A center of excellence (COE or CoE ), also called excellence center, is a team, a shared facility or an entity that provides leadership, best practices, research, support or training for a focus area. Due to its broad usage and vague legal precedent, a "center of excellence" in one context may have completely different characteristics from another. The focus area might be a technology (e.g. Java), a business concept (e.g. BPM), a skill (e.g. negotiation) or a broad area of study (e.g. women's health). A center of excellence may also be aimed at revitalizing stalled initiatives. The term may also refer to a network of institutions collaborating with each other to pursue excellence in a particular area. (e.g. the Rochester Area Colleges Center for Excellence in Math and Science). In contrast
