Knowledge management (KM) is the collection of methods relating to creating, sharing, using, and managing the knowledge and information of an organization. It refers to a multidisciplinary approach to achieving organizational objectives by making the best use of knowledge. An established discipline since 1991, KM includes courses taught in the fields of business administration, information systems, management, library, and information science.Other fields may contribute to KM research, including information and media, computer science, public health, and public policy. Several universities offer dedicated master's degrees in knowledge management. Many large companies, public institutions, and non-profit organizations have resources dedicated to internal KM efforts, often as a part of their business strategy, IT, or human resource management departments. Several consulting companies provide advice regarding KM to these organizations.[6]Knowledge management efforts typically focus on organizational objectives such as improved performance, competitive advantage, innovation, the sharing of lessons learned, integration, and continuous improvement of the organization.
