App Covey defines effectiveness as the balance of obtaining desirable results with caring for that which produces those results. He illustrates this by referring to the fable of the goose that laid the golden eggs. He further claims that effectiveness can be expressed in terms of the P/PC ratio, where P refers to getting desired results and PC is caring for that which produces the results.
