Earned value Analysis Flashcards
PV
(Planned Value - Definition)
The authorized budget assigned to scheduled work
EV
Earned Value
EV = sum of planned value of completed work
AC
Actual Cost
of work completed to a point in time
BAC
Budget at Completion
Sum of all budgets for the work to be performed
CV (Cost Variance)
CV = EV - AC
Positive = Under planned cost
Neutral = On planned cost
Negative = Over planned cost
SV (Schedule Variance)
SV = EV - PV
Positive = Ahead of schedule
Neutral = On schedule
Negative = Behind schedule
VAC (Variance at Completion)
VAC = BAC - EAC
Positive = Under planned cost
Neutral = On planned cost
Negative = Over planned cost
CPI (Cost Performance Index)
CPI = EV / AC
Agile CPI = Completed Features value / Actual costs to date
Greater than 1.0 = Under planned cost
Exactly 1.0 = On planned cost
Less than 1.0 = Over planned cost
SPI (Schedule Performance Index)
SPI = EV / PV
SPI = Completed Features / Planned Features
SPI = ES / AT (Earned schedule / Actual time)
Greater than 1.0 = Ahead of schedule
Exactly 1.0 = On schedule
Less than 1.0 = Behind schedule
EAC (Estimate at Completion)
(when no change to plan, CPI is constant going forward)
EAC = BAC/CPI
EAC (Estimate at Completion)
(Atypical, cost deviated but expect to complete as planned)
EAC = AC + BAC - EV
EAC (Estimate at Completion)
(Flawed - plan no longer valid)
EAC = AC + Bottom-up ETC
EAC (Estimate at Completion)
(If both CPI and SPI influence the remaining work)
EAC = AC + [(BAC - EV)/(CPI * SPI)]
ETC (Estimate to Complete)
(assuming work proceeds on plan)
ETC = EAC - AC
ETC = (BAC - EV)/CPI
ETC (Estimate to Complete)
(reestimate remaining work from the bottom up)
ETC = Reestimate
