Money, security and trust are intimately connected. So it is with knowledge. We treat knowledge and money in similar ways. We give trivial knowledge away without much thought, much like one might choose to spend small change. We will invest our most important know-how carefully, in a trusted relationship, as we would our life savings. Knowledge will not be shared openly by everyone; a choice to share knowledge is an investment decision by the source.
A knowledge management system, either as a business process, a technology, or both, will fail unless this aspect of knowledge is taken to heart. The system must act as a trusted investment vehicle appropriate to the value of the knowledge, or it will suffer from a lack of market players.
