KM is about making the right knowledge available to the right people. Knowledge management is systematically managing an organization's knowledge assets to create value and meet strategic goals through initiatives, processes, strategies, and systems that sustain and enhance storing, assessing, sharing, refining, and creating knowledge. Several management theorists have contributed to evaluating KM, including Peter Drucker in the 1970s recognizing information and knowledge as organizational resources and Peter Senge's concept of a "learning organization", as well as Chaparral Steel implementing a knowledge management strategy.
