A memo, short for memorandum, is a written message that is typically used in a professional setting. It is a brief internal communication that informs a group of people about a specific problem, solution, or event. Memos are designed for official internal communications of a business or organization and are often sent to an entire organization but are also useful for informing a single department, team, or smaller group of people. They are typically more formal in tone and language than emails, which are most effective when they’re short and to the point. A memos concise format is relatively standardized in order to create accessibility to any reader. They open with a heading including a "to," from," "date," and "subject". A break in the text would then be followed by an opening paragraph, which would more than likely describe the purpose of the memo. Context is then added to the document, followed by a section of specific actions. The purpose of a memo is to bring immediate attention to information in a quick and brief manner. Memos can communicate important information efficiently in order to make dynamic and effective changes.
