!!! Overview
A policy is simply, An official or prescribed plan or course of action.

A policy itself, provides no [compliance] and no enforcement.

Guidelines for making an effective [{$pagename}] are as follows:
* [{$pagename}] as far as possible should be in writing.
* They should be clearly understood by those who are supposed to implement them.
* They should reflect the objectives of the [Organizational Entity].
* To ensure successful [implementation] of a [{$pagename}], the top managers and the subordinates who are supposed to implement them must participate in their formulation.
* Conditions change and policies must also change accordingly. Hence, a [{$pagename}] must strike reasonable balance between stability and flexibility.
* Different policies in the [Organizational Entity] should not pull in different directions and should support one another.
* Policies should not be detrimental to the interests of society.
* Policies should be periodically reviewed in order to see whether they are to be modified, changed or completely abandoned.

!! [{$pagename}] Structure
A [provider|Provider of services] of the [{$pagename}] is a [Policy Information Point].

The digital representation of the [Policy] is provided by the [Policy Information Point] to the [policy Decision Point] which then passes the decision to the [Policy Enforcement Point] where the access is permitted or denied.

Obviously in some systems, all of the entities:
* [Policy Information Point]
* [Policy Decision Point]
* [Policy Enforcement Point]
* [Policy Administration Point]
May reside within the same [application] of the same host.

A [Policy Based Management System] is one where the system’s operation is determined by a set of [Policies|[Policy] evaluated when triggered by an [event].
