The document discusses strategies for using brand equity to drive sustainable growth. It defines brand equity as the perceived value of a brand's image attributes. It then presents the Brand Value Equation, which calculates brand value based on product/service benefits, channel benefits, brand equity, and costs. The equation shows that brand equity is a powerful lever for competitive advantage. However, brands face threats of losing relevance, so strategies like branded sponsorships and social programs are needed to create energy and remain relevant. Crucially, internal brand-building must establish a brand's promise and values before external initiatives. Research shows "storydoing" companies that live their brand story outperform those only telling it.
