Except for luxury goods or brands (e.g., Swarovski crystals, Haute couture fashion, etc.), most goods, even exclusive products, rely on cost reduction, if these are mass produced. The same is valid for the functional production strategy of mass customization. Through engineering design physical interfaces between a) parts or components or assemblies of the product and b) the manufacturing equipment and the logistical material flow systems can be changed, and thus cost reducing effects in operating the latter may be achieved.
