Advertisements

In the first part of this article we talked in general about the PMP exam and how to prepare yourself to pass it, in this part we will try to cover the most important processes and what formulas we need to memorize.

In total there are 42 processes all of them are important, and you need to study them all well, here I will list those that needs more attention:

Important Processes by Knowledge Area:

Important Formulas & Equations:

Term

Description

PERT (Three-Points Estimate)

(P + 4M + O )/ 6 Pessimistic, Most Likely, Optimistic

Standard Deviation (SD)

(P – O) / 6

Variance

[(P – O)/6 ]squared

Float or Slack

LS-ES and LF-EF

Cost Variance (CV)

EV – AC

Schedule Variance (SV)

EV – PV

Cost Performance Index (CPI)

EV / AC

Schedule Performance Index (SPI)

EV / PV

Estimate At Completion (EAC)

BAC / CPI,

AC + ETC — Initial Estimates are flawed

AC + BAC – EV — Future variance are Atypical

AC + (BAC – EV) / CPI — Future Variance would be typical

Estimate To Complete (ETC)

Percentage complete

EAC – AC

EV/ BAC

Variance At Completion (VAC)

BAC – EAC

To Complete Performance Index TCPI

Values for the TCPI index of less than 1.0 is good because it indicates the efficiency to complete is less than planned. How efficient must the project team be to complete the remaining work with the remaining money?

( BAC – EV ) / ( BAC – AC )

Net Present Value (NPV)

Bigger is better (NPV)

Present Value PV

FV / (1 + r)^n

Internal Rate of Return

Bigger is better (IRR)

Benefit Cost Ratio

Bigger is better ((BCR or Benefit / Cost) revenue or payback VS. cost)

Or PV or Revenue / PV of Cost

Payback Period

Less is better

Net Investment / Avg. Annual cash flow.

BCWS

The old terminology of Planned Value (PV)

BCWP

The old terminology of Earned Value (EV)

ACWP

The old terminology of Actual Cost (AC)

Order of Magnitude Estimate

-25% – +75% (-50 to +100% PMBOK)

Budget Estimate

-10% – +25%

Definitive Estimate

-5% – +10%

Communication Channels

N(N -1)/2

Expected Monetary Value

Probability * Impact

Point of Total Assumption (PTA)

((Ceiling Price – Target Price)/buyer’s Share Ratio) + Target Cost

Sigma σ
  • 1σ = 68.27%
  • 2σ = 95.45%
  • 3σ = 99.73%
  • 6σ = 99.99985%
Return on Sales ( ROS )

Net Income Before Taxes (NEBT) / Total Sales OR

Net Income After Taxes ( NEAT ) / Total Sales

Return on Assets( ROA )

NEBT / Total Assets OR

NEAT / Total Assets

Return on Investment ( ROI )

NEBT / Total Investment OR

NEAT / Total Investment

Working Capital

Current Assets – Current Liabilities

Discounted Cash Flow

Cash Flow X Discount Factor

Contract related formulas

Savings = Target Cost – Actual Cost

Bonus = Savings x Percentage

Contract Cost = Bonus + Fees

Total Cost = Actual Cost + Contract Cost
