A memorandum (memo for short) is a form of communication used within a company to request or exchange information, make announcements, and confirm conversations. Memos frequently convey information to large groups — an entire team, department, or organization. Generally, the topic is quite narrow and apparent at a glance. Memos tend to be written in the first person (I or we) and can range from very informal (if written to a peer) to extremely formal (if written to a high-ranking superior on an important matter). Most are short, but the format can be used to convey proposals and reports; long memos freely use headings, subheadings, lists, and other features that are easy to skim. (See Figure 17.6.)
