A center of excellence (CoE) is a corporate group or team that leads other employees and the organization as a whole in some particular area of focus such as a technology, skill or discipline. To that end, a business CoE may provide research, support, guidance, placement training and oversight for other employees and students. The area of focus can be anything that's important enough to the business to devote the necessary resources to. A CoE may be ongoing or temporary; group members may work in another capacity or be full-time in the CoE. A center of excellence is frequently used when an organization needs to take on a new technology or skill and manage its adoption. Major trends like BYOD (bring your own device) Cloud Computing and big data analytics often drive the adoption of CoEs as enterprises attempt to deal effectively with a rapidly evolving business environment.
