| Forecasting
118

119
Forecast are generated, updated and reissued based on...
Work performance data
120
What are EACs typically based on?
Actual costs incurred for work completed plus an estimate to complete (ETC) the remaining work

A manual bottom up summation by the project manager and project team
122
What is the equation for the bottom up EAC method ?
EAC=AC+Bottom-up ETC
123
This EAC method accepts the actual project performance to date (whether favorable or unfavorable) as represented by the actual costs, and predicts all future ETC Work will be accomplished at the budgeted rate.
EAC forecast for ETC work performed at the budgeted rate
EAC = AC + (BAC-EV)
124
If current actual performance is unfavorable, should someone assume actual performance will improve?
No only if they have risk analysis to support the idea that future performance will improve
125
This EAC method assumes that what the project has experienced to date can be expected to continue in the future. The ETC work is assumed to be performed at the same cumulative cost performance index (CPI) as that incurred by the project to date.
EAC forecast for ETC work performed at the present CPI.
Equation: EAC= BAC/CPL
126
In this EAC method the ETC work will be performed at an efficiency rate that considers both the cost and schedule performance indices.
EAC forecast for ETC work considering both SPI and CPI factors
Most useful when the project schedule is a factor impacting the ETC effort
Variations of this method rank the CPI and SPI at different values (80/20, 50/50, etc.)
