Method 1 - Comparison of CV to VAC
Cum Cost Variance (|CvCum|(-0)|[z1]|)
VAC (|Vac|(-0)|[n1]|)

Method 2 - Comparison of CPI to TCPI-EAC
CPI (|CpiCum|(-0)|([z3])|)

TCPI-EAC

 (|TcpiLre|(-0)|([z3])|)
Comparison of CPI to TCPI-EAC (|CpiToLre|(-0)|([z3])|)

Method 3 - Compare EAC to Calculated Forecasts
Contractor's EAC (|Lre|([z1])|)
wInsight Independent Calculated Forecasts
  • CPI (3 period average)
(|MovAvg3|([z1])|)
  • CPI (6 period average)
(|MovAvg6|([z1])|)
  • Cumulative CPI
(|CumCpiFc|([z1])|)
  • Weighted Cost Schedule
(|WtCostSch|([z1])|)
  • CPI6*SPI
(|Micom|([z1])|)
  • CPI*SPI
(|CpiSpi|([z1])|)
Cumulative Performance
  • Cumulative CPI
(|CpiCum|([z1])|)
  • Cumulative SPI
(|SpiCum|([z1])|)
Compare the EAC to range of statistical EACs. If the EAC is outside the range of calculated EACs, it will be flagged as optimistic or conservative.
Review past performance efficiencies, Cum CPI and Cum SPI. These are used to calculate the calculated EACs.
Method 4 - Compare EAC to Regression Forecasts
Contractor's EAC (|Lre|([z1])|)
Linear Regression (|LinRegr|([z1])|)
Evaluate the EAC against the linear regression formula. Note that this is not a curvilinear function, but a straight line projection.
