Your Communication should follow the three Cs, if they have to impact your audience. The three Cs are Correct, Clear and Concise. 

No Scope for Error

Did poor Communication lead to Asiana Crash in July 2013?

Communication is the base of our existence today. When we get a bottle of liquor, while asking for a glass of water, we realize the importance of good communication. In a shop at the Frankfurt Airport it was shocking for me to see that decimal points were not being used in the rate list. Something which was worth one Euro was written as 100, while something worth 25.45 Euros was written as 2545. It became worse when the sales person did not understand English. One can always find grave examples of what happens when Communication fails… but here the emphasis is on improving Communication. 

The First C – Correct

Though there is not much explanation needed to say why, what you say should be correct, let me highlight a few thoughts. Many times, we believe we have said or written everything correctly. Communicators read again and again to check whether the words are able to convey what they intended to. Sometimes an inadvertent mistake of leaving out a ‘not’, can altogether change the meaning. 
Eg: 1) The Prime Minister did not see the warning. 
2) The Prime Minister did see the warning. 

The Second C – Clear

I interpret this clear as clarity in what you say or write. When someone mumbles or gives only half the instruction, the chances are that you may miss out on what the person really wanted to say. Worse you may misinterpret the person to be rude. The same holds true to the way you write. In the era of SMSs, sometimes, the really short message can be misread. Eg: Sry Cud not B wid U ! Can be very meaningful to your friend but may not mean anything to someone who doesn’t understand this lingo. 

The Third C – Concise

‘Count your words’ is a general rule taught in Journalism schools. One apt word will substitute many. Short sentences will ensure that it conveys the exact meaning. A longish sentence, meandering about the subject can confuse the reader. It’s thus not surprising that scripts written for Television and Radio, generally use short sentences.
