Verification -> Are we building product right?
Validation -> Are we building right product?

- Verification evaluates documents, plans, code,
requirements, and specifications.
- Validation, on the other hand, evaluates the product itself.

- The inputs of verification are checklists, issues lists,
walkthroughs and inspection meetings, reviews and meetings.
- The input of validation, on the other hand, is the actual
testing of an actual product.

- The output of verification is a nearly perfect set of
documents, plans, specifications, and requirements document.
- The output of validation, on the other hand is the
actual/perfect product.

=> Verification comes before Validation.

Verification ensures that the application complies to
standards and processes. This answers the question " Did we
build the right system? "

Eg: Design reveiws, code walkthroughs and inspections.

Validation ensures whether the application is built as per
the plan. This answers the question " Did we build the
system in the right way? ".

Eg: Unit Testing, Integration Testing, System Testing and
UAT.

Verification takes place before validation,and not
viceversa. Verification evaluates
documents,plans,code,requirement and
specification.Validation evaluates product itself.The
inputs for verification are checklist,issues
lists,walkthroughs and inspection meetings,reviews and
meetings.The input for validation is actual testing of an
actual product.The output for verification is nearly
perfect set of documents,plans,specificationand requirement
document. The output of validation is nearly perfect product
