Validation
Confirming that the product, service, or result actually satisfies customer and stakeholder needs and intended use. It is distinct from verification, which checks conformance to requirements and specifications.
Key Points
- Focuses on fitness for use and stakeholder expectations, not just specs.
- Often involves customer reviews, demonstrations, pilots, or user acceptance testing.
- Occurs at phase or project milestones and can be iterative throughout development.
- Outputs include formal acceptance, feedback, and change requests if needs are not met.
Example
A software team completes a feature set and invites end users to perform user acceptance testing. Users confirm the system supports their workflows and approve the release. This customer sign-off is validation.
