It is at times of transition, however, that communication should be at its best. This definition comes from the Latin derivation, communis, meaning oneness or commonness of understanding. Based on this derivation communication takes on another dimension. As a process, communication is not simple. Complexities creep into the communication process from people through their attitudes, perceptions, orientations and ideas as well as the multitude of channels that can be used for transmitting information.
Every message has a sender and a receiver, both of whom are fully aware of the message.
Every message will be in one particular code or medium 3. Both sender and receiver who understands the code receive the message identically. Everyone understanding the code understands the message since its meaning is invariant, regardless of the circumstances or the identities of the sender and receiver. Therefore, in an organisational setting communication moves beyond encoding, transmitting and decoding. It can be likened to the social glue which holds the organisation together.
