The verification refers to the process that deals with evaluating the customer needs and “verifying” that what the scope is focused in on is based on the customer needs. Validation refers to the process of complying with regulations and specifications based on the process of verification. It seems that the verification precedes the validation because like I’ve mentioned in multiple times, the scope of the project, which ultimate comes down to the customer needs as stated in the verification is the most important aspect of the project.
