 Self-governing organizations follow parliamentary procedure to debate and reach group decisions—usually by vote—with the least possible friction.Rules of order consist of rules written by the body itself (often referred to as bylaws), but also usually supplemented by a published parliamentary authority adopted by the body.Typically, national, state/provincial and other full-scale legislative assemblies have extensive internally written rules of order, whereas non-legislative bodies write and adopt a limited set of specific rules as the need arises.
