Which earned value management formula can help you determine how likely it is that you'll complete the program based on the amount of cash left in…

The To-Complete Performance Index (TCPI) is the specific Earned Value Management (EVM) metric used to determine the future cost efficiency required to complete the remaining work within a specific budget. It is calculated as the ratio of the work remaining (Budget at Completion - Earned Value) to the funds remaining (Budget at Completion - Actual Cost). This index directly answers how likely it is that the program will complete on budget by showing the level of performance that must be maintained. A TCPI greater than 1.0 indicates that future performance must be more efficient than originally planned.

A. Estimate at completion (EAC) is a forecast of the total program cost, not a measure of the performance efficiency needed to meet the budget.

B. Variance at completion (VAC) is a forecast of the amount of budget deficit or surplus at the end, not the required performance level.

D. Estimate to complete (ETC) is a forecast of the cost for the remaining work, not the efficiency required to execute that work.
