Which process requires implementation of approved changes?

According to the PMBOK® Guide, the process of Direct and Manage Project Execution (referred to as Direct and Manage Project Work in newer editions) is where the actual work defined in the project management plan is performed to achieve the project ' s objectives.

Implementation of Changes: A key responsibility of this process is the implementation of approved changes. These changes can include:

Corrective Actions: To realign the performance of the project work with the project management plan.

Preventive Actions: To ensure the future performance of the project work is aligned with the project management plan.

Defect Repairs: To modify a nonconforming product or product component.

The Flow of Changes: Changes are identified in various monitoring and controlling processes, then they are reviewed and either approved or rejected in the Perform Integrated Change Control process. Once approved, they are sent back to the Direct and Manage Project Execution process to be physically carried out by the team.

Analysis of Other Options:

B. Monitor and Control Project Work: This process is concerned with tracking, reviewing, and reporting the overall progress of the project. It identifies the need for change but does not implement the work itself.

C. Perform Integrated Change Control: This is the " decision-making " process. This is where changes are approved or rejected. The act of approving happens here, but the implementation (the physical work) happens in Execution.

D. Close Project or Phase: This process involves finalizing all activities across all Project Management Process Groups to formally complete the project or phase. It is not the stage for implementing new changes to project deliverables.
