Q U A L I T Y
-------------
CoQ = ( ( Review Efforts + Test Efforts + Training Efforts + Rework Efforts + Efforts of Prevention) / Total Efforts) x 100 %

PERT = O + 4ML + P
--------------

MEAN -> Average

MODE -> The "most found" number

RANGE -> Largest - Smallest Measure.

MEDIUM -> No in the middle or avg. of 2 middle Nos

STD. DEV. OF TASK = P - O
____________

TASK VAR. = (P - O) 2 = Std. Dev ^ 2

_____________
CP STD. DEV. = √ σ² + σ² + σ²


SIGMA 1 = 68.26
2 = 95.46
3 = 99.73
6 = 99.99

Channels of Communication
-------------------------
COMM = (N2 - N) / 2 = (N x (N - 1)) / 2

PV = F V .

(1+r)�

FV = PV x (1+r)

NPV = S ( PV + PV + PV + PV )

Cash Flow = Cash Inflow - Cash Outflow

Discounted Cash Flow = CF x Discount Factor

ARR = S Cash Flow / No. of Years

ROI = (ARR / Investment) * 100 %

BCR = Benefits / Cost

Exp. Value = Probability % x Consequence $


Class of Estimates

-------------------
Definitive +5%

Capital Cost +10-15%

Appropriation +15-25%

Feasibility +25-35%

Order of Magnitude > +35%


Contract Incentives
--------------------
Savings = Target Cost - Actual Cost

Bonus = Savings x Percentage

Contract Cost = Bonus + Fees

Total Cost = Actual Cost + Contract Cost

---------------------------------------------
PV (Present Value) = BCWS (Budgeted Cost of Work Schedule)

EV (Earned Value) = BCWP (Budgeted Cost of Work Performed)

AC (Actual Cost) = ACWP (Actual Cost of Work Performed)

CV = EV - AC

CPI = EV / AC (efficiency)

SV = EV - PV

SPI = EV / PV

ETC = BAC - EV or (BAC - EV) / CPI

EAC = AC + ETC

EAC = BAC / CPI

VAC = BAC - EAC

% COMPLETE = EV / BAC x 100

% SPENT = AC / BAC x 100

CV% = CV / EV x 100

SV% = SV / PV x 100

The PMP exam is big on terminology. These are the basic Earned Value Terms you need to know. If you are studying to pass the PMP exam you should know these by heart and be able to derive them in case you are heartbroken. They really are fairly simple. In order from first to last:

BAC = Budget at Completion (Project budget)
AC = Actual Cost of the Work Performed
EV = Earned Value
EV = Budgeted Cost of the Work Performed
EV = % complete times BAC
PV = Planned Value
PV = Budgeted Cost of the Work Scheduled
CV = Cost Variance
CV = EV - AC
CPI = Cost Performance Index
CPI = EV/AC
SV = Schedule Variance
SV = EV - PV
SPI = Schedule Performance Index
SPI = EV/PV
EAC = Estimate at Completion
EAC = BAC/CPI
ETC = Estimate to Complete
ETC = EAC - AC
VAC = Variance at Completion
VAC = BAC - EAC
