As written in this article by Nick Sanchez, http://www.stfrancis.edu/content/ba/ghkickul/stuwebs/btopics/works/comproc.htm,
there is a process to communication that he states “can best be summarized as the transmission of a message from a sender to a receiver in an understandable manner. ”
Sanchez goes on to identify the steps in the process of sending/receiving messages, from the sender encoding the message, transmitting the message (via a medium,) and decoding the message at the receiver which orders some type of meaning to the brain to interpret the message. Finally, feedback is brings the process to a complete circle so that the receiver can respond to the sender in some type of way, evaluating the effectiveness of the message.
I think it is important to understand this process so that when in business, or organizing a plan for communication, one can understand how to target their audience (or receiver) and better pass on the information effectively.
