According to the PMBOK Guide, the Perform Integrated Change Control process is the process of reviewing all change requests; approving changes and managing changes to deliverables, organizational process assets, project documents, and the project management plan; and communicating the decisions.
* Role of the Project Management Plan: The Project Management Plan is a primary input because it contains the baselines (scope, schedule, and cost) and the change management plan. To evaluate the impact of a change request, the Change Control Board (CCB) or the project manager must compare the request against the established plan to see how it affects the project ' s objectives.
* Specific Components Used:
* Change Management Plan: Provides the direction for managing the change control process and documents the roles and responsibilities of the Change Control Board (CCB).
* Configuration Management Plan: Describes how the items of the project are identified and defined.
* Scope, Schedule, and Cost Baselines: Used to assess the impact of changes on the project ' s overall performance.
Comparison with other options:
* A. Expert judgment: This is a Tool and Technique used during the process to evaluate the technical and management implications of the change, not an input.
* B. Seller proposals: These are typically inputs to the Conduct Procurements process, where the organization evaluates bids from potential vendors.
* C. The project charter: This is the output of the Develop Project Charter process and is used as an input to the Develop Project Management Plan and Identify Stakeholders processes. It is generally too high- level to serve as the functional baseline for Integrated Change Control.
