According to the PMBOK® Guide, ensuring that requirements are met and validated involves a flow from planning to execution and finally to formal acceptance.

Plan Scope Management: This is the foundational process. It provides guidance and direction on how scope will be managed throughout the project. The output is the Scope Management Plan, which acts as a " rulebook " for how the team will handle product requirements.

Collect Requirements: This is the active elicitation phase. It provides the basis for defining the product scope and project scope. Without this process, the project manager cannot know what " success " looks like for the Product Owner.

Control Quality: Often confused with Validate Scope, Control Quality is an internal process. It focuses on the correctness of the deliverables and ensures they meet the technical requirements. It is usually performed before Validate Scope to ensure the team isn ' t showing the customer a " broken " product.

Validate Scope: This is the process where the Product Owner or Customer officially signs off on the deliverables. The key benefit of this process is that it brings objectivity to the acceptance process and increases the probability of final product acceptance by validating each deliverable.

Crucial Distinction: A common point of failure in professional exams is the difference between Control Quality and Validate Scope.

Control Quality is about Correctness (Meeting technical specs; internal).

Validate Scope is about Acceptance (Meeting stakeholder needs; external).

Per PMI standards, these processes work in tandem to ensure that the final product delivered matches the original intent documented during the " Collect Requirements " phase.
