Similarly, a firm that finds that 80 percent of its profits come from 20 percent of its customers should use this information to concentrate on keeping that 20 percent happy and increasing the business carried out with them. This is much easier, as well as more rewarding, than paying equal attention to the whole customer group. Or, if the firm finds that 80 percent of its profits come from 20 percent of its products, it should put most of its efforts behind selling more of those products.
