When the budget at completion has shifted significantly and is higher than expected, it's important for the project manager to perform a root cause analysis. This involves investigating the factors and events that have led to the budget variance. By identifying the root causes, the project manager can address the underlying issues and take corrective actions to bring the project back on track. Adjusting stakeholder expectations and negotiating changes may be part of the response, but understanding the root causes is a crucial first step.

Selon le PMBOK après avoir identifié un problème il est recommandé ensuite de l'analyser avant toute autre chose. Donc la bonne réponse ici c'est le A. Ce n'est qu'après avoir compris le problème que l'une des solutions pourrait être de rencontrer les parties prenantes pour redéfinir le budget.

In this situation, the most effective course of action for the project manager is: D. Negotiate the project changes and adjust stakeholder expectations. Here's why the other options might not be optimal: A. Root cause analysis: While understanding the reasons behind the budget overrun is important, it doesn't address the immediate need to manage the increased cost and its impact on the project. B. Adjusting the original budget: Simply increasing the budgeted amount without addressing the reasons or negotiating with stakeholders might not be acceptable and could lead to further issues. C. Reviewing activity duration: Adjusting the timeline might be a potential consequence of budget variance, but it needs to be considered in conjunction with stakeholder negotiation and overall project feasibility. Negotiating project changes and adjusting stakeholder expectations are crucial steps in dealing with a significant budget overrun

Ans: D While I do agree, performing root cause analysis is important, but there is an issue at hand. It is already over budget. So what is more important is to negotiate and adjust expectations with stakeholders. So my answer would be D.
