You are a project manager who is completing a project for another organization. The project you are managing will have phased deliverables throughout the project. Stakeholders are required to complete

The Statement of Work describes the products, services, or results to be supplied by the project but does not formally document the acceptance criteria used for validation.

The project scope statement includes the product scope description, project deliverables, exclusions, constraints, assumptions, and critically, the product acceptance criteria. According to PMBOK, this document provides the basis for future project decisions and for scope validation at phase gates. Stakeholders use it to confirm that deliverables meet the defined criteria before approving phase completion.

The project management plan is a high-level document that integrates subsidiary plans and baselines but does not itself contain the detailed product acceptance criteria.

A contract is a legally binding agreement between parties and may reference scope, but the specific acceptance criteria are documented in the project scope statement, not the contract.
