The document outlines the seven Cs of effective communication: completeness, conciseness, clarity, correctness, consideration, courtesy, and concreteness. These principles provide guidelines for choosing content and style of presentation adapted to the purpose and receiver of the message. Completeness means providing all required facts to avoid misunderstanding. Conciseness means being brief using the fewest words possible. Clarity involves using simple, familiar language and examples. Correctness refers to accurate language, facts, and information. Consideration means adapting the message to the receiver's perspective. Courtesy creates goodwill through sincerity and avoiding irritation. Concreteness makes the message specific and vivid rather than vague.
