Which activity focuses on ensuring that project deliverables meet specified requirements?

The activity that focuses on ensuring that project deliverables meet specified requirements is verification. Verification is the process of evaluating products, services, or systems to determine whether they comply with the specified requirements at a particular stage of the project. It is about checking whether the deliverables are built correctly according to the requirements outlined during the requirements analysis phase.

Verification typically includes activities such as reviews, inspections, testing, and analysis to confirm that the products meet the necessary specifications and standards. The key aspect of verification is that it aims to prove that the outputs fulfill the input specifications; that is, "Are we building the product right?"

While validation deals with confirming that the right product is built to meet the needs and expectations of the stakeholders, verification is specifically concerned with whether the deliverables align with the specified requirements. The requirements analysis phase focuses on gathering and defining the needs, while integration involves combining various components into a complete system. Thus, verification is distinctly focused on checking compliance with the specified criteria for deliverables.
