Communication is the effective sharing of information between two or more people. It involves a sender, a message, and a receiver. There are various barriers that can interfere with effective communication, such as noise, lack of planning, assumptions, and cultural differences. Overcoming these barriers requires planning from the sender, active listening from the receiver, and choosing the right communication methods for the organization. Effective communication is important for businesses as it allows for coordination, leadership, productivity and job satisfaction. While it provides benefits like speed and flexibility, it also faces disadvantages like faulty messages if not planned properly.
