Knowledge is frag mented, som etimes difficult to locate and therefore to i mprove or to share. There is a need therefore to develop decision support ystems to im prove, store, share and capture data, information and knowledge. Decision support ystems is enable the transfo rmation of tacit to im plicit knowle dge to be shared and improved for decision making. They will also enable the conversion of explicit to implicit knowledge a process of internalisation.
