Jim Stengel, Cait Lamberton, and Ken Favaro discuss the need to move beyond the 'brand vs. performance' debate in marketing. They emphasize the importance of providing value to consumers, measuring brand equity, and optimizing resource allocation using data and metrics. They introduce the FRMU model and discuss the emotional relationship consumers have with brands. The chapter also highlights the influence of the Barbie movie on Mattel's brand and stock price, and the relationship between performance marketing and brand.
