This chapter concentrates on knowledge-flow visualization and analysis in the public sector. We look first at a military organization involved with maritime warfare. The discussion turns then to examine a federal government agency involved with a knowledge management program. The third case examines a public service organization involved with large-scale IT integration. 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 also draw 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.
