The document summarizes the key findings of IBM's 2011 Global CMO Study, which involved interviews with over 1,700 CMOs from around the world. The study found that CMOs see four main challenges facing marketing: the explosion of data, social media, proliferation of new channels and devices, and shifting demographics. However, CMOs from high-performing companies address these challenges differently than others by focusing on customer intimacy, mining new digital data sources, and fostering relationships over just transactions. They also aim to develop a clear corporate character for their organization.
