Abstract- This paper presents the results from a multiplecase study of knowledge management systems (KM -systems) in practical use. A set of general problem areas concerning the investigated KM -systems has been identified. These problem areas constitute the starting point of the discussion regarding design implications of KM -systems. One conclusion is that significant functions are missing in the KM -systems. Most of them can be described as traditional personnel administration systems, complemented with features that file competencies. A final conclusion is that the KM -systems' functions have to be developed and improved, if the organizations' KM-efforts shall `survive'.
