ABSTRACT
As was explained in chapter 4, the development stage of a product may include making a prototype. This is usually a “one of a kind” product to show that the product actually exists. The prototype is most often very expensive and will normally only partially resemble the eventual product that will be produced in volume. Once it appears that the prototype has commercialization potential, the product moves to the demonstration stage. This stage is a life-sized, real-world example of the product that is put into actual practice or use. It is during this stage that user feedback starts to change the product to make it better able to meet the user’s purpose. Changes in design, fabrication, and components can alter the product substantially from the image of the prototype, and the end result will be a more functional product. Once a dominant design and form have been demonstrated, the product is ready for commercialization.
