A Community of Practice (CoP) is an informal group that comes together around a common interest or need. There are several types of CoPs, including those focused on problem solving, knowledge sharing, best practices, and innovation. CoPs are self-organizing and non-hierarchical. They provide benefits like faster problem solving, knowledge sharing, and skill development. To establish a CoP, a facilitator identifies the business need and determines the value in addressing it through a CoP rather than other means. The facilitator then works to engage potential members and establish operating principles for the group.
