Communication involves the sharing of ideas, information, or feelings between individuals or groups through various channels. There are formal and informal types of communication that can flow vertically, horizontally, or crosswise within an organization. Barriers to effective communication can occur at the semantic, emotional, organizational, or superior level and include issues like differing meanings, poorly expressed messages, assumptions, or organizational policies. Effective communication employs all three components of verbal messages, paraverbal cues like tone and pacing, and nonverbal body language. It is a two-way process that utilizes active listening, feedback, and clarity while being stress-free.
