After establishing a cost baseline and the appropriate cost management plan for a complex hybrid project, the project is still being challenged with…

The project manager's responsibility is to monitor and control the project's performance against established baselines. When budgetary variations occur, the correct procedure, as defined in the cost management plan, is to track and analyze these variances. The project manager must then collaborate with key stakeholders to understand the root causes and determine the appropriate course of action, which may include adjusting the budget, scope, or schedule through the formal integrated change control process. This approach ensures that decisions are made transparently and are aligned with the project's overall objectives, which is critical in any project methodology, including hybrid ones.

B. This is an arbitrary rule. The decision to approve a budget variation should be based on a thorough analysis of the change request, not solely on a favorable Cost Performance Index (CPI).

C. Automatically rejecting all variations is counterproductive. Legitimate changes may be necessary to address risks or add value, and a rigid refusal to consider them undermines the project's ability to adapt.

D. Automatically approving variations leads to uncontrolled spending and scope creep (gold plating). All changes must be evaluated through a formal change control process to assess their impact.

Section 2.7

Measurement Performance Domain (p. 133): This domain emphasizes the importance of assessing project performance and taking appropriate action to maintain acceptable performance. It states

"Effective measurement includes tracking progress and forecasting so the project team and stakeholders know where the project is and where it is headed." This supports the "track budget variations" part of the correct answer.

Section 2.1

Stakeholder Performance Domain (p. 41): This domain highlights that "Stakeholder engagement entails working in collaboration with stakeholders to... make decisions." This supports the "work with the key stakeholders to adjust" part of the correct answer.

Section 7.4

Control Costs (p. 257): The definition of this process is "monitoring the status of the project to update the project costs and managing changes to the cost baseline." The entire process involves analyzing the relationship between the consumption of funds and the work being accomplished

which directly aligns with tracking and managing variations.

Section 7.4.2.2

Data Analysis (p. 261): Variance analysis is a key technique within the Control Costs process. It is used to explain the cause

impact

and corrective actions for cost variances

which is precisely what the project manager should do.
