The document provides guidance on writing effective memos within an organization. It defines memos as informal written communications between colleagues used to share information. The key parts of a memo are identified as the heading with to, from, date and subject lines, an opening paragraph stating the purpose, a summary or body, and a closing statement. Guidelines are presented for successful memos, including introducing the topic clearly, using highlighting techniques, and providing a directive or complimentary close. An effective memo checklist is also included to ensure the correct format is followed and the writing is clear, precise and free of errors.
