Conciseness is writing means expressing the necessary information in as few words as possible.  Say what you need to say without cluttering your communication with irrelevant information or needless words.

Checklist for conciseness:

• Are my sentences short?
• Are my paragraphs short?
• Have I used simple, easy to understand words?
• Have I used bullets or numbered lists whenever possible?
• Have I avoided unnecessary repetition?
• Have I eliminated excessive information?
• Have I avoided clichés? (Phrases that have become overused e.g. what goes around comes around)
