The most innovative organizations are those that respond to and generate technological change by acting as effective learning systems. They reach high levels of innovation when structured to take advantage of the social, distributed, participative, situated learning processes developed by their members. The design of efficient learning organizations requires cognitive, technological, and social analysis. This volume in the NATO Special Programme on Advanced Educational Technology is about that analysis. The contributions focus on different key concepts, including community of practice, cooperation, and learning strategies in organizations. The book is not a comprehensive report on the field but it will substantially enhance the understanding of organizational learning and technology.
