Knowledge Management (KM) is a relatively new area that has been evolving at an astonishing pace since mid-1990 as organizations increasingly recognize the importance of developing an internal environment where the knowledge is effectively managed. As in other technical fields, space operations face the challenge of preserving and sharing knowledge. At the Directorate of Operations and Infrastructure (D/OPS), KM is considered a strategic issue for maintaining and strengthening the leadership in spacecraft operations and ground systems infrastructure in an expanding international context.
