During the execution phase of a construction project, the project manager notices that the cost incurred for the procurement of materials is consistently exceeding the planned budget. What is the BEST course of action for the project manager to take?
Negotiate a discount with suppliers to reduce the costs of materials.
Analyze the cause of the budget overrun, report to the governance board, and seek approval for budget adjustments.
Apply cuts to other areas of the project to counterbalance the overrun.
Ignore the variance as long as the overall project is within the approved budget.
