This document discusses communication strategies and principles. It begins by defining communication as the transfer of meaning, not just the sending of messages. There are six principles of communication: it is dynamic, continuous, circular, unrepeatable, irreversible, and complex. Barriers to communication include physiological barriers like differences in senses, and psychological barriers where meaning is not understood. Developing a communication strategy requires considering the sender, receiver, message, media, code, feedback, noise, and effects. Strategic communication as a manager differs due to levels of responsibility, organizational culture and dynamics, and personality preferences.
