I think that the process of V& V, with the many years of re-evaluating, has become a lot more streamlined than it was previously. Although it can be cumbersome and add on time if issues come up, it is still in the best interest of the consumer (and companies) that it is followed. For instance, according to Bryan Larson, president of Toltec Ventures LLC:

“It is extremely important to consider VV early in the design stage when developing requirement specifications for the product. For example, adding test points on circuit boards, having accessible connectors, providing data storage/retrieval capabilities, and making products modular can enhance the ability to test a product, which saves time and money. VV costs can also be reduced if previously tested materials or coatings are used for the product. Clarity, conciseness, measurability, appropriate tolerances, accuracy, and testability can all impact the final design and overall manufacturability. These specifications also provide the acceptance criteria for later V&V activities.”

Therefore, if proper procedure is followed, the issue with timing should not become on that is too drastic.
