Memorandums are used for ________________________ communication.

Memorandums are commonly utilized as a form of communication within the confines of an organization. They serve as an effective means for sharing information, updates, or directives among different teams, units, or personnel within the same department or organization. This makes them particularly valuable for internal communication, where clarity and formality are often required.

When focusing on infra-departmental communication, memorandums allow for the distribution of key information or policy changes in a clear and concise format. This can help ensure that all members are on the same page and understand the directives being conveyed. The ability to document communication in this format also serves to create a record which can be important for accountability and future reference.

In contrast, external communication typically involves correspondence with parties outside the organization, which would not utilize memorandums in the same way. Similarly, inter-departmental communications usually involve more comprehensive reports or emails, rather than the straightforward and formal memo format. Public communication, on the other hand, is generally directed at outside audiences and would require different formats or channels entirely, such as press releases or public notices. Thus, memorandums are specifically tailored for infra-departmental use, making them an essential tool for efficient internal communication within an organization.
