According to me, verification is about making something correctly whereas validation is about building a right product that sustains in the market for a longer period of time. The verification process is all about checking at regular interval if the designing/making of the product is being done properly or not with proper documentation of all the requirements needed for the product to be designed. whereas validation is done after the product is launched to the market. It is done by checking if it meets or fulfills the customer’s satisfaction or not.

What I think is a product may pass the verification process, but it may or may not pass the validation process.

Let’s take an example of a Medical device company. The company makes a proper MRI machine and that passes all the design criteria and has been produced with a well-defined manufacturing process which means that it has passed the verification process and it was launched successfully into the market. But it couldn’t be that successful in the market because it was not that user-friendly or cost-efficient. So it can’t be validated.
