According to the PMBOK® Guide, the process of Perform Integrated Change Control is uniquely identified as the process that is conducted from project inception through completion.
The Continuous Nature of Change: Change can happen at any time during a project ' s life cycle. Whether it is a change to a high-level requirement in the Project Charter (Inception) or a change to the final administrative closing procedures (Completion), every change must be processed through this specific framework.
Ultimate Accountability: The Project Manager is responsible for ensuring that no changes are made to the project baselines (Scope, Schedule, or Cost) without going through this formal process. This maintains the integrity of the " Performance Measurement Baseline. "
Relationship with Other Processes: While other monitoring and controlling processes (like Monitor and Control Project Work) are also ongoing, the PMBOK® specifically highlights Perform Integrated Change Control as the " inception to completion " process because it is the gatekeeper for all project modifications. It ensures that every change is reviewed, approved, or rejected in a coordinated fashion.
The Change Control Board (CCB): This process often involves a CCB, which is a formally chartered group responsible for reviewing, evaluating, approving, delaying, or rejecting changes to the project.
Comparison with Other Options:
Monitor and Control Project Work (A): This process focuses on tracking, reviewing, and reporting the overall progress to meet the performance objectives defined in the project management plan. While it occurs throughout the project, the " inception to completion " phrasing in PMI literature is most strictly associated with Change Control.
Perform Quality Control (B): This process (now Control Quality) is focused on monitoring and recording results of executing the quality activities to assess performance. It generally starts once the first deliverables are being produced, not necessarily at the absolute moment of inception.
Monitor and Control Risks (D): While risk management is continuous, it technically begins once the Identify Risks process is first executed during planning. Perform Integrated Change Control is viewed as the fundamental backbone that exists as soon as a project is authorized.
