What is a memo primarily used for?

A memo is primarily used for internal communication within an organization or team. Its concise format allows for quick dissemination of information, updates, or reminders among employees. Memos are typically less formal than reports or official documents and are designed to convey specific messages efficiently.

In the context of organizational communication, a memo serves as a practical tool for sharing important announcements, changes in policies, or team directives. This informal nature fosters quicker responses and keeps all team members informed while encouraging open lines of communication.

Other options, such as a detailed report of an investigation, a formal invitation to meetings, or a summary of regulations, represent different forms of communication that have distinct purposes and levels of formality. Thus, they do not align with the primary function of a memo as a brief note intended for internal dialogue.
