Understanding TCPI
TCPI Fundamentals
What is TCPI?
The To-Complete Performance Index measures the cost performance efficiency needed to complete the remaining work within the budget. It's a forward-looking metric that tells you how efficiently you need to work to meet project targets.
TCPI Formula
Based on BAC: TCPI = (BAC - EV) ÷ (BAC - AC)
Based on EAC: TCPI = (BAC - EV) ÷ (EAC - AC)
Where BAC is used for ideal scenarios and EAC for realistic forecasts.
Interpretation Scale
• TCPI < 1.0: Ahead of schedule/budget
• TCPI = 1.0: On track
• TCPI > 1.0: Behind schedule/budget
• TCPI > 1.25: Critical performance issues
Practical Applications
Performance Monitoring
Use TCPI to track whether you're meeting efficiency requirements. A rising TCPI indicates worsening performance and the need for intervention.
Corrective Actions
When TCPI exceeds 1.0, implement process improvements, re-allocate resources, or adjust scope to bring performance back on track.
Decision Making
TCPI helps decide whether to continue with current approach, request additional budget, or consider project termination if targets become unachievable.
