A center of excellence (COE) is a team, a shared facility or an entity that provides leadership, best practices, research, support and/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.
