This document discusses communication in organizations. It defines communication and explains its importance for planning, coordination, and performance. The communication process involves six elements: a sender encoding a message, channels to transmit the message, a receiver decoding the message, feedback, and potential noise. There are three main forms of communication: verbal, written, and nonverbal. Barriers to effective communication can be personal, organizational, or environmental. Overcoming barriers requires listening, feedback, cultural awareness, appropriate channels, and structured organization. Communication is important between organizations and the public to share information, gain support, and educate people.
