Validation and Verification

Validation

In the waterfall model, validation operations provide feedback from Specification to Requirements and from Implementation/unit testing to Specification.

Validation can be thought of as "Are we building the righy system?"

Verificatiom

Verification operations provide feedback from Integration/ system testing to Implementation/unit testing, and from operations/maintenance back to Integration/system testing.

Verification asks "Are we building this system right/correctly?"
