During the late 1930s I moved out of the field of quality control to become the corporate industrial engineer for Western Electric Company. As I moved into quality management posts in the late 1920s and the 1930s, I observed (as had many others before me) that a similar phenomenon existed with respect to employee absenteeism, causes of accidents, etc. It began in the mid-1920s when as a young engineer I observed (as had many others before me) that quality defects are unequal in frequency, i.e., when a long list of defects was arranged in the order of frequency, a relative few of the defects accounted for the bulk of the defectiveness. In addition, I have for some time felt an urge to narrate just how it came about that some early experiences in seemingly unrelated fields (quality control, cryptanalysis, industrial engineering, government administration, management research) nevertheless converged to misname the Pareto principle. My motive in offering the present paper is in part to minimize this tendency to embroider the work of a distinguished Italian economist. On various occasions contemporary authors, when referring to the Pareto principle, have fabricated some embellishments and otherwise attributed to Vilfredo Pareto additional things which he did not do. The matter has not stopped with my own error. Years ago I gave the name 'Pareto' to this principle of the 'vital few and trivial many.' On subsequent challenge, I was forced to confess that I had mistakenly applied the wrong nameДў PГЎgina 2 de 5 to the principle.1 This confession changed nothing the name 'Pareto principle' has continued in force, and seems destined to become a permanent label for the phenomenon.

It is a shorthand name for the phenomenon that in any population which contributes to a common effect, a relative few of the contributors account for the bulk of the effect. Juran Contributing Editor The 'Pareto principle' has by this time become deeply rooted in our industrial literature.
