The 80/20 Rule states that, in any particular domain, a small number of things account for the majority of the results. For example, 80 percent of the land in Italy is owned by 20 percent of the people. Or, 75 percent of NBA championships are won by 20 percent of the teams. The numbers don't have to add up to 100.

For example, business owners may discover the majority of revenue comes from a handful of important clients. The 80/20 Rule would recommend that the most effective course of action would be to focus exclusively on serving these clients (and on finding others like them) and either stop serving others or let the majority
