"The business of America," in the unforgettable words of our 30th President, "is business." Mr. Drucker has a penchant for comparable profundities. This is still another of his "what to do" books and for it he claims the distinction of being "the first attempt at an organized presentation of the economic tasks of the business executive." It also has a practical rather than theoretical thesis: "Economic performance... is the specific function and contribution of business enterprise, and the reason for its existence." Getting down to cases and drawing from his experience as a consultant, he explains how to understand "Business Realities" -- how to "Focus on Opportunity" -- and what is required of a successful "Program for Performance." You still don't know "what to do"? Well, get out there and manage! Bring "order out of chaos." Help society to "truly accept that business is a rational pursuit." And, yes, while you're at it -- make some money.
