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 = LFEF =LSES
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=(PO)/6
P = Pessimistic O = Optimistic 

Standard Deviation Variance for a Single Activity (σ)^2

σ^2 = ((PO)/6)^2
P = Pessimistic O = Optimistic 

Standard Deviation for series of activities

√∑σ^2 = √sum((PO)/6)^2
O=optimistic P=pessimistic 

Project Variance (V)

V = Total σ = Total (PO)/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 Nonconformance 

Present Value (PV)

PV = FA / (1+ i^n)
FA = Future Amount i = interest rate n = number of years 

Straightline Depreciation

= Asset Cost / Useful Life


Double Declining Balance

= 2 x ((Asset Cost  Accumulated Depreciation)/useful life)
