Communication is an ongoing, dynamic process involving both transmitting and receiving verbal and nonverbal messages. To be fully functional, communication must include a feedback component that allows assessment of the effectiveness of the communication. Models of communication stress various relationships between senders and receivers, focusing on their attitudes, perceptions, and objectives. Other models address the factors affecting the ability of communicators to transmit meaning directly. The communication of a variety of information is vital to organizational success. Organizational communication systems have three components: the design of the formal communication subsystem, the organizational climate, and the interpersonal skills of those communicating. To understand an organization's communication fully, administrators must be aware of the needs, desires, and skills of the individuals making up the organization. Among the communciation skills individuals can develop are listening skills, listening behaviors, recognition of a listener's inability to assimilate additional information, skills in both small-group interaction management and public presentation, writing skills, and the ability to recognize indications that those receiving messages are not perceiving the intended meanings.
