Try to recall a major miscommunication or misunderstanding that you were involved in and its consequences. Describe such situation. In what component/s of the communication process do you think did the problem originate? Explain what you did about it and give suggestions on how problems as such can be avoided in the future.

Answers

Answer:

This had to do with money.

My brother had called me over the phone to request for $20 dollars. He needed it urgently for a payment deadline that was closing in 3 minutes.

It took about 2 minutes to send the loan to him. He called back upon receiving the bank alert screaming that what he asked for $30 and not $20.

Unfortunately, he missed the payment deadline.

Explanation:

Depending on the model you are looking at, there are between 5 to 7 components of the communication process. They are, encoding, medium of transmission, decoding, and feedback.

The component where the distortion arose was from the encoding and the channel or medium of transmission. 20 does sound like 30 when pronounced over a muffled channel.

Given that it was a phone call against a noisy background, errors in decoding the message was bound to occur.

What my brother could have done was to encode in such a manner that it would be impossible to miss. Whilst I confirm or decode the message in such a way that both parties are on the same page.

For example, the call could have gone like this:

Brother: Hello, do me a quick one. I need $20. That is Two-Zero

Me: Do you mean two as in T for time, W for wallet and O for Orange?

Brother: Yes. I have less than 3 minutes to sort this.

Me: You'll get it within the minute.

Brother: Thanks a lot

Me: Its a pleasure

Cheers
