Quality Control vs Verify Scope

Quality Control vs Verify Scope

If you enjoyed reading this post, check out all of our post on PMP Concepts Learning Series.

Designed to help those that are preparing to take the PMP or CAPM Certification Exam, each post within this series presents a comparison of common concepts that appear on the PMP and CAPM exams.

Quality Control vs Verify Scope

While most people understand the concept of quality control, differentiating QC from the verify scope process may be a bit more difficult. Both processes are monitoring and controlling processes and both involve the evaluation of the project deliverables.

Quality Control

The perform quality control (QC) process evaluates the project results (outputs, deliverables) to ensure they comply with quality standards that were defined in the quality management plan. The QC process also identifies ways to eliminate causes of unsatisfactory results and validates that approved change requests have been implemented as approved.

QC must be conducted prior to the verify scope process and the perform quality assurance (QA) process (where the project processes and results will be audited and evaluated for continuous process improvement actions).

Think of QC as the internal quality check of the products or deliverables prior to giving them to the customer or end-user.

The key outputs from QC are the “validated deliverables”

Verify Scope

The verify scope process secures formal acceptance of the completed project deliverables from the customer, end-user, or requesting party. Verifying scope includes reviewing the deliverables with the customer to ensure that they are completed satisfactorily in order to receive formal acceptance of the deliverables.

Think of verify scope as the quality check / user acceptance testing.

The key outputs from verify scope are the “accepted deliverables”.


As part of my project management requirements, I need to produce a weekly project performance report.

When I check the data and figures within my performance report to ensure they are correct, I am performing quality control.

When I provide the performance report to my sponsor for her approval, I am performing verify scope.


While both QC and verify scope are monitoring and controlling processes associated with the review and approval of the deliverables, QC is the “internal” check that results in “validated deliverables”, followed by verify scope, the “external” check that results in “accepted deliverables”.

    The pmbok is very confusing. Thank you for providing examples in clear and concise language. I don’t know if you are still posting to this site, but grateful I found it.

    Thank you for demystifying the integration of processes with these comparisons. I have created a way to remembering this now, “Quality Control comes before the VIP who accepts the deliverable.” QC–>Validate (with the customer, aka VIP) –> Accepted deliverable. At times there are different angles, within integration, so I hope that I got it now when it comes to interpreting a test question. Greatly appreciated – thanks again!
