See your brands through your customers' eyes.

Subaru markets an L.L. Bean Outback station wagon. Dell stamps Microsoft and Intel logos on its computers. Such inter-weaving of different companies' brands is now commonplace. But one of the central tools of brand management-portfolio mapping--has not kept pace with changes in the marketplace. Most conventional brand maps include only those brands owned by a company, arranged along organizational lines with little regard for how the brands influence customer perceptions. In this article, the authors present a new mapping tool--the brand portfolio molecule--that reveals the way brands appear to customers. The brand portfolio molecule includes all the brands that factor into a consumer's decision to buy, whether or not the company owns them. The first step in creating a brand portfolio molecule is to determine which brands should or should not be included. The second step is to classify each brand by asking five key questions: 1) How important is this brand to customers' purchase decisions about the brand you're mapping? 2) Is its influence positive or negative? 3) What market position does this brand occupy relative to the other brands in the portfolio? 4) How does this brand connect to the other brands in the portfolio? 5) How much control do you have over this brand? The last step is to map the molecule using a 3-D modeling program or by hand with pen and paper. Individual brands take the form of atoms, and they're clustered in ways that reflect how customers see them. The usefulness of the tool lies in its ability to show the many forces that influence a customer's buying decision--and to provide a powerful new way to think about brand strategy.
