Scope Planning

Correct Answer: Evaluate the impact of the change on the project’s timeline, costs, and resources before presenting it to the change control board for a decision.

The best course of action for the project manager is to evaluate the impact of the proposed change on the project's timeline, costs, and resources before presenting it to the change control board for a decision. This approach allows the project manager to thoroughly assess the feasibility of incorporating the change while considering the project's constraints. By analyzing the potential impact, the project manager can provide the change control board with the necessary information to make an informed decision. Rejecting the proposed change outright may strain the relationship with the key stakeholder and potentially miss an opportunity to enhance the project's impact. Accepting the change without proper evaluation could jeopardize the project's success by overextending resources and compromising the timeline and budget. Proposing an alternative solution without first assessing the impact of the original change request may not fully address the stakeholder's concerns and could still affect the project's scope.

Correct Answer: Work Breakdown Structure (WBS)

The best tool for decomposing project deliverables into smaller, more manageable components is the Work Breakdown Structure (WBS).

The WBS is a hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables. It organizes and defines the total scope of the project, and represents the work specified in the current approved project scope statement.

This tool is specifically designed to break down complex projects into smaller, more manageable parts, which is exactly what the project manager needs in this situation where the scope definition lacks sufficient detail.

The Project Scope Statement is not the correct answer because it is a high-level document that describes the project's deliverables and requirements. While it's an important document, it doesn't provide the level of detail needed to guide execution effectively.

The Requirements Traceability Matrix is used to track requirements throughout the project lifecycle. While useful, it doesn't help in decomposing deliverables into smaller components.

The Stakeholder Engagement Plan with detailed deliverable descriptions is not the right tool for this purpose. While it may contain some information about deliverables, its primary focus is on managing stakeholder expectations and involvement, not on breaking down the project work.

Correct Answer: Perform a risk reassessment and update the risk response plan

When the raw material prices increase, the projected cost of the construction project changes, presenting a new risk to the project. The correct action is to 'Perform a risk reassessment and update the risk response plan'. By doing so, the project manager can identify and evaluate the new risk, formulate new strategies to mitigate it, and update the risk response plan accordingly, thereby ensuring the project remains within scope. As for the incorrect options, 'Ignoring the price increase' is not a feasible solution because it would result in potentially excessive overspending and could lead to the project going over budget. 'Changing the project scope without updating the plan' is equally improper, as it violates basic project management principles, which demand any changes to the project scope be reflected in the project plan. 'Asking suppliers to reduce prices' may not be feasible or effective, particularly in a market environment where prices are rising, as it is in this case.
