Additionally, it is a misuse of the 80/20 rule to interpret a small number of categories or observations.This is a special case of the wider phenomenon of Pareto distributions.Using talent as an example, he and other researchers state, “The maximum success never coincides with the maximum talent, and vice-versa.”, and that such factors are the result of chance.It was also discovered that in general the 80% of a certain piece of software can be written in 20% of the total allocated time.It is the basis for the Pareto chart, one of the key tools used in total quality control and Six Sigma techniques.The Pareto principle serves as a baseline for ABC-analysis and XYZ-analysis, widely used in logistics and procurement for the purpose of optimizing stock of goods, as well as costs of keeping and replenishing that stock.This is broadly in line with the world population/wealth table above, where the bottom 60% of the people own 5.5% of the wealth, approximating to a 64/4 connection.The 64/4 correlation also implies a 32% 'fair' area between the 4% and 64%, where the lower 80% of the top 20% (16%) and upper 20% of the bottom 80% (also 16%) relates to the corresponding lower top and upper bottom of effects (32%).
In baseball, the Pareto principle has been perceived in Wins Above Replacement (an attempt to combine multiple statistics to determine a player's overall importance to a team).
Conversely, the hardest 20% of the code takes 80% of the time.
This factor is usually a part of COCOMO estimating for software coding.
It is an axiom of business management that "80% of sales come from 20% of clients".
Mathematically, the 80/20 rule is roughly followed by a power law distribution (also known as a Pareto distribution) for a particular set of parameters, and many natural phenomena have been shown empirically to exhibit such a distribution.
