Knowledge management involves systematically collecting, structuring, and distributing knowledge across an organization to support decision-making and improve competitive advantage. There are two types of knowledge - explicit knowledge which is expressed formally, and tacit knowledge which is harder to express. Knowledge resides in structured information, unstructured information, and expertise within an organization. The purpose of knowledge management is to harness knowledge resources to help an organization learn, adapt, and deliver value. Effective knowledge management involves generating, accessing, using, and transferring knowledge through appropriate strategies, technologies, and cultural elements. In the future, knowledge management will be important for organizations to gain strategic insights, overcome challenges, and build long-term relationships and productivity.
