ATTACHED MEMORANDUM
1-1. COMMUNICATION ACCURACY
One of man's characteristics is his ability to communicate ideas. Man has developed highly sophisticated
methods to transfer ideas visually, orally, mechanically, and electrically. Whatever the method, the primary
function of any communication system is to accurately transfer information. Distortion in the received sound or
variation from the original printed word may affect the mental image formed by the listener or reader. It follows,
therefore, that if communication between two people is to be successful, the precise order and form of the original
sounds or words must be maintained during the information transfer process. All other system characteristics are
secondary in importance to this function.
