The Pareto principle states that for many outcomes, roughly 80% of consequences come from 20% of causes (the "vital few").1(https://en.wikipedia.org/wiki/Pareto_principle#cite_note-NYT-1) Other names for this principle are the 80/20 rule, the law of the vital few, or the **principle of factor sparsity.**2(https://en.wikipedia.org/wiki/Pareto_principle#cite_note-2)3(https://en.wikipedia.org/wiki/Pareto_principle#cite_note-:0-3) ([View Highlight] (https://read.readwise.io/read/01h717xw80y33fwj3n20af4e8k))

In computing
In computer science the Pareto principle can be applied to optimization efforts.14(https://en.wikipedia.org/wiki/Pareto_principle#cite_note-optimization-14) For example, Microsoft noted that by fixing the top 20% of the most-reported bugs, 80% of the related errors and crashes in a given system would be eliminated.15(https://en.wikipedia.org/wiki/Pareto_principle#cite_note-15) Lowell Arthur expressed that "20% of the code has 80% of the errors. Find them, fix them!"16(https://en.wikipedia.org/wiki/Pareto_principle#cite_note-16) It was also discovered that, in general, 80% of a piece of software can be written in 20% of the total allocated time. Conversely, the hardest 20% of the code takes 80% of the time. This factor is usually a part of COCOMO estimating for software coding.
