INTRODUCTION : Communication is essentially to-and-fro transfer of information between individuals, departments as well as between organisations. Therefore, it is an important aspect of the functions of any organisation. At the heart of any well-run department will be a good system of communication. In order to be effective, communication must take place at the proper time, must be accurate and must occur speedily.
