I am reaching out here because our client had a question and I had no answer for it.
Here is our case: We have a fairly large schedule (7000 activities) in P6 and we did duration uncertainty ranging for 454 activities near to critical path (TF<2weeks) also remaining duration more than 2 weeks.
Project duration is 2.5 years.
Results off of PRA risk analysis show 50% and 80% are only a week apart. Now client says that they use to see at least a month difference between P50 and P80.
Any thoughts why this is happening?
I appreciate your help.
