Think about your closet for a moment - how many of your clothes do you wear often? You may notice that you wear about 20% of your clothes 80% of the time. This idea of a small proportion making up a significant part is called the Pareto Principle, also known as the 80/20 rule.
It's named after an Italian economist, Vilfredo Pareto, who in the 1900s, observed that 80% of Italy's land was owned by 20% of the population. He also noticed that in his garden, 20% of the pea pods produced 80% of the peas. Surprisingly, this kind of uneven distribution applies in many areas beyond gardening and economics.
The Pareto Principle isn't a law of nature, but a pattern that often shows up in different areas. In business, it often happens that 80% of a company's revenue comes from 20% of its customers. In software, 20% of the bugs may cause 80% of the crashes.
However, it's important to understand this '80/20' distribution is not about precision. It could easily be '90/10' or '70/30', depending on the specific scenario. The point is that a small proportion often makes up a significant outcome, whether it's wealth distribution, productivity, sales, or even health issues.
So, should we only then focus on the 20%? Not necessarily, because it depends on your goals and context. If you’re a business person, identifying that key 20% could mean more profits with less effort. It helps to prioritize tasks, customers, or goals that truly matter. But it doesn’t mean that the remainder 80% is irrelevant, it might still be necessary, just with less impact.
In conclusion, the Pareto Principle is a handy tool to understand the world better and to help focus our effort and resources. It reminds us that inequality of outcomes is not necessarily a flaw, but often a feature of our complex world. Just like you have those favorite clothes you wear most of the time, you might have those highly productive tasks, loyal customers, or great friends who provide most of your positive results and happiness.
