|
Standard Deviation for series of activities
|
√∑σ^2=√sum((P-O)/6)^2
O=optimistic P=pessimistic |
|
|
Straight Line Depreciation
|
=Asset Cost/Useful Life
|
|
|
Standard Deviation Variance for a single activity (σ)^2
|
(σ)^2 = ((P-O)/6)^2
|
|
|
Average (mean)
|
(O+M+P)/3
O=optimistic P=pesimistic M=most likely |
|
|
Project Variance
|
V = Total σ = Total (P-O)/6
O=optimistic P=pesimistic |
|
|
Cost Variance (CV)
|
CV = EV-AC
EV= Earned Value AC= Actual Cost -ve value bad =equal value right on track +ve value always good |
|
|
Double declining Balance
|
2x((Asset cost - Accumulated Depreciation)/useful life)
|
|
|
Variance At Completion (VAC)
|
VAC = BAC - EAC
BAC = Budget at completion EAC = Estimate at completion |
|
|
Total Slack (TS)
|
TS = LF-EF = LS-ES
LF = late finish EF = early finish LS = late start ES = early start TS = 0 is the critical path |
|
|
Mutually exclusive path convergence
|
Simple multiply all the % between milestone A & milestone B
|
|
|
Project Standard Deviation
|
= √V
V = Project variance |
|
|
Cost of Quality (COQ)
|
COQ = EFTW+COPQ=POC+PONC
EFTW = essential 1st time work COPQ = cost of pooer quality POC = price of conformance PONC = price of non conformance |
|
|
Cost Performance Index (CPI)
|
CPI = EV/AC
EV = earned value AC = actual cost <1 bad =1 right on track >1 always good |
|
|
Free Slack (FS)
|
FS of x = Ex (of x+1) - EF (of x) -1
ES (of x+1) = Early start of the earlies succeeding activity of x EF = early finish |
|
|
Expected Value (EV)
|
(O+4M+P)/6
O= optimistic M= most likeley P= pessimistic |
|
|
Schedule Performance Index (SPI)
|
SPI = EV/PV
EV = earned value PV = planned value <1 bad =1 right on track >1 always good |
|
|
Schedule Variance (SV)
|
SV = EV-PV
EV = earned value PV = planned value -ve value bad = eqaul value menas right on track +ve value always good |
|
|
Present Value (PV)
|
PV = FA/(1+i^n)
FA = Future Amount i = interest rate n = number of years |
