Validation
Confirmation by the provision of objective evidence that the requirements for a specific intended use or application have been fulfilled. (Are we building the right product?)

Validation prevents you from perfectly building the wrong thing.
We validate early with Prototypes. Don't write code until you have validated the concept with a wireframe or a mockup. It is cheaper to throw away a drawing than a codebase.
