A customer-facing review to confirm completed deliverables meet agreed acceptance criteria and to obtain formal acceptance. Done frequently (per item, iteration, or phase) after quality checks, resulting in accepted deliverables or change requests for rework.

Purpose & When to Use

• Confirm that completed deliverables meet the agreed scope and acceptance criteria.
• Obtain formal acceptance from the customer, product owner, or sponsor.
• Reduce disputes by basing acceptance on transparent, testable criteria.
• Use after internal quality verification is done and evidence is available.
• Apply at the end of a work item, iteration, phase, release, and at project handover.
• In adaptive approaches, perform frequent demos and accept items incrementally to accelerate value realization.

Mini Flow (How It’s Done)

• Prepare inputs: scope baseline or backlog, acceptance criteria, requirements traceability, and verified deliverables with quality records.
• Plan the review: invite decision-makers, define agenda, demo scripts, data sets, and logistics.
• Demonstrate or inspect the deliverable against each acceptance criterion.
• Capture results: pass, fail, or partial acceptance; note defects, gaps, and enhancement requests.
• Decide outcome: accept, accept with conditions, or not accept; confirm who has authority to decide.
• Record the decision and obtain formal sign‑off or product owner acceptance in the tool of record.
• If not accepted, create change requests or backlog items for rework, estimate impact, and plan the next validation.
• Update documents: requirements traceability, backlog, scope performance data, and lessons learned.
• Communicate outcomes and next steps to stakeholders and the team.

Quality & Acceptance Checklist

• Verified deliverables are available with evidence of completed quality checks.
• Acceptance criteria are clear, testable, and traced to requirements.
• Nonfunctional expectations (performance, security, usability, compliance) are evaluated.
• Interfaces, data, and end‑to‑end flow are demonstrated where relevant.
• Stakeholders with approval authority are present and prepared.
• Any variances, defects, or open questions are logged with owners and due dates.
• Formal acceptance decision, date, version, and conditions are recorded.
• Change requests or backlog updates are created for rework or enhancements.
• Scope and product information repositories are updated to reflect acceptance status.

Common Mistakes & Exam Traps

• Confusing Validate Scope (customer acceptance) with Control Quality (internal conformance checks).
• Waiting until the end to validate; in iterative or flow-based work, accept frequently to reduce risk.
• Accepting gold plating; extra features not in scope may be rejected and add cost.
• Lacking measurable acceptance criteria, leading to opinions instead of decisions.
• Assuming the project manager can sign off; acceptance must come from the authorized customer or product owner.
• Changing the baseline to match what was built; instead, raise change requests and follow change control.
• Skipping documentation of decisions and not updating traceability or backlog status.
• Using Validate Scope to fix defects; actual rework happens after approval and then is revalidated.

PMP Example Question

During a Validate Scope review, a deliverable fails one acceptance criterion. What should the project manager do next?

1. Ask the team to implement a quick workaround and re‑demo later today.
2. Record the defect and submit a change request or backlog item for rework, then schedule re‑validation.
3. Escalate to the sponsor to approve acceptance despite the failure.
4. Update the scope baseline to reflect what was actually delivered.

Correct Answer: B — Record the defect, raise a change request/backlog item for rework, and plan re‑validation.

Explanation: Validate Scope formalizes acceptance. When criteria are not met, document the variance and initiate change control or backlog updates for rework before another validation session.
