A Community of Practice (CoP) is a group of people who share a common interest and work together to improve their knowledge and skills through ongoing interaction and information sharing. Key elements of a CoP include a shared domain of interest, a community of people who interact and learn from each other, and a focus on sharing practices to improve work. CoPs can exist within or between organizations and can operate at local or national levels. They evolve over time through real work, problem solving, learning, and innovation.
