An engineering verification test (EVT) is performed on first engineering prototypes, to ensure that the basic unit performs to design goals and specifications.
[2] Tests may include: Identifying design problems and solving them as early in the design cycle as possible is a key to keeping projects on time and within budget.
[3] In the prototyping stage, engineers create actual working samples of the product they plan to produce.
This valuable information is used to validate the design as is, or identify areas that need to be modified.
Design Verification Test (DVT) is an intensive testing program which is performed to deliver objective, comprehensive testing verifying all product specifications, interface standards, Original Equipment Manufacturer (OEM) requirements, and diagnostic commands.
