Functional Requirement Analysis is an integral part of the top-down process of translating system-level requirements into detailed functional and performance design criteria. Our goal in TAXAPA is to learn, test, or adapt existing principles to improve our skills and offer our customers the best outcomes.
There is a great principle, which we use to understand which functional variables have the highest cumulative effects on the application’s usage.
The Pareto principle, also knows as the “80-20 rule,” says that, for many events, approximately 80% of the effects come from 20% of the causes.
Mr. Vilfredo Pareto (1848-1923) was a genial Italian engineer and sociologist who observed 80% of the land in Italy was owned by 20% of the population. Later, the same phenomena (“80-20 rule”) were detected in different spheres of the everyday world.
We in TAXAPA become enthusiasts of the 80/20 rule. We developed a part of our methodology on it, and it works immensely. We apply Pareto Charts and procedures mainly in requirements analysis, and it helps our customers visualize what matters most.
