All formulas used in PM

Three-point estimates: (O+R (4) +P) / 6 = ((Optimistic Estimate + Ex.: O = 2 days. R= 4 days, P = 12 days, then
a) PERT (Program (or Project) (4 x Realistic) + Pessimistic Estimate))/ 6 PERT= (2+(4x4) +12)/6 = 5 days
Evaluation and Review Technique)
b) Standard Deviation (means range) (P-O)/6 (12-2)/6 = 1.7 days

Means the project will take 5 +/- 1.7 days
c) Triangle Distribution (average) (O+R+P)/3 = ((Optimistic Estimate + (2 + 4 + 12)/3=6 days
Realistic + Pessimistic Estimate))/3
Critical Path (the longest path)
Lack/ﬂoat/total ﬂoat (# of days that an Late Start (LS) – Early Start (ES) = LS – ES
activity could be delayed without causing Or
delay of the project) Late Finish (LF) – Early Finish (EF) = LF -
EF
Free ﬂoat (# of days that an activity could ES (of the next activity) – EF (current
be delayed without causing delay of the activity) - 1
next activity)
Forward Path (Mon to Fri) ES + Duration of the activity -1 = EF
Backward path (Fri to Mon) LF – Duration +1 = LS
Communication channels n* (n-1)/2 Ex: 10 stakeholders in the project, then
n= number of people in the project 10 * (10 – 1) /2 = 45 communication channels
between them.
Expected Monetary Value (EMV) EMV= Risk cost x Probability of the risk Ex.: cost of a new constructed house is 1,000. Risk
cost is 400, risk probability – 25 %.
Total cost of the risk Total cost of the risk = Initial cost + EMV Then, EMV: 400 x 0.25 = 100
Total cost of the risk: 1000 (cost of a new
constructed house) + 100 (EMV)= 1,100
Agile project Work in progress (WIP) / Throughput Ex. What would be the cycle time of feature A, if it
Cycle time requires 60 points of work and the team can
Note: Throughput = Amount of work that complete 5 points per day?
can done in a time period
Cycle time of A = 60/5 points per day = 12 days
