Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea. A User Experience Prototype captures enough aspects of the intended design that it can support user research. 2  A Visual Prototype captures the size and appearance, but not the functionality, of the intended design.
