We are certain that the ultimate measure of influence is not about the spotlight but a CMO’s commercial impact on the business and brands they help steward, and the marketing community globally. We are certain the most effective exercise of a CMO’s influence lies in their ability to change the attitudes and behaviors of others—the “consumers” and “customers” they court externally and, as surely, their C-suite colleagues and teams internally.
