An '''Engineering Verification Test''' ('''EVT''') is performed on first [[engineering]] [[prototype]]s, to ensure that the basic unit performs to [[design]] goals and [[specifications]]. Verification ensures that designs meets requirements and specification while Validation ensures that created entity meets the user needs and objectives. Thus, verification means you are doing it right, while validation means you are doing the right things.

==Importance==

Identifying design problems, and solving them as early in the design cycle as possible, is the key to keeping projects on time and within budget. Too often, [[product design]] and performance problems are not detected until late in the [[product development]] cycle — when the product is ready to be shipped. The old adage holds true: It costs a [[penny (United States coin)|penny]] to make a change in engineering, a [[dime (United States coin)|dime]] in production and a [[United States dollar|dollar]] after a product is in the field.
