The document discusses a framework for revitalizing a business through brand reinvention. It provides examples of how companies like Olay, Cadillac, IBM, Walmart, and Apple successfully reinvented their brands by redefining their propositions, targeting new customer segments, transforming their product offerings and production processes, and creating new distribution channels. The framework involves assessing a brand's flexibility, market potential, alignment with trends, revenue size, and strategic usefulness to determine if it is a candidate for reinvention. Reinventing a brand requires holistically changing the brand proposition, target customers, offerings, production, and channels in an inter-departmental effort to stay relevant and drive sustained growth.
