“Pareto Principle” (also known as the “80/20 rule”) refers to the concept that a small proportion (e.g. 20%) of a group or population (e.g. customers, products, etc.) typically generates a disproportionate amount (e.g. 80%) of the outcomes (e.g. revenue, value, etc.). In product management, understanding and applying the Pareto Principle can be useful for identifying and prioritising opportunities or resources.
