Understanding EAC Calculations
EAC Formulas Explained
EAC = BAC / CPI
Used when current cost variance is expected to continue. Assumes that the remaining work will be completed at the same cost efficiency as the work completed to date.
EAC = AC + (BAC - EV)
Used when current variance is considered atypical and future work will be completed at the planned rate. Best when the variance was caused by a one-time event.
EAC = AC + ETC
Used when a new bottom-up estimate is created for the remaining work. Provides a fresh estimate based on current conditions and lessons learned.
TCPI Analysis
TCPI based on BAC
Calculates the efficiency needed to complete the project within the original budget. TCPI > 1 indicates that improved performance is required to meet the original target.
TCPI based on EAC
Calculates the efficiency needed to complete the project at the current EAC forecast. This provides a more realistic target based on current project performance.
Risk Assessment
TCPI values help assess project risk. Higher TCPI values indicate greater difficulty in meeting project objectives and may require intervention.
EAC Best Practices
Formula Selection
Choose the appropriate EAC formula based on project conditions and variance patterns.
Regular Updates
Update EAC calculations regularly to reflect current project performance and conditions.
Data Accuracy
Ensure accurate and timely data collection for reliable EAC calculations and forecasts.
Stakeholder Communication
Communicate EAC results clearly with explanations of assumptions and implications.
Scenario Planning
Use multiple EAC formulas to create different scenarios for better risk management.
Corrective Actions
Use TCPI analysis to determine necessary corrective actions to meet project objectives.
