Approaches to Knowledge Management
Hybrid approaches to knowledge management
The practice approach is used so that a repository stores only explicit knowledge that is relatively easy to document
Tacit knowledge initially stored in the repository is contact information about experts and their areas of expertise
Increasing the amount of tacit knowledge over time eventually leads to the attainment of a true process approach
