In which group of the following tools do the tools all relate to the same process

In which group of the following tools do the tools all relate to the same process?


A.  AON, GERT, PDM
B.  PND, PERT, GERT
C.  PND, PERT, Three-Point
D.  PDM, PERT, Three-Point

Please also briefly explain.

Thank you all.

I will go with Answer D.  None of the PMBOK Time Management processes use GERT.  Thus Choices A & B eliminated.  I did not see any reference in ITTOs to PND in PMBOK.  Thus C is eliminated.  We need and use all 3 of choice D to develop schedule.

I will go with answer A since all the three are diagramming methods.

AON and PDM both are same, got confused with GERT at what point they use in sequence activities process.

Answer is A.

Preetham, do you know when GERT is used sequence activities process?

Thanks,

The current version of PMBOK does not mentions about Gert. But anyway GERT is nothing  but Graphical Evaluation and Review Technique (GERT) which allows loops between activities. Example testing a software module after developing it
