The word ‘Communication’ has been derived from the Latin word ‘Communis’ which means ‘Common’. Thus ‘Communication’, strictly, stands for sharing of ideas in common.
The term ‘Communication’ has many and varied meanings. Popularly speaking, it may refer to the various means or media of transmitting information from one individual to another from one place to another, e.g., telephone telegraph or television.
According to some, it primarily concerned with the transmission of information in a governmental organisation e.g., grapevine, the complaint box, the grievance procedure or the formal chain of command.
But the concept of communication with which we are primarily concerned is that it is the act of inducing others to interpret an idea in the manner intended by the speaker of writer. If one person speaks or writes something which is not understandable to others, it is no communication.
In short, the entire concept of ‘Communication’ in administration includes: 1. Transmission of information, order and instructions from the top administrator to the middle level administrator and down to the ordinary employees. 2. Transmission of reports, ideas, suggestions, complaints, grievances from the lower cadre employees to the top administration. 3. Cross communication between management groups and the worker groups. 4. Communication to the employees or the administration through extra-administration agencies such as union or other interest groups.
Herrbert A Simon observes, “Communication may formally be decisional premises are transmitted from one member of an organization to another.”
