Open innovation is a strategic phenomenon that has arisen in corporate life since the beginning of the 21st century. The management of this process involves a communicative dimension that both management and communication scholarship have overlooked over the last twenty years. At the same time, communication management in open innovation processes enacts the strategic nature of the discipline and practice. However, there is scant knowledge and evidence to be found in this discipline, despite the fact that the topic itself calls for deeper exploration of mainly a relational and communicative phenomena. We argue for the promotion of a comprehensive research agenda that entails delving into the theoretical and empirical challenges of the strategic communication discipline in open innovation. Likewise, this article responds to the call for greater interdisciplinary research. Findings include six research gaps, the examination of nine research lines, as it relates to discussion of specific methods/methodologies which would fill those gaps. Moreover, the proposed research pathways map out a starting-point for the future of this growing field of inquiry while also positioning strategic communication as a catalyst discipline and practice that will help to foster open innovation management and research.
