In “Fusing Content Strategy with Design”, David Gillis gives a very good summary of content strategy and its interplay with the overall user experience strategy and information architecture. The leading advocate for the field, Kristina Halvorson defines the field as such:
Content strategy plans for the creation, publication, and governance of useful, usable content.
Necessarily, the content strategist must work to define not only which content will be published, but why we’re publishing it in the first place.
I particularly like the way he discusses the importance of setting contexts, using context maps, to better integrate content with the overall experience (see example map below).
Such discussions all point to the importance of a fully integrated product experience process where content certainly plays a very big (and often overlooked) role.
