Distinguish between policy, procedeure, method and rules?

Answer 1

policy is "a definite course or method of action selected from among alternatives and in light of given conditions to guide and determine present and future decisions"
"Procedures" describe the act or series of steps that are used to carry out a policy. While a policy simply states what happens under an individual circumstance, the procedure more clearly defines 1) who will carry out the process, 2) the time frame over which the action is implemented, and 3) the actual process of how the policy will be carried out.

Method is a means or manner of procedure, especially a regular and systematic way of accomplishing something: a simple method for making a pie crust; mediation as a method of solving disputes.

Rule is an authoritative, prescribed direction for conduct, especially one of the regulations governing procedure in a legislative body or a regulation observed by the players in a game, sport, or contest.
