In accordance with the PMBOK® Guide (Project Integration Management), the Perform Integrated Change Control process 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.

Meetings are a primary tool and technique specifically used for this process, often referred to as Change Control Board (CCB) meetings.

Role of the CCB: The Change Control Board is a formally chartered group responsible for reviewing, evaluating, approving, deferring, or rejecting changes to the project.

Meeting Function: During these meetings, the impact of each change request is discussed. The board reviews the configuration management activities and determines the feasibility of the change in relation to the project ' s scope, schedule, cost, and risk baselines.

Decision Documentation: The outcome of these meetings is recorded in the Change Log as approved or rejected change requests.

Other Tools and Techniques: This process also utilizes Expert Judgment, Change Control Tools (manual or automated), and Data Analysis (including Alternatives Analysis and Cost-Benefit Analysis).

Analysis of Distractors:

A. Decomposition: This is a tool and technique used in Create WBS and Define Activities. It involves breaking down project scope and deliverables into smaller, more manageable components.

B. Modeling techniques: These are typically used in Develop Schedule (e.g., Schedule Network Analysis or S Curve) or Estimate Costs to simulate different scenarios.

C. Resource optimization: This is a tool and technique used in Develop Schedule and Control Schedule (such as Resource Leveling or Resource Smoothing) to adjust the schedule model based on resource demand and supply.
