According to the PMBOK® Guide, the Perform Integrated Change Control process is the central hub where all change requests are reviewed, approved, or deferred. It is the process of reviewing all change requests; approving changes and managing changes to deliverables, project documents, and the project management plan; and communicating the decisions.
The primary purpose of this process is to provide a formal " Yes " or " No " to requested modifications.
The Output: Once a change request is processed by the Change Control Board (CCB) or the Project Manager, it becomes an Approved Change Request.
Next Steps: These approved changes are then sent to the Direct and Manage Project Work process to be implemented.
Other Related Outputs: This process also results in Change Logs (tracking the status of all changes) and Project Management Plan Updates (to reflect the new baseline if the change is approved).
A. Cost-benefit analysis: This is a Tool and Technique used during the process to help the CCB or Project Manager decide if a change is worth the investment. It is an analytical tool, not an output.
B. Updated project charter: The Project Charter is an initiating document. It is rarely, if ever, changed once the project begins. If the project ' s purpose or high-level objectives change so drastically that the charter needs updating, it usually signifies the start of a " new " project or phase rather than a standard change control output.
D. Multicriteria decision analysis: This is another Tool and Technique (specifically a data representation and decision-making tool) used to evaluate and rank change requests based on various factors like cost, schedule, and risk.
Identify Change: Stakeholder identifies a need.
Document: Create a formal Change Request (Input).
Impact Analysis: PM evaluates the impact on scope, time, and cost.
CCB Review: The board uses Decision Making (Tool).
Approved/Rejected Change Request: The final decision is reached (Output).
Implement: The team performs the work.
