This chapter concentrates on knowledge-flow visualization and analysis in the for-profit business sector. We look first at an advanced-technology company involved with new-product development. The discussion turns then to examine an independent production company involved with a feature film. The third case involves a technology-transfer project between a university and a microelectronics company. In each case, we draw from secondary data sources for background. This should prove helpful to the reader who is interested in following up to consider more details than presented in this volume. We draw also from our own research and professional experience to fill in missing information, and we apply principles and techniques of this book to contribute new insights through examination of knowledge flows in the cases. Each application case concludes with exercises to stimulate critical thought, learning, and discussion.
