The document discusses brand mantras and core brand values. It defines a brand mantra as a short 3-5 word phrase that captures the essence of a brand's positioning and values. Examples given are Nike's "Authentic Athletic Performance" and Disney's "Fun Family Entertainment". A good brand mantra has three components: an emotional component, descriptive modifier, and brand function. Core brand values characterize the most important dimensions of a brand's mental map and relate to its points of parity and difference compared to other brands. The brand mantra and core values guide a brand's products, communication, and ensure continuity.
