The 5 C's of Business Writing
Coherent (orderly, logical, consistent relation of parts)
Make sure sentences are not too long or complicated.
Use appropriate language for the reader or audience.
Use technical terms if the reader is a specialist.
Use layperson's terms if the reader is not.
Use natural sounding words and phrases.
Say what needs to be said in the fewest possible words.
Get to the point.
The first draft is often too wordy. Edit, but include all relevant details.
Do not confuse concise with abrupt (see courteous).
Adopt a “you” attitude – one that sees the other person's point of view.
Treat the reader as you would like to be treated – with respect.
Do not accuse, threaten, scold, or belittle.
Remember that your business depends on good relations with customers and employees.
Check spelling, punctuation, and grammar (proofread).
Use correct format for letters or memos (do not forget to sign it).
