PERT : Triangular Distribution Vs Beta Distribution
PMBOK 5th Edition (Pg 206) gives the below 2 formulae for PERT calculations -
Triangular Distribution : cE = (cO + cM + cP) / 3
Beta Distribution : cE = (cO + 4cM + cP) / 6
In which question scenarios do you use each of the 2 to find the cost estimates
I have given a few mock exams, but never have I come across a question where the correct answer was derived with the Triangular distribution formulae.
In case if you have come across a qs needing Triangular Distribution, please let me know the qs.
