This definite purpose is, in fact, one of the principal differences between casual conversation and managerial communication. Effective communication in the organization centers on well-defined objectives that support the organization's goals and mission . Supervisors strive to achieve understanding among parties to their communications. Organizational communication establishes a pattern of formal communication channels to carry information vertically and horizontally. To ensure efficient and effective accomplishment of objectives, information is exchanged.
Information is passed upward from employees to supervisors and laterally to adjacent departments.
Instructions relating to the performance of the department and policies for conducting business are conveyed downward from supervisors to employees. The organization carries information from within the department back up to top management. Management furnishes information about how things are going, notifies the supervisor of what the problems are, and provides requests for clarification and help. Supervisors, in turn, keep their employees informed and render assistance. Also, supervisors communicate with sources outside the organization, such as vendors and customers.
