Forrester and Heidrick & Struggles fielded a global survey of 275 CMOs in Q4 2015 to better understand the role's evolution and the keys for future success. Collaborating closely with John M. Abele, managing partner of Heidrick & Struggles' Marketing, Sales & Strategy Officers Practice, we learned that CMOs must now articulate exactly how marketing creates business value and master an increasingly broad skillset. Evolved CMOs who are committed to understanding customers and to driving that philosophy throughout the organization are those who will take charge in the C-suite.
