When you respond to the source, intentionally or unintentionally, you are giving feedback. Feedback is composed of messages the receiver sends back to the source. Verbal or nonverbal, all these feedback signals allow the source to see how well, how accurately (or how poorly and inaccurately) the message was received. Feedback also provides an opportunity for the receiver or audience to ask for clarification, to agree or disagree, or to indicate that the source could make the message more interesting. As the amount of feedback increases, the accuracy of communication also increases. [8]
For example, suppose you are a sales manager participating in a conference call with four sales reps. As the source, you want to tell the reps to take advantage of the fact that it is World Series season to close sales on baseball-related sports gear. You state your message, but you hear no replies from your listeners. You might assume that this means they understood and agreed with you, but later in the month you might be disappointed to find that very few sales were made. If you followed up your message with a request for feedback (“Does this make sense? Do any of you have any questions?”) you might have an opportunity to clarify your message, and to find out whether any of the sales reps believed your suggestion would not work with their customers.
