This document discusses achieving competitive advantage through superior customer experience. It shows that companies with best customer experience ("CX Leaders") significantly outperformed "CX Laggards" and the S&P 500 in stock performance between 2007-2012, with Leaders outperforming Laggards by 77%. However, only 8% of customers actually agree they receive superior experience, despite 80% of companies believing they provide it. To win, companies must use data insights to customize experiences, operationalize empathy through processes, and have courage to innovate and challenge norms. Following this "yellow brick road" of brains, heart, and courage leads to customer experience success.
