To ensure clear communication in memo form, one should:

Using the 5 Ws and H—who, what, when, where, why, and how—provides a structured approach to conveying information clearly and comprehensively in a memo. This framework ensures that all essential details are included, making it easier for the reader to understand the message without needing additional context. By asking these questions, writers can cover various aspects of a situation or message, leading to well-rounded communication.

Practicing writing or choosing words carefully are both beneficial strategies for effective writing in general. However, they do not specifically address the comprehensive inclusion of information in a memo as effectively as applying the 5 Ws and H. This method directly supports clarity and thoroughness in communication, which is essential for memos that often require precise and actionable information.
