==Design Verification Test==
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|Original Equipment Manufacturer (OEM)]] requirements, and diagnostic commands. It consists of the following areas of testing:
* Functional testing (including [[Usability testing|usability]])
* Performance testing
* Climatic testing
* Reliability testing
* Environmental testing
* [[Mechanical testing]]
* [[Mean time between failures|Mean Time Between Failure (MTBF)]] prediction
* [[Conformance testing]]
