I completely agree with the points mentioned above. An effective product is the fruit of good design controls and other properly implemented steps. Just as every ingredient is important, a good verification process ensures that a product will work based on its original design. It is also implemented to see whether there are other effects of the design or flaws and problems. This ensures that the bulk product that will be released for consumer use will not hurt them. This also reduces the possibility of additional cost which can stem from regulatory costs and litigation. Verification allows for scientists to see if their product performs as intended and also, any unforeseen side effects that it may have. one way to have a good verification process is to make sure that every detail agrees with the design specification and to check the progress every step of the way.
