FORMULAS Flashcards
cE can be calculated with this triangular formula.
Triangular Distribution [cE = (cO + cM + cP) / 3]
A measure of schedule performance expressed as the amount the project is ahead or behind the planned delivery date.
Schedule Variance (SV = EV - PV)
The amount of budget deficit or surplus at a given point in time, expressed as the difference between earned value and the actual cost.
Cost Variance (CV = EV - AC)
A measure of schedule efficiency expressed as the ratio of earned value to planned value. A value less than 1.0 indicates less work was completed than was planed. A value greater than 1.0 indicates more work was completed than was planned.
Schedule Performance Index (SPI = EV/PV)
A measure of the cost efficiency of budgeted resources expressed as a ratio of earned value to actual cost. A value of less than 1.0 indicates a cost overrun for work completed. A value greater than 1/0 indicates a cost underrun of performance to date.
Cost Performance Index (CPI = EV/AC)
EAC forecast for remaining project work performed at the budgeted rate.
EAC = AC + (BAC - EV)
EAC forecast for remaining project work performed at the present CPI.
EAC = BAC / CPI
The measure of the cost performance based on the BAC that is required to be achieved with the remaining resources in order to meet a specific management goal, expressed as the ration of the cost to finish the outstanding work to the remaining budget. The efficiency that must be maintained in order to complete on plan.
<1=Easier to complete; 1=Same to complete; >1=Harder to complete
To-Complete Performance Index
TCPI = (BAC - EV) / (BAC - AC
A projection of the amount of budget deficit or surplus expressed as the difference between the budget at completion and the estimate at completion
Positive = Under Budget; Neutral=On planned budget; Negative=Over Budget
Variance at Completion (VAC = BAC - EAC)
The measure of the cost performance that is required to be achieved with the remaining resources in order to meet a specific management goal, expressed as the ration of the cost to finish the outstanding work to the remaining budget. The efficiency must be maintained in order to complete the current EAC.
<1=Easier to complete; 1=Same to complete; >1=Harder to complete
To-Complete Performance Index
TCPI = (EAC - EV) / (EAC - AC
The expected cost to finish all of the remaining project work.
Estimate to Complete
ETC = EAC - AC
Schedule Variance
SV = EV - PV
Schedule Performance Index
SPI = EV / PV
Cost Variance
CV = EV - AC
Cost Performance Index
CPI = EV / AC
