|
Expected Value (EV)
|
(O+4M+P)/6
O= Optimistic M= Most Likely P= Pessimistic |
|
|
Schedule Performance Index (SPI)
|
SPI = EV/PV
EV = Earned Value PV = Planned Value <1 bad =1 Right on >1 Good |
|
|
Cost Performance Index (CPI)
|
CPI = EV/AC
EV = Earned Value AC = Actual Cost <1 Bad =1 Right on >1 Good |
|
|
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 |
|
|
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 to x EF = Early Finish |
|
|
Standard Deviation (σ) of a single activity
|
σ=(P-O)/6
P = Pessimistic O = Optimistic |
|
|
Standard Deviation Variance for a Single Activity (σ)^2
|
σ^2 = ((P-O)/6)^2
P = Pessimistic O = Optimistic |
|
|
Standard Deviation for series of activities
|
√∑σ^2 = √sum((P-O)/6)^2
O=optimistic P=pessimistic |
|
|
Project Variance (V)
|
V = Total σ = Total (P-O)/6
P=Pessimistic O=Optomistic |
|
|
Project Standard Deviation
|
=√V
V=Project Variance |
|
|
Average (Mean)
|
(O+M+P)/3
O=Optimistic M=Most Likely P= Pessimistic |
|
|
Mutually Exclusive Path Convergence
|
multiply all the % between milestone A and milestone B
|
|
|
Schedule Variance (SV)
|
SV = EV - PV
EV = Earned Value PV = Planned Value - always bad =0 right on + always good |
|
|
Cost Variance (CV)
|
CV = EV - AC
EV = Earned Value AC = Actual Cost - always bad =0 right on + Always good |
|
|
Variance At Completion (VAC)
|
VAC = BAC - EAC
BAC = Budget at completion EAC = Estimate at completion |
|
|
Cost of Quality (COQ)
|
COQ = EFTW + COPQ = POC +PONC
EFTW = Essential 1st Time Work COPQ = Cost of Poor Quality POC = Price of Conformance PONC = Price of Non-conformance |
|
|
Present Value (PV)
|
PV = FA / (1+ i^n)
FA = Future Amount i = interest rate n = number of years |
|
|
Straight-line Depreciation
|
= Asset Cost / Useful Life
|
|
|
Double Declining Balance
|
= 2 x ((Asset Cost - Accumulated Depreciation)/useful life)
|
