1、EVT (Engineering Verification test phase) Engineering verification test stage , Design verification at the initial stage of product development .---- The feasibility of

The product has just been designed for engineering samples , There will be many problems , The focus of this stage is to verify the main functions of the product , Take mobile phone products as an example , for example ： speaker test 、 receiver 、 Whether the main functions such as Bluetooth are enabled , So that the R & D personnel can modify the product design 、 debugging .

2、DVT (Design Verification test Phase) Design verification test phase ----- Reliability + Operability

All designs of the product at this stage have been completed , The key point is to test the whole performance of the product , Ensure that all designs meet specifications . In general EVT The structure of the stage product has not been finalized , The product cannot be tested for reliability , therefore DVT In addition to the software and hardware tests, the tests at this stage , Need to add reliability test （ Sexuality ： reliability 、 Security 、 Maintainability 、 Supportability 、 Testability 、 Environmental adaptability ）,DVT The process of stage test and review is the same as EVT Stage .

3、PVT (Production Verification test Phase ) Production validation test stage ---- Security + stability

PVT At this stage, some products need to be trial produced in small batches , The main functions of the product design are fully realized and meet the standard requirements , Ensure that the factory can comply with SOP（ Standard operating instructions ） Produce products that fully meet the design requirements .

4、MP (Mass production Phase) Mass production stage ----- comfort + Repeatability

After the above stages of design 、 test 、 review 、 debugging / modify , The product design fully meets the design and customer needs , The factory can mass produce market-oriented products .
