How does verify scope differ from validate scope?

Verify scope and validate scope are two different project scope management processes:

• Verify Scope (verification of work) is the process of formally checking and confirming that the completed work meets the requirements and specifications. It usually involves inspections, reviews, and testing of results to ensure that the product complies with the technical specifications.

• Validate Scope (validation of work) is the process of formally accepting the project deliverables by the customer or stakeholders. It assesses whether the final product meets the expectations and requirements of the customer, and a decision is made to accept it.

In simpler terms, verify scope is internal quality control and compliance, while validate scope is external confirmation and acceptance of the project results.
