The document summarizes the evolution of the relationship between data, creativity, and strategy in advertising agencies. Originally the three worked closely together (the band), but they became separated (the break-up) as data, creativity, and strategy flourished independently. By 2012, it was recognized that in the modern connected world they needed to work together again (get the band back together). The document provides examples of how integrating data, creativity, and strategy led to more effective campaigns. It concludes by outlining the key elements needed to build the new integrated model, including shared measures and a cohesive structure.
