==Tests==

Line 8 ⟶ 11:

* [[Conformance test]]

* [[Electromagnetic interference]] (EMI) pre-scan

* Thermal and 4 four-corner test

* Basic parametric measurements, specification verification

==Importance==

Identifying design problems, and solving them as early in the design cycle as possible, is thea 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.<ref>{{Cite book |last1=Dong |first1=Jin Song |url=https://books.google.com/books?id=9_VqCQAAQBAJ&dq=Engineering+validation+design+flaws&pg=PA207 |title=Formal Methods and Software Engineering: 5th International Conference on Formal Engineering Methods, ICFEM 2003, Singapore, November 5-7, 2003, Proceedings |last2=Woodcock |first2=Jim |date=2003-11-06 |publisher=Springer |isbn=978-3-540-39893-6 |language=en}}</ref>

==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]]

* Electromagnetic compatibility ([[electromagnetic compatibility|Electromagnetic Compatibility (EMC)]]) testing and certification
