It’s no secret that in many industries today, upstream activities—such as sourcing, production, and logistics—are being commoditized or outsourced, while downstream activities aimed at reducing customers’ costs and risks are emerging as the drivers of value creation and sources of competitive advantage. Consider a consumer’s purchase of a can of Coca-Cola. In a supermarket or warehouse club the consumer buys the drink as part of a 24-pack. The price is about 25 cents a can. The same consumer, finding herself in a park on a hot summer day, gladly pays two dollars for a chilled can of Coke sold at the point-of-thirst through a vending machine. That 700% price premium is attributable not to a better or different product but to a more convenient means of obtaining it. What the customer values is this: not having to remember to buy the 24-pack in advance, break out one can and find a place to store the rest, lug the can around all day, and figure out how to keep it chilled until she’s thirsty.
