This paper outlines how case-based reasoning technology may satisfy certain outstanding requirements in the field of knowledge management (KM). The innovative handling tacit and cultural knowledge is a key factor that will define the future success of commercial organisations. The growing recognition that KM is principally people focused should give rise to a technological infrastructure capable of supporting this requirement. Case-based reasoning is ideally placed to handle the storage, indexing and retrieval of both tacit and cultural knowledge. A case study is described that deals with the production and deployment of a case-based reasoning system for the British Airways Concorde Olympus powerplant. The system makes available the collective past experiences of Concorde engineering staff to assist in problem solving.
