Identifying design problems, and solving them as early in the design cycle as possible, is the key to keeping your projectprojects on time and within budget. Too often, [[product design]] and performance problems are not detected until late in the [[product development]] cycle — when you'rethe gettingproduct is ready to shipbe your productshipped. The old adage holds true: ItsIt costs a penny to make a change in engineering, a dime in production and a dollar after a product is in the field.

In the [[Prototyping]] stage, engineers create actual working samples of the product they plan to produce. Engineering Verification Testing (EVT) is used on prototypes to verify that the design meets pre-determined specifications and design goals. This valuable information is used to validate the design as is, or identify areas that need to be modified.
