The sequence of concept development, styling development, engineering development and prototype development.
I can help you with any or all of these disciplines. The concept and styling stages are often executed on a computer in the form of 3D computer models that enable my clients to evaluate, with great accuracy, how a product will look, how much a product will cost to tool and produce and estimate how a product will function. The prototype stage can accurately demonstrate how a product will perform.
The prototype stage is always the most important stage as it is the first physical demonstration of the design and can reveal its strengths and weaknesses. Sometimes, one or more of the previous stages must be revisited to improve the design. This is always much less costly than having to make design changes at later stages of development.
