List the three components of effective communication and give an example of each
Marrrta [24]

Answer:

The three components of effective communication are:

  1. Sending Communication
  2. Receiving Communication
  3. Feedback

Explanation:

<h3>1) Sending Communication</h3>

One should think about what he is going to say, structure his message and focus clearly on a the purpose of sending a message. For example if an employer wants to communicate an employee to improve his performance, he should focus hid communication on the results rather than on his failures.

<h3 /><h3>2) Receiving Communication</h3>

The person on the other end of the communication should be a good listener. For example in the example given, even if the employer effectively communicates his side of the communication, but the employee is not paying his full attention to what his boss is saying, he wouldn't be able to make much of a difference.

<h3>3) Feedback</h3>

After sending and receiving communication, feedback should be given to complete the communication effectively. For example the employer may tell his boss about what he understood from his boss's speech, or what will he do to improve his performance.
