Earned Value Analysis (EVA) is a project management technique used to measure project
performance and progress. It integrates project scope, time, and cost data to provide accurate
forecasts of project performance.
Planned Value (PV): The estimated value of work planned to be done.
Earned Value (EV): The value of work actually completed.
Actual Cost (AC): The actual cost incurred for the completed work.
Using these metrics, EVA can help project managers assess whether they are ahead or behind
schedule and within or over budget.
