Although the importance of the two aspects of knowledge
management is now well-recognized by many organizations, the full potential of
knowledge management still remains to be realized. In fact not all organizations
with some form of knowledge management systems in place are aware that
they have such systems. Most organizations have some kind of system for the
management of explicit knowledge, whether simple or complex. However, they
may not necessarily call it a knowledge management system. On the other hand,
the management of tacit knowledge is not common and the current technology-
based knowledge management has not developed a fully effective means for
the extraction of tacit knowledge. Although tacit knowledge is at the core of
organizational knowledge, it is so personal in nature that it is difficult to formalize
and communicate.
