        1.  An organised, documented set of procedures
        and guidelines for one or more phases of the {software life

        the procedure; a step-by-step "cookbook" approach for carrying
        out the procedure; and an objective (ideally quantified) set
        of criteria for determining whether the results of the
        procedure are of acceptable quality.
