Marketing success through differentiationof anything
Any product oi service can he differentiated, even the commodity that seems to differ from competitors' offerings only in price
On television we see product differentiation all the time, whether the subject of the commercial is a distinguishable good like an automobile or an indistinguishable good like laundry detergent. These are packaged products. How does the marketer differentiate a so-called commodity like isopropyl alcohol, strip steel, commercial bank services, or even legal counsel? The author describes the attributes of products that give the marketer opportunity to win the customer from the competition and, having won him, to keep him. Finally, the author describes the alert, imaginative state of mind that characterizes good management of product differentiation. "The way in which the manager operates becomes an extension of product differentiation," he says. Mr. Levitt is the Edward W.

There is no such thing as a commodity. All goods and services are diflferentiable. Though the usual presumption is that this is more true of consumer goods than of industrial goods and services, the opposite is the actual case. In the marketplace, differentiation is everywhere. Everybody-producer, fabricator, seller, broker, agent, merchant—tries constantly to distinguish his offering from all others. This is true even of those who produce and deal in primary metals, grains, chemicals, plastics, and money. Fabricators of consumer and industrial goods seek competitive distinction via product features—some visually or measurably identifiable, some cosmetically implied, and some rhetorically claimed by reference to real or suggested hidden attributes that promise results or values different from those of competitors' products. So too with consumer and industrial services— what I call, to be accurate, "intangibles." On the commodities exchanges, for example, dealers in metals, grains, and pork bellies trade in totally undifferentiated generic products. But what they "sell" is the claimed distinction of their execution—the efficiency of their transactions in thir clients' behalf, their responsiveness to inquiries, the clarity and speed of their confirmations, and the like. In short, the offered product is differentiated, though the generic product is identical. When the generic product is undifferentiated, the offered product makes the difference in getting customers and the delivered product in keeping them. When the knowledgeable senior partner of a wellknown Chicago brokerage firm appeared at a New York City bank in a tight-fitting, lime green polyester suit and Gucci shoes to solicit business in financial instrument futures, the outcome was predictably

poor. The unintended offering implied by his sartorial appearance contradicted the intended offering of his carefully prepared presentation. No wonder that Thomas Watson the elder insisted so uncompromisingly that his salesmen be attired in their famous IBM "uniforms." While clothes may not make the man, they may help make the sale. The usual presumption about so-called undifferentiated commodities is that they are exceedingly price sensitive. A fractionally lower price gets the business. That is seldom true except in the imagined world of economics textbooks. In the actual world of markets, nothing is exempt from other considerations, even when price competition rages. During periods of sustained surplus,...
