A project manager has recently reported a to-complete performance index (TCPI) of 1.0 to his project sponsor. Which of the following statements is correct?

The To-Complete Performance Index (TCPI) is a project management metric that provides an indication of the performance required to achieve the target or budgeted objectives for the remaining work in a project. It is calculated by dividing the remaining work (budgeted cost of work remaining, BCWR) by the remaining funds (budget at completion, BAC - earned value, EV). When the TCPI is equal to 1.0, it means that the project must continue performing at its current efficiency or productivity rate to complete within the budgeted objectives. In other words, the project needs to maintain the same level of performance to meet the planned budget and complete the remaining work within the allocated resources. If the TCPI is greater than 1.0, it indicates that the project needs to improve its performance and become more efficient to complete within the budget. Conversely, if the TCPI is less than 1.0, it suggests that the project is performing better than planned, and it has some flexibility in terms of cost or schedule.
