External stakeholders typically require performance metrics to understand the status of a project. Earned value is a proven methodology to measure project performance objectively. Earned Value in terms of schedule (D) and cost (E) offers valuable insights on how well the project is adhering to its baseline plans. D: Earned Schedule (EV vs. Planned Value) shows schedule adherence. E: Earned Cost (EV vs. Actual Cost) shows cost efficiency. Options A and C are portfolio-level metrics, not typically reported by project managers. Option B is vague and not part of standard EVM practice.
