The Origin.

起源。

The 80-20 Rule, also known as the Pareto Principle, originated from the observations of Vilfredo Pareto, an Italian economist who lived in the late 19th and early 20th centuries.

80-20 法則又稱帕累託原則，源於 19 世紀末 20 世紀初意大利經濟學家維爾弗雷多-帕累託的觀察。

Pareto noticed a pattern in the distribution of wealth in Italy, where approximately 80% of the land was owned by 20% of the population.

帕累託注意到意大利財富分配的一種模式，即大約 80% 的土地被 20% 的人口所擁有。

This principle was later popularized and generalized by Joseph M.

這一原則後來被約瑟夫-M.

Huron, a Romanian-born American engineer.

休倫，羅馬尼亞出生的美國工程師。

He used the principle as a tool for quality control, suggesting that 80% of the problems in any process are usually caused by 20% of the possible defects.

他將這一原則作為品質控制的工具，認為任何流程中 80% 的問題通常是由 20% 的可能缺陷造成的。

Over time, the 80-20 Rule has been applied to a wide range of fields beyond economics and quality control, including sales, marketing, personal productivity, and more.

隨著時間的推移，80-20 法則已被廣泛應用於經濟學和品質控制以外的領域，包括銷售、市場營銷、個人生產力等。
