This document discusses the past, present, and future of knowledge management (KM). It describes how KM has evolved from informal storytelling to more formal and structured approaches, and is now becoming more social and collaborative through tools like Enterprise 2.0. The future of KM is presented as integrating data, documents, and technologies to support a balance between centralized governance and decentralized sharing. Organizations will provide resources like vocabularies and taxonomies to support personalized, collaborative innovation, better decision making, and operational knowledge through a transparent KM platform.
