The Industrial Designers Society of America (IDSA) defines industrial design as "the professional service of creating and developing concepts and specifications that optimize the function, value and appearance of products and systems for the mutual benefit of both user and manufacturer."
In other words, industrial design helps to bridge the gap between the needs of product users and the needs of product makers. It is the job of the industrial designer to interpret the consumers' wants into a product design that can be engineered and produced.
Industrial designers must be able to innovate solutions to problems, and communicate those solutions through effective presentation. Typical communication techniques that the industrial designer uses to communicate concepts include sketching, illustrating, rendering, computer models, and physical prototypes.
