Communication is the effective sharing of information between two or more people through messages. The basic elements of communication are the sender, the message, and the receiver. Communication allows organizations to inform, instruct, share information, motivate workers, lead the organization, and control and manage. However, there are also barriers to effective communication like noise, lack of planning, incorrect assumptions, cultural differences, and emotions. Overcoming these barriers requires planning from the sender, active listening and open-mindedness from the receiver, and choosing the right communication channels within the organization. Effective communication provides advantages like speedy information flow, coordination, and leadership while lack of planning, faulty messages, and poor listening can create disadvantages.
