This document discusses the format of a presentation on communication. It begins by defining communication and listing its key characteristics such as being goal-oriented, two-way, perpetual, and human-focused. The importance of communication for smooth operations, productivity, job satisfaction and leadership is then covered. The main types of communication are formal/informal, verbal/written, and downward/upward/horizontal. Barriers to effective communication include poorly expressed messages, misunderstandings during transmission, lack of attention, unclear assumptions, insufficient adjustment to changes, and premature evaluation.
