Oral communication is the transmission of messages in face-to-face conversation. For example a meeting of inventory management department at Tesco has been called in which all the different managers of inventory management department took part. At times oral communication lead to clear communication results as the respondents can ask question and the other party can provide immediate feedback. On the other hand oral communication may lead to some miscommunication as no written records are kept for the communication. For example the Shift Manager writes memos to all the functional heads regarding the new office timing. In written communication the sender and receiver exchange messages in written form, but this method served from the fact that the parties in the communication process may not be able to provide immediate feedback. According to Leavitt written communication need careful preparation of messages because anything put in writing become a public record (Leavitt, 1991). On the basis of style communication can formal and informal. Formal communication use organization channels to transmit or received messages. For example the communication between Vice President Marketing and Marketing Manager of Tesco regarding the new promotion budged can be called formal communication. Formal communication can be upward, downward, or horizontal. In upward communication (when Marketing Manager writes to Vice President Marketing)—a subordinate transmit a message to a superior using the organizational structure of the firm. On the other hand in downward communication (from Vice President Marketing to Marketing Manager) a superior (Vice President Marketing) transmits a message to subordinate (Marketing Manager), while the horizontal communication is between two peers working at the same level of organizational structure (For example the communication that took place between Brand Manager Group A and Brand Manager Group B).
