Adding to what myton said above, the process of verification also is generally an internal check to make sure the product follows its initial design specification. A good product will stay true to these original regulations, specifications, and regulations that were originally mandated in the development phase. In addition, the verification process could also be performed in development, scale-up, and production phases.

As mentioned above, the main way to keep the verification process efficient and relatively painless to the company is to preform it early and often throughout the phases of the product life cycle. If a deviation from the original design specification is caught early in the life cycle of the product, both the monetary and time cost the company will incur to fix the issue will be minimized. In this way, a good verification process will help ensure critical timelines are met and that the overall progress of the product doesn’t fall behind schedule or over budget.
