This document discusses building strong brands. It defines brand equity as a set of assets and liabilities linked to a brand's name that can add or subtract value for customers. Building strong brands is challenging due to price competition, innovation from others, and short-term pressures. The brand identity provides purpose and meaning for the brand and helps establish relationships with customers. Strong identities avoid traps like focusing only on image or specific attributes. A brand identity can be viewed as a product, organization, person, or symbol. McDonald's brand focuses on value and serving many customers, while Nike's brand centers on sports performance and an exciting personality. Both provide functional, emotional, and self-expressive value to customers.
