Pareto 80 20 rule: 12 examples, tips and ideas (2024)

Vilfredo de Pareto was an Italian sociologist and economist who, during his studies, realized that, in general, 80% of a nation’s income was in the hands of only 20% of the population.

Extrapolating this concept, Pareto defined a rule that became known as the Pareto 80 20 rule, which could be summarized as follows:
80% of results are produced by 20% of causes.

So, here are some Pareto 80 20 rule examples:

  • 20% of criminals commit 80% of crimes
  • 20% of drivers cause 80% of all traffic accidents
  • 80% of pollution originates from 20% of all factories
  • 20% of a companies products represent 80% of sales
  • 20% of employees are responsible for 80% of the results
  • 20% of students have grades 80% or higher

And so on….

But why does it matter?

You can use the Pareto law in business, process management, quality control, medicine and many other areas.

Think of it this way: Under this rule, 20% of your customers are responsible for 80% of your revenue. Would it not be interesting to use CRM concepts to find out who these 20% are and invest more in them?

There are other Pareto 80 20 rule examples, such as these, which we will discuss in this post.

Pareto 80 20 Rule Examples: How to use them in your business

A phrase reminiscent of Pareto’s law was enunciated by the 34th American President, Dwight D. Eisenhower:

“What is important is rarely urgent, what is urgent is rarely important.”

Like Pareto’s law, this phrase helps determine which tasks are most important and which you should attack first, a concept that spawned the famous Eisenhower Matrix.

So if something is urgent and important (very rare) do it first, if it is only urgent or only important, delegate it to someone, and if it is neither, forget it!

Likewise, the Pareto 80 20 rule helps managers focus on what is most important and urgent.

Here are a few more examples of the Pareto 80 20 rule and how you can apply it in your company.

20% of the marketing efforts represent 80% of the results

These Pareto 80 20 rule examples are critical for anyone who wants to achieve maximum results with less marketing effort.

The problem is that marketing and communication actions are difficult to measure.

Imagine that you launch a television advertising campaign and your products sell very well. But at the same time, there was an incredible improvement in the economy and, as well, one of your direct competitors had logistics problems and couldn’t deliver their products to the stores.

So, how would you know if your campaign was effective?
This is a dilemma that the Pareto 80 20 rule is not going to resolve. There needs to be Research on Recall and other studies to determine this issue.

Hence, why many marketers have opted for online marketing, which can measure results with much more effectiveness and assertiveness, which helps a lot in decision making.
