Policy:
a course or principle of action adopted or proposed by an organisation or individual.
Synonyms:
plans, strategy, blueprint, approach, scheme, programme, schedule, code, system, guidelines, intentions, theory, line, position, stance, attitude, practice, custom, procedure, wont, way, routine, style, convention, mode, rule . . . the list goes on.
Personally I only hang the term 'policy' onto something which the organisation executive (not me) has actively decided / agreed upon. If it's just my own good idea, then I may call it a strategy, plan, guidance, rules, procedure, depending on intended audience.
