and results in a continuum of expertise within a community of practice where some members participate more and others less actively and frequently. Wenger et al. (2002) assert that a CoP usually consists of a rather small core group, which
actively participates in community interactions and assumes community leadership, usually the community experts and managers, a small active group consisting of members who participate quite frequently, but not as regularly as the core group members, and a large portion of community members who rarely participate (such members are called peripheral
participants).
