Validate Scope is about acceptance: the customer or sponsor reviews completed, verified deliverables and formally accepts them. It is distinct from Control Quality — quality control checks correctness internally, while scope validation secures external acceptance against the agreed requirements.

Validate Scope: key inputs and outputs — The key inputs feeding Validate Scope and the deliverables it produces — full ITTOs are listed below.

Inspection and review against acceptance criteria drive the decision. Doing this periodically, not just at the end, catches misunderstandings early and reduces the risk of a big rejection late in the project.

Common pitfalls. Confusing validation (customer acceptance) with verification (quality control); deferring all acceptance to the end; unclear acceptance criteria that make sign-off subjective; and accepting deliverables informally with no record.
