Communication is the exchange of thoughts, opinions, or information through speech, writing, or signs. Organizational communication differs from usual communication in that it is the structured and directed flow of information within an organization to coordinate activities and reach individual and organizational goals. The key elements of the communication process are the sender, encoding, message, channel, decoding, receiver, and feedback. Communication can be verbal through oral/spoken communication or written communication, or non-verbal through body language and other means. Organizations utilize upward, downward, and lateral/horizontal communication.
