The To-complete performance index (TCPI) helps determine what aspect of a project?

• A. Future communication needs
• B. How to meet the budget at completion (BAC) or estimate at completion (EAC)
• C. Staffing requirements for remaining tasks
• D. Quality standards compliance

Answer: (B)

The To-complete performance index (TCPI) is a key performance metric used in project management to evaluate the cost performance required to complete the project within its approved budget. Specifically, TCPI indicates how efficiently the remaining budget needs to be spent to either stay within the Budget at Completion (BAC) or meet the Estimate at Completion (EAC).

When a project is assessed, the TCPI takes into account the work that is left to complete and the budget remaining, giving project managers a clear understanding of the cost control necessary to achieve financial targets by the end of the project.

Thus, option B accurately reflects the purpose of the TCPI as it directly correlates with cost management and performance tracking necessary to align project outcomes with financial goals. The other options do not pertain to the broader financial management aspect that TCPI addresses, which is strictly centered on ensuring that project expenditures align with budgetary constraints as the project progresses.
