A number of social, economic, technological, and scientific trends have led to the emergence of communities of practice centered on the notion of the knowledge-based organization. However, the scientific foundation (knowledge elicitation methodology) and the commercial growth of knowledge management (KM) have largely developed in parallel. So, the creation of human-centered systems faces lingering challenges. In the KM process, company management establishes a program whereby experts who possess valuable knowledge collaborate with a knowledge engineer. Working together, they elicit the expert's wisdom for inclusion in the organization's knowledge base.
