Verification and Validation can be lumped together as V&V activities, however there is a key difference between the two stages. Verification is concerned with if the company designed the device right, while validation is concerned with if the company designed the right device. During verification, a company wants to ensure that the design of the product set by the customer, meets the customers needs. For example, Customer A wants a cauterizer designed to heat at a set temperature upon activation of the device. During verification, a company would verify that inputs of the customer requirements is embedded in the design of the cauterizer. Now, in regards to validation, this phase is concerned with if the company had designed the right device. The Validation phase ensures that there is objective evidence that the inputs requested by the customer, is fulfilled by the device. In my example given previously involving the design of a cauterizer, a validation test would include the execution of the designed device. A validation test for this device would be to ensure that the cauterizer heats up at the set temperature, consistently whenever activated by the end-user.
