The document discusses the role of project management offices (PMOs) in facilitating knowledge management within organizations. It outlines six aspects of effective knowledge management: 1) having a social dimension that connects people, 2) focusing on knowledge flows between people rather than static knowledge stocks, 3) demonstrating how knowledge management makes a difference, 4) enabling improvement and learning, 5) cultivating a knowledge-sharing culture, and 6) recognizing the importance of knowledge management. The document argues that PMOs should consider how to embed these aspects of knowledge management into their activities and address potential obstacles to sharing knowledge within projects and programs.
