Which of the following measurements is the value of the work actually finished?

Earned value (EV) is the value of the work that’s actually been completed. Planned value (PV) is the budgeted amount planned for work to be completed during a given time period, and actual cost (AC) is the cost of work completed during a given time period. EAC is a forecasting technique that is an estimate of the expected total cost of a work component.
Earned value (EV) is the value of the work that has actually been completed. It is calculated by multiplying the budgeted cost per unit of work by the number of units of work that have been completed.
The EV is a measure of how much progress has been made on a project. It can be used to track the project's progress and to identify potential problems. If the EV is less than the planned value (PV), then the project is behind schedule. If the EV is more than the PV, then the project is ahead of schedule.
The EV can also be used to calculate the project's budget performance index (CPI). The CPI is a measure of how efficiently the project is being managed. A CPI of 1 means that the project is on budget. A CPI of less than 1 means that the project is over budget. A CPI of more than 1 means that the project is under budget.
The EV is an important metric for project managers to track. It can be used to monitor the project's progress, identify potential problems, and make informed decisions about how to manage the project.
