This chapter outlines and explains the key stages of the design process from detail design to manufacture, and addresses marketing, branding, and sales. The way in which a product is made has a big effect on decisions taken by the designer during the detail design phase—after all, it is important that the product can be made. It is vital, therefore, that the correct manufacturing processes are chosen at the detail design stage so that a design does not have to be changed later, which may be detrimental to the budget, schedule, and the integrity of the original design.
