3. Why Create a Prototype? If a picture is worth a thousand words, how much is a prototype worth? Identify flaws, inefficiencies, and design alternatives Gauge reactions from potential customers, buyers, or investors

4. Form, Fit, and Function Physical, functional, and performance characteristics or specifications that uniquely identify a component or device and determine its interchangeability in a system Form: The shape, size, mass, weight, and other visual parameters which uniquely characterize an item. Fit: The ability of an item to physically interface or interconnect with or become an integral part of another system. Function: The action or actions that an item is designed to perform. What aspects of form, fit, and function are important to your design? Fertigator

5. Mock-Up/Presentation Prototype A three-dimensional representation of your invention that offers greater visual impact than a drawing would provide. Images courtesy of Dimension What form, fit, and function questions can be answered with a presentation prototype?

6. Functional Prototype A model intended to finalize the operational elements of your invention before it goes into production. What form, fit, and function questions can be answered with a functioning prototype? Types of Functioning Prototypes Full Scale Working Model Scaled Working Model Partial Model Virtual Model
