Excellence theory
The Excellence theory is a general theory of public relations that “specifies how public relations makes organizations more effective, how it is organized and managed when it contributes most to organizational effectiveness, the conditions in organizations and their environments that make organizations more effective, and how the monetary value of public relations can be determined”. The excellence theory resulted from a study about the best practice in public relations, which was headed by James E. Grunig and funded by the Foundation of the International Association of Business Communicators (IABC) in 1985.
