Which of the following is primarily used for announcing policies, instructing employees, and requesting information?

Memos are designed specifically for internal communication within an organization, making them ideal for announcing policies, instructing employees, and requesting information. They are typically concise and focus on conveying important information quickly to a specific group or department, ensuring that employees are well-informed and directives are clear. Memos often have a standardized format that includes a heading, a brief introduction, and clear, actionable items, which aids in ensuring that the message is understood without unnecessary complexity.

In contrast, letters are generally used for more formal communication, often intended for external stakeholders or for situations where a personal touch is required. Feasibility reports are comprehensive documents that analyze the viability of a project or proposal, serving a very different purpose than the straightforward communication provided by memos. Inquiry letters are specifically crafted to solicit information from external sources rather than communicate policies or instructions within an organization.
