Pareto Principle in software testing

Posted by:

In 1906 Vilfredo Pareto discovered the rule stating that in case of many events, roughly 80% of the effects come from 20% of the causes. Today, after more than 100 years, “Rule 80/20″ because it operates under that name, is still used to diagnose social, economic and many other phenomena, for example:

- 20 % of drivers cause 80 % of accidents
- 80% of sales come from 20% of clients
- we wear 20% of clothes for 80 % of the time

This rule has also use in software testing.
