Communities of Practice are groups of professionals who share a common discipline, domain, or area of expertise and interact over time to exchange knowledge, solve problems, and strengthen organizational capability. In the CInP innovation-management context, this is not a formal department, not a center of excellence, and not a one-time ideation event. The key wording is “ongoing communities of professional peers organized around specific subjects.” That directly describes a Community of Practice: a peer-based network built around shared craft, experience, and learning. These groups support innovation indirectly because they improve knowledge flow, expose people to different practical experiences, and create occasional inputs into the Innovation Funnel. A Center of Excellence is usually more formalized and capability-governance oriented. “Villages of Experts” and “Kingdoms of Craft” are distractors and are not standard innovation-management terms. Therefore, the correct answer is Communities of Practice.
