In the world of project management, what is the difference between "Perform Quality Control" process and "Verify Scope" process?

Quality Control versus 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”.

Example

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.

Perform Quality Control means to ensure the assured quality for the particular product deliverables by providing inspection & Test , avoiding rework which will help the company reputation.

Verify Scope -  The process which covers Quantity surveying, Comparision of revised BOQ a per latest approved drawing with the BOQ considered during tender, verifying the scope of supply, services as per agreed contract to complete the project in the Budgetted cost.

Hope the answer for the question

Validate scape is primarily concerned with acceptance of deliverables and 

control quality it is concerned of the correctness of the deliverables we always perform quality controll before validating the scope

Perfrom Quality Control ensures that the product of the project meets the quality standards & specifications.

Verifies Scope is physical inspection and formal acceptance of the interim deliverables by the customer during various stages of the project execution. This minimises the risk of changes in the later stages of the project and ensures the customer's final acceptance at the time of project closure.

1. Perform Quality Control is about ensuring that the deliverables meet the quality requirements defined in the Quality Management plan. Verify Scope is about formalizing the acceptance of deliverables.
2. Perform Quality Control belongs to Project Quality Management knowledge area, whereas Verify Scope is under Project Scope Management.
3. Perform Quality Control is focused on correctness of the deliverables whereas Verify Scope is focused on acceptance of deliverables.
4. Perform Quality Control is usually done by the Quality Control department, whereas Verify Scope is done by customer or sponsor. In Verify Scope process, the project manager holds several meetings with the customer or sponsor to review the deliverables to ensure that the deliverables are completed satisfactorily.
5. Perform Quality Control is usually done before Verify Scope, but these processes can be performed in parallel.
6. Validated deliverables, which are an output of Perform Quality Control, are an input to Verify Scope. The output of Verify Scope are Accepted Deliverables.
7. Both Perform Quality Control and Verify Scope are done as part of Monitor and Control process group, but Verify Scope can also be done at the end of each project phase to validate the deliverables of each phase.
8. Both Perform Quality Control and Verify Scope processes can result in change requests.

PQC  is the process for "monitoring specific project results to determine whether it comply with relevant quality standards and identifying ways to eliminate causes of unsatifactory performance"

SV is the process  by which the project manager gets the formalized acceptance of the completed project deliverables, successfully.

In practical, both these processes will help to define Quality of the final product.

Verify scope includes customer sign-off

Scope helps to refine the requirmenent and gets cusotmer signoff. while project qulaity ocntrol is to ensure at each step of the project that specifed standards and requirements are met.

from my view they are same but alitle difer is thier on the qualaty control is happening during the production while veriving scope is like check list is the product fit our requrement or not.

Quality control processes are to ensure that the approved quality is achieved.

verify scope processes are to ensure that the subject task is within the scope of the project as defined in the charter.

the diference is that do not verify quality control with out verifying the scope of work .
