In this paper, we conceptualize visual representations (e.g., sketches, CAD drawings, and prototypes) as „artifacts of knowing‟ serving the purposes to share, transform, and symbolize organizational knowledge. First, we propose a comprehensive definition of visual representations by integrating insights from the literature domains of knowledge management and organizational culture. Building on the reviewed literature, we then develop a conceptual framework that articulates the visualization process in terms of a cyclical pathway between the formats (e.g., from sketches to prototypes) and the functions (e.g., from knowledge sharing to knowledge symbolization) of visual representations. After suggesting managerial recommendations for the use of visual representations in organizational knowledge management, we conclude our paper by pointing out the limitations of the current literature, and by suggesting directions for future research on visual knowledge management.
