Know where every project stands

Earned value is calculated daily from the approved schedule, completed quantities and actual cost. You see the warning signs while there is still time to act, for one project or across all of them.

Are we over budget?
Cost performance (CPI) compares the value of work done with what it actually cost.
Are we behind schedule?
Schedule performance (SPI) compares the work done with the work planned.
What will it cost in the end?
The estimate at completion (EAC) forecasts the final cost at current performance.
What will it take to recover?
To-complete indices show the pace needed to finish on budget and on time.

All the standard earned-value measures are included, with daily and monthly views.
