Knowledge is a broad and abstract notion that has defined epistemological debate in western philosophy since the classical Greek era. In the past few years, however, there has been a raging interest in treating knowledge as a significant organizational resource. The heightened interest in organizational knowledge and knowledge management stems from the transition into the knowledge economy, where knowledge is viewed as the principle source of value creation and sustainable competitive advantage. Consistent with the growing interest in organizational knowledge and knowledge management (KM), recently IS researchers have been promoting a class of information systems, referred to as knowledge management systems (KMS). The objective of KMS is to support construction, sharing and application of knowledge in organizations. Knowledge and knowledge management are complex and multi-faceted concepts. Thus, effective development and implementation of KMS requires a foundation in several rich literatures.
