results or benefits.
