Peppers and Rogers wrote a pioneering work on reaching customers, that taught marketers to look beyond "segments" to the individual people who actually bought their products or services. But they make an essential mistake in confusing the customer's familiarity with a particular business with having a relationship. Relationships exist between people who know one another, and a business relationship is one in which the customer deals with the same provider for each transaction. An example is a personal trainer you go to each time you work out, or a using the same accountant (not just the same accounting firm) for many years at tax time, or going to the same hairstylist, even following her when she moves to a new salon. These are real relationships, but phoning a catalog company and talking to a different person each time, even if that person can check your past orders and already has the billing information, is NOT a relationship.
Using technology to make a transaction more efficient can be a service to customers. People do not always seek a relationship with their provider; sometimes they want anonymity, and the idea that the provider organization "knows" all about them can be scary. Only by distinguishing between real relationships and the kind of "pseudo-relationship" that Peppers and Rogers advocate can you sort out these issues.
To learn more about the concept of "relationship" versus the more common service encounter (between customer and provider who do not know each other and do not expect to interact again), read The Brave New Service Strategy by Dr. Barbara A. Gutek and Theresa Welsh. They postulate a service model that consists of a triangle of Customer, Organization and Provider (COP).
