<P> Shainin 's development of the `` Red X '' concept originated from his association with Joseph Juran . In the 1940s Juran coined and popularized the notion of `` the vital few and trivial many , '' also known as `` The Pareto Principle , '' recognizing the uneven impact of problems on business performance to be the same phenomenon that Vilfredo Pareto had observed in respect to the distribution of wealth . As suggested by Juran , `` 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 .
