Product development Phase EVT DVT PVT MP

PLM (Product Lifecycle Management) SYSTEM:PLM is to assist the product in the successful completion of the new product development (Npi:new product Introduction), as well as the amount of post-natal related engineering technology execution work, Large to five stages planning (product conception phase), EVT (engineering validation and testing phase), DVT (design verification and testing phase), PVT (production validation and testing phase), MP (mass production phase).

EVT (Engineering Verification test) Engineering validation test phase

Design validation at the initial stage of product development. Many products have just been designed for engineering samples, a lot of problems need to be the possible design problems are revised, focusing on the design integrity, whether there are missing any specifications. Including functional and safety test, generally by Rd on the sample to fully verify, because it is a sample, the problem may be more, the test may be done n times.

DVT (Design verification test) Validation test phase

This is the 2nd phase of research and development, all of which have been completed with a focus on identifying design issues and ensuring that all designs conform to specifications. Validated by Rd and DQA (Design quality assurance). At this point the product is basically stereotyped.

DMT (Design maturity Test) Maturity verification

Can be performed at the same time as DVT, the MTBF of the test product under the main limit conditions (Mean between Failure), HALT (High Accelerated Life Test) & HASS (High accelerated Stress screen) is an effective method to test the potential defects of a product.

MVT (mass-production Verification test) Production verification test

Verify the high-volume consistency of the product at mass production, verified by DQA.

PVT (production/process verification test) production/process validation testing phase

This phase of the product design to complete, all design verification also to end, and finally only to do the amount of prenatal verification, to determine the factory has a way to follow the standard operating procedures to make the original design of the product.

MP (Mass Production) mass production

After all of the above testing stage, the factory can be a large number of production of the design, in theory to enter the production stage, all the design and production should be without any omissions and errors, to become the official market products.

Evt:engineering Verification Test (Engineering verification test phase) Generally, the sample produced at this stage is only the circuit board, and is the kind of a large board, which we often call "big Board", the research engineer will usually first put the idea that he wants to verify Or a design that can't be decided on the board.      So this design is usually a hardware circuit for engineering verification (verification), debugging (Debug), you may be hard to imagine that the board will become a future light mobile phone or product. In general, if the development of new things, the first time just design, the problem must be many, some even just experimental nature, research and development engineers may not have a bottom, in the end, what kind of feasible design plan to take?     So there may be several times of the EVT production, depending on the status of Research and development, the focus is to have enough time and samples so that the development engineer can verify his ideas, to pay attention to the production of every sample is a large fee, can be used once the evt to solve the words do not do the second evt.     If the design is to modify the existing product design, it will be relatively simple, because there will not be too many new technologies, also do not need too much evt sometimes even skip the evt directly. EVT Focus: All possible design issues must be proposed for one by one correction, so focus on considering the feasibility of the design and check if any specifications have been omitted.

Dvt:design Verification Test (Design Verification test phase) This is the second phase of research and development, and all the design's thinking should have been completed.      This time will add the shell of the body, in addition to the circuit board to achieve the actual size, so that the circuit board can be put into the body shell. This stage of the body shell is likely to start with a large resin with a laser engraving produced by the sample (mockup), or with a soft mold produced only, in order to verify the actual mold before the production, to validate the design of the body shell is in line with the requirements, because the real cost of the mold is very expensive,      So you have to verify before you can open the mold. This stage to verify the function of the machine, the focus is the design and manufacturing problems to find out to ensure that all the design is in line with the specifications, but also production.

Pvt:production Verification Test (production verification test phase) This phase of the product design should be changed to complete, all the design verification is over.      This stage of the trial production is to do a lot of prenatal manufacturing process testing, so it is necessary to produce a certain amount of products, and all production procedures to meet the manufacturer's standard procedures. Also calculate whether all the tools, test fixture and production equipment quantity can meet a large number of production capacity (capacity).
