EAC: What is Estimate at Completion?

The video tutorial explains the concept of Estimate at Completion (EAC) in Earned Value Management. It covers various methods to calculate EAC, including simple formulas and more complex approaches using Cost Performance Index (CPI) and Schedule Performance Index (SPI). The tutorial emphasizes the importance of assumptions in these calculations and discusses the difference between precision and accuracy. It also highlights the need for fresh estimates based on current project conditions.

What is the primary difference between Estimate at Completion (EAC) and Budget at Completion (BAC)?

• EAC is always higher than BAC.

• EAC includes only labor costs, while BAC includes all costs.

• EAC is the expected total cost at project completion, while BAC is the initial budget estimate.

• EAC is calculated before the project starts, while BAC is calculated during the project.

In the first method of calculating Estimate to Complete (ETC), what assumption is made about past problems?

• Past problems will worsen over time.

• Past problems are irrelevant to future work.

• Past problems will continue to affect future work.

• Past problems have been resolved and future work will follow the original plan.

What is the Cost Performance Index (CPI) used for in Earned Value Management?

• To calculate the initial budget.

• To adjust the Estimate to Complete based on past cost performance.

• To determine the schedule performance.

• To calculate the total project cost.

How is the Estimate at Completion (EAC) adjusted using the Cost Performance Index (CPI)?

• EAC is multiplied by the CPI.

• EAC is divided by the CPI.

• EAC is added to the CPI.

• EAC is subtracted from the CPI.

What additional factor is considered in the most sophisticated method of calculating EAC?

• Project duration

• Schedule Performance Index (SPI)

• Labor costs

• Material costs

Why might it be necessary to create a new Estimate to Complete (ETC) from scratch?

• Because the budget was reduced.

• Because the project manager changed.

• Because past assumptions may no longer be valid.

• Because the project scope has increased.

What is the main reason for having multiple methods to calculate EAC and ETC?

• To confuse project managers.

• To account for different assumptions about project performance.

• To ensure all projects have the same cost.

• To make project management more complex.
