Define Knowledge management?

Knowledge Management (Knowledge Management in English) is a multidisciplinary managerial approach which includes all initiatives, methods and techniques to collect, identify, analyze, organize, store, share knowledge of an organization's members - knowledge created by the company itself (marketing, research and development) or acquired externally (competitive intelligence) - to achieve a goal.

Knowledge management (KM) therefore implies a strong tie to organizational goals and strategy, and it involves the management of knowledge that is useful for some purpose and which creates value for the organization.

Knowledge Management is "knowing what you know" and how you can effectively apply it at the right time and place to achieve the desired positive results. 

In humans it can be called as self realization, what an individual is capable of doing through his knowledge. In case of organisations the above para can be considered.
