What is a community of practice?
A community of practice (CoP) is, according to cognitive anthropologists Jean Lave and Etienne Wenger, a group of people who share a craft and/or a profession. The group can evolve naturally because of the members' common interest in a particular domain or area, or it can be created specifically with the goal of gaining knowledge related to their field. It is through the process of sharing information and experiences with the group that the members learn from each other, and have an opportunity to develop themselves personally and professionally.
