《Beginner’s Guide for Hardware Startup (1) - What is EVT? 》
Speaking of the hardware manufacturing, the EVT/DVT/PVT phases are “must have” knowledge if you want to prevent early stage fail of the average failure rate 32% and 81% delivery delay rate in all hardware startups (according to the statistics of Kickstarter.)
The EVT/DVT/PVT phases start after the design and development process. EVT performed on prototypes to verify if the design meets the specification. During this phase engineer will put their idea and design on the “Big board” – which is a big circuit board contains the design they need to verify and test. The best situation is only do the EVT phase once to save the cost of production. Generally speaking, EVT stage consists of basic functional tests, parametric measurements, and specification verification.
