Design verification can be conducted on the individual module or on the completed system under any conditions. Design validation follows successful design verification.Certain aspects of design validation can be accomplished during the design verification, but design verification is not a substitute for design validation.Design validation includes secondary or higher-level integration and system level testing.Design verification includes unit and primary integration level testing.Design Validation ask: Did you design the right product?.Design Verification ask: Did you design the product right?.Design Validation is used to define that the final design is as per the expectations of the user need.Design verification is used where the actual design output should be same as expected design output which satisfies the specifications of the product.These are different activities which are performed at every stage of development process. There are always misconceptions between verification and validation. Difference between Design Verification and Validation The final design output is a basis for device master record. Design output is the result of each design phase and at the end of total design effort. The goal of the design verification process during software development is ensuring that the designed software product is the same as specified.ĭesign input is any physical and performance requirement that is used as the basis for designing purpose. Design Verification is a method to confirm if the output of a designed software product meets the input specifications by examining and providing evidence.
