Validation checks that the product design satisfies or fits
the intended use (high-level checking), i.e., the software meets the user
requirements. This is done through dynamic testing and other forms of review.
Validation: Are we building the right product? (This
is dynamic process for checking and testing the real product. Validation always
involves with executing the code)
Validation: The process of evaluating software
during or at the end of the development process to determine whether it
satisfies specified requirements. [IEEE-STD-610]
It is a High level activity.
Performed after a work product is produced against
established criteria ensuring that the product integrates correctly into the
environment.
Determination of correctness of the final software
product by a development project with respect to the user needs and
requirements.
Validation ensures that the software operates as
planned in the requirements phase by executing it. Running predefined test
cases and measuring the output with expected results.
