Feedback is the receiver's response to the attempt by the sender to send the message. Feedback is the key to determination by the sender of whether or not the message has been received in the intended form. Feedback involves choice of channel by the receiver of the original message. The channel for feedback may be quite different from the original channel chosen by the sender. Effect on the receiver completes the communication process.
Effective communication is the original sender having the desired effect on the receiver.
Communication at its best minimizes misunderstanding between sender and receiver. The sender can not transplant a message or idea. This simplified version of a complex process can be a powerful tool for thinking about one's communication skills, diagnosing communication problems and developing plans for improvement of communication. The good news about communication is that improvement is almost always possible. The bad news is that perfection in communication escapes everyone.
