The to-complete performance index (TCPI) is a measure of the cost performance that is required to be achieved with the remaining resources in order to meet a specified management goal, expressed as the ratio of the cost to finish the outstanding work to the remaining budget. A TCPI value equal to 1.0 means you are right on budget, and as long as you maintain the present cost performance index (CPI), you should not exceed the project budget. A TCPI value greater than 1.0 means you need to take a stricter cost management approach or you will exceed your budget at completion (BAC). A TCPI value less than 1.0 indicates you are within your budget and have done an excellent job of managing project costs. Details for Each Option: The project is within budget Correct. A TCPI is a measure of the cost performance that is required to be achieved with the remaining resources to meet a specified management goal, such as the BAC. It is expressed as the ratio of the cost to finish the outstanding work to the budget available. A TCPI of less than one indicates you are operating within your remaining budget. The project is over budget Incorrect. A TCPI of less than one indicates you are operating within your remaining budget. A TCPI of more than one would indicate that you are overspending and need to improve cost performance to finish the project within budget. The project is behind schedule Incorrect. A TCPI is a measure of cost performance rather than schedule performance. The project is ahead of schedule Incorrect. A TCPI is not a direct measure of the project's schedule performance.
