““But recognizing changes in public taste and then reacting promptly to these changes is not enough. As has been said before, in the business world customers simply do not beat a path to the door of the man with the better mousetrap. In the competitive world of commerce it is vital to make the potential customer aware of the advantages of a product or service. This awareness can be created only by understanding what the potential buyer really wants (sometimes when the customer himself doesn’t clearly recognize why these advantages appeal to him) and explaining it to him not in the seller’s terms but in his terms.””
