The Pareto Distribution
Quite Simply...
20% of the input creates 80% of the result
Mathematical Formula
initially derived from Economics
Juan Juran applied Pareto's ideas to other fields and called the idea, the Pareto Principle.
Where It Came From?
Joseph Juran identified it in the 1940s and erroneously attributed it to Pareto after applying Pareto's ideas to other disciplines.
Juran noted that 20% of the unit was important and 80% were virtually irrelevant.
Manage This Issue
Juan Juarn identified that project managers and employees should focus 20% of their work will occupy them 80% of the time. The other 20% of the time they will be consumed with more minor tasks.
What Does It Mean?
Pareto's meaning:
Very few people in Italy held most of the country's wealth.
General meaning:
Juan Juran found that this can be applied to other areas. He identified the more concrete equation of 80/20 and attributed it to Pareto.
20% of causes
80% of effects
80%
20%
20% of the features cause 80% of the usage
20% of the bugs cause 80% of the crashes
20% of the customers create 80% of the revenue
20% of the workers produce 80% of the result
Do Not confuse with: 80+20=100
