Knowledge is becoming a critical success factor for organizational performance. Organizations not only should learn but also learn faster to survive, and remain successful. Like any other management initiative, implementing knowledge management in organizations is an investment decision and thus, its outcomes must be defined and measured. To measure success or lack of it, an organization has to develop metrics and benchmarks based on the knowledge management criteria. This book describes a research effort that is a non-experimental, exploratory research to establish criteria for measuring knowledge management efforts. The research helped to establish knowledge management criteria for government, non-profit and for-profit organizations. This book is expected to support government, non- profit, and for-profit organizations in making decisions about knowledge management initiatives and measuring their knowledge management efforts.
