Good communications are the life blood of any enterprise large or small. Organizations have established communication systems that managers can use to communicate back and fourth effectively and efficiently. There are five basic forms of organizational communication. These five channels can also be divided into formal and informal communication. Formal communication channels are planned and established by the organization.
Informal channels allow information to be carried outside formal channels.
Downward communication is the most common communication system used in an organization. This is the communication style that deals with the flow from a manager to a subordinate. Upward communication is the communication method used by subordinates to their supervisors. Communication between manager to manager, or coworker to coworker is known as horizontal communication. This communication method involves work flow between peers with little or no control by managers.
