Chapter 6 Rapid Prototyping

What is Rapid Prototyping?

• The process by which a model of the final product can quickly be made

• Changing the design of something after production has already begun

• When companies or teams are working on multiple aspects of the same design at one time

• Designing something while competing against other departments

What is the major importance of a prototype?

• to impress investors

• to show how the item works

• to get a patent

• to place as a decoration
