difference between verification and validation

Verification is the checking specifications as per requirements while validation is the checking of the software either it meets the customer’s requirements. Verification is a theoretical exercise designed to make sure that no requirements are missed in the design, whereas validation is a practical exercise that ensures that the product, as built, will function to meet the requirements. It should be noted that Method Validation vs. The main objective of Verification process is to make sure that the system being develop is as per the requirements and design specifications of the customer and if it deviates from it then make it correct in the development phase itself.
