The document discusses the seven C's of effective communication: completeness, conciseness, consideration, concreteness, clarity, courtesy, and correctness. It defines each C and provides examples of how to apply it to ensure messages are fully understood. Completeness means providing all necessary information. Conciseness means delivering the message in the fewest words. Consideration means focusing on the receiver's perspective. Concreteness means using specific rather than general words. Clarity means choosing precise language all parties will understand. Courtesy means being tactful and respectful. Correctness means proper grammar, punctuation and spelling. All seven C's can improve both oral and written exchanges.
