No one disputes that knowledge is the lifeblood of international organizations and especially specialized agencies of the United Nations. However, there has been little consensus on the best methods to share knowledge, leverage the extensive international expertise and make it available to the constituents and partners of these organizations. What is their strategy for managing knowledge? Do they have one? What impact does it have? What is the role of senior management in championing knowledge sharing in these international organizations? These are the questions this paper addresses through the lenses of the evaluations of current knowledge sharing practices in two institutions located in Geneva, Switzerland, both part of the United Nations system.
