I’ve experienced a portion of the test and validation from my former co-op position, I wed to help to write the protocols and test cases for different systems and run it. I’ve run into a lot of testing that it didn’t pass special being a part of innovation center which is not a final product and is a cost center, not a profitable group. We used to work on an immature solution. So a lot of time we have to work with PMs to adjust the testing cases or try to come up with a solution for the found issues. Also, sometime we would outsource other company for testing special if it needs certifications.
