A functional appearance model is a prototype that 'looks like' and 'works like' a production product. Though made from prototype materials, these models simulate actual finishes and colors as well as mechanisms. There are, however, occasional limitations to what can be achieved with prototypes so it is important to understand the potential differences between a functional appearance prototype and an actual manufactured product.
Functional appearance models are often used for trade shows and focus groups. Product QuickStart creates functional appearance models for products in a number of industries.
