design

the process of translating a product idea into a product which can be produced and marketed on a commercial basis. Though design is a creative process it has economic consequences insofar as a product's shape, configuration and performance affect its marketability and its cost of production. In order to achieve high product variety without involving an excessive variety of components, designers often use common, interchangeable parts and design products on a modular basis.

In order to remain competitive, firms need continuously to review the design of their products in the light of new developments in materials and processes. The technique of VALUE ANALYSIS is used to identify possible sources of cost savings without impairing a product's performance. See COMPUTER-AIDED DESIGN, NEW PRODUCT DEVELOPMENT.
