"Design is the cornerstone of creating and producing any structure, product or item either for bespoke use or mass reproduction. Anything that is created, constructed or manufactured relies on design whether for aesthetic, functional or critical purposes. Of paramount importance is the designer's understanding of the intended use and the application of the product and their subsequent ability to translate this into a finished design. Of equal importance to the designer is an understanding of the operating environment in which the product is to be used and how this environment is controlled by such considerations as regulations, standards or social norms. These considerations may have a direct influence (such as the regulations surrounding health and safety) or indirect influence (such as ethical or moral concerns) on the design process. Additionally, the actual individuals who will use the product should be considered, as well as any others who may come into contact with it. What is important in any design process is that the criteria of the design requirement are developed within this sphere of considerations and; that it is capable of being subsequently produced accurately to that requirement. This is known as the input-process-output cycle"--
