In a progressively knowledge-dependent economy, businesses need to pay greater attention to harnessing the knowledge that resides in their organizations. However, despite increasing investment in knowledge management (KM) tools, organizations often experience frustration in developing a knowledge sharing culture. This article describes how HP’s Decision Support and Analytics Services (referred to as HP Analytics) unit in India promoted initiatives aimed at changing the behavior of employees and successfully fostered a knowledge sharing culture as it implemented a cost-effective KM platform using web-based collaborative technologies. Its experiences in branding the KM program, establishing interest groups, using opinion leaders as KM ambassadors, and encouraging blogging over a multi-year period provide important lessons for CIOs and other organizational leaders who seek to build a knowledge sharing culture.
