This chapter concentrates on knowledge-flow diagnosis and intervention in the private, not-for-profit sector. We look first at a national youth soccer organization. The discussion turns then to examine a local tennis club. The final case examines a nondenominational community church. In each case, we draw in part from secondary data sources for the background. This should prove helpful to the reader who is interested in following up to consider more details than presented in this volume. Here we also draw considerably from our own research and personal 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.
