2. Difference Between Verification And Validation
Verification Validation
1.Evaluate the Product to check
whether it meets Specific requirement
of the specific phase.
1 Evaluate the final product to check
whether it meets the business needs.
2.Check whether the product is built as
per the specified requirement and
design specification
2.Validation determines whether the
software is fit for user and satisfy the
business needs.
3.Checks ”are we building the
product right?”
3.Checks ”are we building the right
product?”
4.Verification is done without
executing the software
4. Validation is done with executing the
software
5.Involves all the Static Testing
techniques.
