all involved in the life cycle of a product, from the design stage until its withdrawal from service. The purpose of this guide is to:  encourage specification writers and designers to make greater use of existing recognised standards and at the same time to reduce the use of company standards;  increase the awareness among specification writers, designers, manufacturers and users of company standards of the value and importance of being part of a joint multilateral approach to formalising, through standards, requirements for which the audience is generally known;  provide methodological support for the users of company standards when undertaking the rationalisation of various requirements. The achievement of this objective will be measured by:  the reduction in the total volume of standards documentation, with an increase in the use of public standards as opposed to company standards,  lower production costs arising from a reduction in product diversity.
