Introduces the knowledge value chain model as a knowledge management (KM) framework. The model consists of knowledge infrastructure (knowledge worker recruitment, knowledge storage capacity, customer/supplier relationship and CKO and management), the process of KM (knowledge acquisition, knowledge innovation, knowledge protection, knowledge integration, and knowledge dissemination), and the interaction among those components resulting in knowledge performance. Further to the discussion of knowledge value chain (KVC), the following viewpoint was proposed: KM guides the way a corporation performs individual knowledge activities and organizes its entire KVC. It was suggested that competitive advantage grows out of the way corporations organize and perform discrete activities in knowledge value chain which should be measured by the core competence of corporation.
