As nonprofit organizations grow, managing knowledge in the ad hoc ways that worked when they were smaller often does not translate into future success at a larger scale. New, more systematic approaches to capturing, sharing, and applying knowledge are needed. While there are no silver bullet solutions for the challenges of knowledge management in large and growing nonprofits, a number of organizations are experimenting successfully with new approaches that may prove instructive to their peers. To shine some light on the range of strategies now being used, Knowing Is Not Enough offers a framework for helping nonprofits and foundations to think about how they capture, organize, and share knowledge, and provides a sampling of the knowledge management tools, options, and approaches that are now available.
