IBM discusses the evolution of knowledge management (KM) from KM 1.0 to KM 2.0. KM 1.0 focused on private controlled environments while KM 2.0 emphasizes public dynamic collaboration. Key aspects of the evolution include moving from individual work to immersion in workplace conversations, from static protected content to fluid participatory development of content, and from measuring value based on deliverables to also including online reputation. Innovation now occurs at the intersection of insights through mobilizing collective knowledge across traditional boundaries.
