Worth taking a look at pdf linked below, it's a research piece from Accenture covering how Marketers create and manage content.

The key takeaway for me is that it is difficult to create, manage and measure the impact of your content on a consistent basis because a coherent strategy involves almost everyone in an organisation. 

It's also interesting to read the responses to the question "What would put your organization on a path to success for content management and production?" The answers range from lack of a clear strategy to better integration of technology and tools. Not one of the 13 answers has been given by more than 10% of the respondants - showing that everyone is struggling with content, but in a different way!
