What are the parts of a memo?

A memo consists of two parts: the identifying information at the top, and the message itself. At the top, identify for whom the memo has been written, who is sending it, the subject, and the date. The subject line serves as the memo's title.

The style and tone you use in a memo will be determined by your audience: You can use a casual tone in a memo to a coworker you know well, but you should use a more formal tone in a memo to your boss. It's important to organize your memos well. Most longer memos consist of an introduction, a discussion, and a conclusion. In the introduction, tell readers what prompted you to write (such as a problem or question about a specific procedure or policy), and provide any necessary background information. In the discussion section, or body, indicate what changes are necessary to address that problem or question. In the conclusion, state specifically how you want the reader to respond.
