The challenges and complexities of the modem
marketplace make efficient and effective marketing an
imperative. The concept ofbrand equity has been put forth as
means to focus marketing efforts. A product or service with
no brand equity that finds itself in competition with high

feel like to be a eunuch. Marketers of successful
twenty-first-century brands will continually evolve and
adapt every aspect of their marketing programs to enhance
brand equity. This paper provides a different way of looking

ability-based brand equity are bound together inextricably.

The brand equity you are contemplating, developing, or
maintaining must be nurtured and cared about. It must be
cultivated, nourished, and defended.
