The Validation or Verification test report is very significant in determining the success of a product. Once the Validation or Verification fails, it is important to go through the protocol step by step to find the factor that caused the failure. Although this may seem to be time consuming and waste in money, this would be the best process in fixing the issue. The regression test would be a faster route but there is no guarantee that all the factors are considered. As mentioned previously, there could be a specification that is overlooked and then affected by another specification. Even though redoing the entire Validation or Verification test report will take more time, it is a more accurate way of finding the issue at hand. With the regression test, if something is missed, then there could cause a defect in the product, which could possibly then harm someone using the product. In all cases, it is better to repeat the Verification and Validation protocols, if the test fails the first time around.
