## Cost Management

Question | Answer |
---|---|

Planned Value PV | FV/(1+i)^n |

Cost Variance CV | EV - AC; (-)=overbudget (+)=within budget |

Schedule Variance SV | EV - PV; (-) = behind schedule, (+) = on schedule |

Cost Performance Index CPI | EV/AC; <1 over budget, >1=under budget |

Schedule Performance Index SPI | EV/PV; <1 behind, >1 ahead, =1 on schedule |

## Earned Value Management

Question | Answer |
---|---|

Estimate At Completion (variances ATYPICAL) EAC | AC + (BAC - EV) |

Estimate At Completion (TYPICAL) (assume same rate of spending to continue) EAC= | BAC/CPI |

Estimate At Completion (Bottom Up) (most accurate, time consuming) | AC + ETC |

Estimate At Completion (Hard Date/Worst/Continue) (Assume current cost/sched. perf. to continue - what will it cost me to make this date) | AC + [(BAC-EV)/(CPI * SPI)] |

Estimate To Completion (Expected cost of work remaining) ETC | EAC - AC |

Variance At Completion (-) Over Budget, (+) Under Budget VAC= | BAC - EAC |

To Complete Performance Index (Original Budget Attainable)(Cost Performance rate needed to complete within budget) TCPI | (BAC-EV)/(BAC-AC) |

To Complete Performance Index (Original Budget NOT Attainable) (Assumes original budget cannot be achieved)TCPI | (BAC - EV)/(EAC-AC) |

ROM | -25% to +75% |

Definitive Estimate | -5% to +10% |
