How is a diary different from a policy statement in purpose and audience?

A diary primarily serves as a personal record for the writer, capturing thoughts, feelings, and daily experiences, making it introspective in nature. Its audience is typically the writer themselves, although it may be shared with close friends or family. In contrast, a policy statement is designed to communicate specific guidelines or principles to a broader audience, such as employees or stakeholders, with the intent to inform or direct behavior within an organization. The purpose of a policy statement is to establish clear expectations and standards, whereas a diary focuses on self-reflection and personal expression.
