Policy is a deliberate system of guidelines to guide decisions and achieve rational outcomes. A policy is a statement of intent and is implemented as a procedure or protocol. Policies are generally adopted by a governance body within an organization. Policies can assist in both subjective and objective decision making. Policies used in subjective decision-making usually assist senior management with decisions that must be based on the relative merits of a number of factors, and as a result, are often hard to test objectively, e.g. work–life balance policy. Moreover, Governments and other institutions have policies in the form of laws, regulations, procedures, administrative actions, incentives and voluntary practices. Frequently, resource allocations mirror policy decisions.

The rule of law is a political ideal that all citizens and institutions within a country, state, or community are accountable to the same laws, including lawmakers and leaders. It is sometimes stated simply as "no one is above the law". The term rule of law is closely related to constitutionalism as well as Rechtsstaat. It refers to a political situation, not to any specific legal rule. The rule of law is defined in the Encyclopædia Britannica as "the mechanism, process, institution, practice, or norm that supports the equality of all citizens before the law, secures a nonarbitrary form of government, and more generally prevents the arbitrary use of power."
