Hi, When you do a project for a client, you would have gathered the requirements. when you started building software you need to check it whether you software meets the requirements of client. Verify the requirements against the software you develop. The validation involves with the business activities and validate them by testing.

Hi David, The standard definition is Verification: Are we building the right product? Validation: Are we building the product right?

Hi David, Verification: This verifies whether the product is done according to the specification? The process of determining whether of not the products of a given phase of the software development cycle meet the implementation steps and can be traced to the incoming objectives established during the previous phase. The techniques for verification are testing, inspection and reviewing. Validation: This checks whether the product meets the customer requirement? The process of evaluating software at the end of the software development process to ensure compliance with software requirements. The techniques for validation is testing, inspection and reviewing. Verification takes place before validation. Verification evaluates documents, plans, code, requirements and specifications. Validation evaluates the product itself.Verification is a review without actually executing the process while validation is checking the product with actual execution. For instance, code review and syntax check is verification while actually running the product and checking the results is validation. Thanks
