Verification and Validation

What it actually means

The paired questions asked of every product: verification — did we build it right (does it meet its requirements)? — and validation — did we build the right thing (does it serve the actual need in the actual environment)? A system can pass every verification and still fail validation; that gap is where requirements errors hide until fielding.

Where you'll meet it

Test planning, requirements management, and the vocabulary of every review.
