The 80/20 Rule
The Pareto principle (also known as the 80-20 rule) states that, for many events, roughly 80% of the effects come from 20% of the causes.
In other words, 20% of the effort/investment leads to 80% of the results. For example:
- 20% of the people do 80% of the work;
- 20% of your activities generate 80% of your results;
- 20% of your clients generate 80% of your revenues.
If we assume that this rule applies to the time, energy and resources we invest in our businesses and our marketing communication efforts, we should think through its implications.
