Research problem: Content strategy, whether narrowly focused on the production of web-based materials for customers or managing the data, information, and documentation of an entire enterprise, has become the latest in a series of movements and methods that have sought to improve the integration of professional and technical communication with the marketing, training, and business processes of organizations. Research questions: How is content strategy defined and described in professional and scholarly literature? What do these definitions and descriptions suggest about the direction of the field of professional and technical communication? Literature review: The theoretical foundation of this study is Classical Rhetorical theory which, for thousands of years, has provided critical methods and vocabularies for the analysis of discourse; my purpose in using it here is to rely on a consistent lens that has served professional and technical communicators well. Classical rhetorical principles can give us useful insight into content strategy, the latest in a series of movements that have captured the attention of professional and technical communicators because they have promised to expand the scope of the work and move the work from the fringes of organizational activity to the center. Previous movements include knowledge management, single sourcing, and content management. Methodology: Because content strategy is an emerging area, I conducted an integrative literature review to characterize this emerging field. This involved a systematic search of peer-reviewed and professional literature on content strategy that met specific qualifications, reading and collecting information from each source about its answers to the research question and its authorship, and analyzing those data to find patterns in them. Results and conclusions: Because only two peer-reviewed sources existed on content strategy, the majority of the literature reviewed emerged from the trade press. I survey the definitions of content and content strategy provided by this literature, and found that almost every definition uses content as part of the definition, leading to some lack of clarity in all of those definitions. But three areas of consensus exist among the definitions: that content strategy is: (a) more inclusive of the lifecycle of content (addressing the processes of creating, revising, approving, publishing, and revising material), (b) integrated with technical and business requirements, and (c) largely focused on material used by customers and, therefore, focused on marketing and support documents. It primarily focuses on traditional genres of content and overlooks emerging genres. The literature suggests that content strategy provides a pathway to make the work of technical communicators more central to organizations. But the literature offers only broad advice for doing so, with few examples (other than some specific templates, which primarily benefit those who already have experience with content strategy). The advice primarily comes from authors working in consulting firms and, as a result, might not reflect the challenges that professional and technical communicators who work internally experience.
