1

tE = (tO + tM + tP) / 3.”

Triangle method - Three-points estimating
tO = Optimistic
tM = Most likely
tP = Pestimistic

2

cE = (cO + cM + cP) / 3

Triangular distribution.
Depending on the assumed distribution of values within the range of the three estimates, the expected cost, cE, can be calculated using a formula.

3

cE = (O + 4M + P) / 6

Beta distribution.
Depending on the assumed distribution of values within the range of the three estimates, the expected cost, cE, can be calculated using a formula.

4

CV = EV – AC

Cost Variance
is the amount of budget deficit or surplus at a given point in time, expressed as the difference between earned value and the actual cost.

5

SV = EV – PV

Schedule Variance
is a measure of schedule performance expressed as the difference between the earned value and the planned value.

6

VAC = BAC – EAC

Variance at Completion

7

SPI = EV/PV

Schedule Performance Index
is a measure of schedule efficiency expressed as the ratio of earned value to planned value. It measures how efficiently the project team is accomplishing the work.

8

CPI = EV/AC

Cost performance index.
The cost performance index (CPI) is a measure of the cost efficiency of budgeted resources, expressed as a ratio of earned value to actual cost. It is considered the most critical EVA metric and measures the cost efficiency for the work completed.
