A project manager was appointed to lead an already approved project.

The project manager is responsible for ensuring that the project remains aligned with its expected benefits and strategic objectives. If the benefits management plan contains questionable or outdated forecasted values, the correct course of action is to confirm that information with the sponsor and key stakeholders. This ensures alignment before execution continues.

Option B is premature and drastic.

Option C disregards the risk of misalignment with business value.

Option D assumes changes before confirming whether the original forecast is incorrect.
