The Online Business Dictionary defines communication as a two-way process of reaching mutual understanding, in which participants not only exchange (encode-decode) information, news, ideas and feelings but also create and share meaning. In general, communication is a means of connecting people or places. In business, it is a key function of management. An organization cannot operate without communication between levels, departments and employees.
Gilbert Amelio, a former President and CEO of National Semiconductor Corporation said that “Developing excellent communication skills is absolutely essential to effective leadership. The leader must be able to share knowledge and ideas to transmit a sense of urgency and enthusiasm to others. If a leader can’t get a message across clearly and motivate others to act on it, then having a message doesn’t even matter.” It is simply impossible to become a great leader without being a great communicator.
