Anthropologist Jean Lave and computer scientist Etienne Wenger coined the term ‘communities of practice’, inspired by their model of 'situated learning'—in which learning is not an isolated activity, but a process of social engagement. They described communities of practice as groups of people who share a concern or a passion, and learn how to improve or extend their impact through interaction. Think groups of artists, human rights specialists, tennis players—people join together linked by any number of social or professional disciplines. In reciprocal communities built on trust, we flourish with a perpetual exchange of knowledge. No matter what the common passion, we grow personally and professionally by sharing what we know.
