Corporate communication involves managing a company's external image and internal identity. The external image is the mental picture that springs to mind when a company's name is mentioned, while internal identity encompasses the visual elements a company uses to communicate its business philosophy. It is important for a company's external image and internal identity to be consistent in order to be successful. Corporate communication also involves four key functions: marketing communication, management communication, organizational communication, and financial communication. These functions help a company understand how it affects both internal and external stakeholders.
