One Page Formula's for PMP Exam

From PMP Exam Resource, I have received the following email that I believe will be very valuable before taking PMP exam.:

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
--------------
6
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
____________
6

TASK VAR.  =   (P - O)  2   =   Std. Dev ^ 2
____________
6
_____________
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

P R O J E C T   S E L E C T I O N
---------------------------------
PV    =    F V   .
-------
(1+r)ⁿ

FV   =  PV  x (1+r)

NPV = S  (  PV  +    PV +   PV  +   PV   )
----     ----   ----    ----
(1+r)ⁿ   (1+r)ⁿ  (1+r)ⁿ  (1+r)ⁿ

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

E A R N E D     V A L U E     A N A L Y S I S
---------------------------------------------
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

------------------------------------------------------------

Good summary listing! You are doing a good job in helping PMP aspirants prepare for the exam.

Formula for Additional number of Communication Channels
This I derived on my own. Say if originally there are n people and x number is added then Cx=num of additional channels required=x*(x+2n-1)/2. This means if 1 person is added to the project than number of communication channels increases by n. Eg 6 people initially now one person is added. So no of additional comm channels=6

Forgot to Say thanks for the Sheet. Thank You
