Vilfredo Pareto received his doctorate after defending his dissertation on the principles of equilibrium of solids. This scientific work demonstrated the scientist's desire to seriously study the issues of social balance in society.
In 1887, he popularly presented all the conclusions that were made according to the 20/80 principle. A number of scientific publications appeared in print, where a new path of sociological research was shown. At that time, Wilfredo failed to prove the value and universality of his discovery in scientific circles. Therefore mexico phone lookup the materials he collected did not gain popularity among his contemporaries, and the 80 to 20 rule (the Pareto principle) was used for a long time only by a narrow circle of ideologists.
The history of the Pareto principle
Later, in 1949, the linguist J. Zipf from the USA made the same conclusions in his research: only 20% of labor costs will give no more than 80% of the potentially achievable indicators. As we can see, he interpreted the Pareto principle (or rather, its essence), already known to society, in his own way.
American business expert Joe Juran, who was involved in quality management in 1951, saw this rule in scientific publications and showed serious interest in it. After comparing this concept with his own developments, he was convinced of its viability, then registered the Pareto law under the name of its creator.
In his articles, Joseph wrote that this rule is universal and can be applied in different spheres of life. As proof, the scientist applied it in production and created an effective system for reducing defects in manufactured products. But Joe did not limit himself to this. Later, he analyzed other industries, using the Pareto principle in different spheres of life.
