The Integration Change Control process is a part of Project Integration Management knowledge area group. It falls under the Monitoring and Controlling process group. Monitoring and controlling is a process group or stage that starts when the project is in the executing stage. This process overlaps the executing stage. Monitoring and controlling consists of those processes performed to observe project execution so that potential problems can be identified in a timely manner and corrective action can be taken, when necessary, to control the execution of the project. The key benefit is that project performance is observed and measured regularly to identify variances from the project management plan. Monitoring and controlling includes: Measuring the ongoing project activities (where we are). Monitoring the project variables (cost, effort, ...) against the project management plan and the project performance baseline (where we should be). Identify corrective actions to properly address issues and risks (How can we get on track again). Influencing the factors that could circumvent integrated change control so only approved changes are implemented. In multi-phase projects, the monitoring and controlling process also provides feedback between project phases, in order to implement corrective or preventive actions to bring the project into compliance with the project management plan. What is Project Integration Management? Project Integration Management is one of the nine Project Management Knowledge areas. It comprises the following processes:

Develop Project Charter

Develop Preliminary Project Scope Statement

Develop Project Management Plan

Direct and Manage Project Execution

Monitor and Control Project Work

Integrated Change Control

Close Project

These processes occur throughout the project and are repeated quite often during the working of the project. They ensure that the various elements of the project are properly coordinated.

PERT, which means the Program Evaluation and Review Technique, is a duration estimating technique that uses the formula (O+(4M)+P)/6 for the optimistic, most likely, and pessimistic values for each work package. A PERT chart is a project management tool used to schedule, organize, and coordinate tasks within a project. PERT stands for Program Evaluation Review Technique, a methodology developed by the U.S. Navy in the 1950s to manage the Polaris submarine missile program. A PERT chart presents a graphic illustration of a project as a network diagram consisting of numbered nodes (either circles or rectangles) representing events, or milestones in the project linked by labeled vectors (directional lines) representing tasks in the project. The direction of the arrows on the lines indicates the sequence of tasks.

Answer option C is incorrect. This is the formula for the three-point estimate.

Answer options A and B are incorrect. These are not the valid formulas.

The critical path is the path in the project network diagram with the longest duration. In project management, a critical path is the sequence of project network activities which add up to the longest overall duration. This determines the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date (i.e. there is no float on the critical path). This project actually has two critical paths. Path ACGIJ takes 23 days. Path ACGHJ also takes 23 days. When Activity I decreases by three days the critical will still take 23 days to complete as Path ACGHJ remains a critical path.

Answer option A is incorrect. The duration of the critical path did not increase.

Answer option D is incorrect. The duration of the path ACGIJ will decrease to 20 days but the critical path will remain at 23 days.

Answer option B is incorrect. The critical path did not reduce to 17 days.

Activity F is on the critical path of ACFHK of 30 days. By adding five additional days to Activity F, the project will now take 35 days to complete.

Answer options C, A, and D are incorrect. These are not the valid answers.
