Business communication involves the sharing of information within and outside an organization for commercial benefit. It can be defined as relaying information within a business by its people. Effective communication is vital for organizations as it allows for the exchange of information, opinions, plans and decisions between individuals. The basic process of communication involves a sender encoding a message and transmitting it through a channel to a receiver who decodes and provides feedback. Verbal communication can be oral, such as speeches and discussions, or written, like emails and letters. Non-verbal communication conveys messages through body language, eye contact, gestures and other unspoken means.
