How to Conduct a Design Verification Test
A Design Verification Test (DVT) proves that the drawings, if followed correctly, will produce a product that meets the requirements. In order to avoid a myriad of issues, a DVT should be conducted before the product is released to manufacturing.
How do you conduct a DVT? Here is an outline to get you started:
- Start with the Requirements Document (RD). After all, the RD defines “it works.”
- If there is no RD, develop one. You can download our RD tool here.
- Hopefully, the requirements are enumerated and objective. If not, now is the time for some editing.
- Write a formal DVT test procedure. You will likely go through DVT several times during the product’s lifetime. Formal means it is a controlled drawing that complies with the drawing control procedures.
- This DVT test procedure should include a test procedure document and a test record document with acceptance criteria. You can download our Test Record Drawing here.
- For each enumerated requirement, there should be a corresponding test procedure and test record.
- DVT procedure may have to reference other reports. Compliance (FCC, ATEX, UL, Etc) is one example.
- It is always a good idea to hold a design review after the DVT has been completed.
