80/20 rule

Imbalanced input-output ratio

The 80/20 rule is the observation that roughly 80 percent of outcomes come from 20 percent of causes.

Also called the Pareto principle, it appears across domains: 80 percent of sales come from 20 percent of customers, 80 percent of problems stem from 20 percent of causes.

The ratio is approximate—the insight is that inputs and outputs are rarely distributed evenly.

Focus on the 20 percent of tasks that produce 80 percent of your results.
