Policies are:

Policies serve as established frameworks that guide decision-making and define the boundaries within which actions and decisions can occur. They set the standards for behavior within an organization and outline the acceptable practices that align with the organization's goals and values. By delineating what is permissible, policies create a consistent environment for operations and establish a basis for accountability.

In contrast, predetermined goals focus more on desired outcomes rather than acting as the guiding framework for actions. Statements that provide direction and motivation can be part of policy creation but do not encapsulate the broader function of policies as guiding principles. Specific tasks to be performed are typically addressed through procedures or protocols rather than policy, which is more about guiding decisions than detailing actions. Therefore, the function of policies as guidelines that define the scope of permissible activity is the most accurate description.
