Risk Percentile Calculation On Tasks With Risk Existence? (Primavera Risk Analysis)
Hi
Percentile Definition: Date, Cost, Duration etc associated with a confidence level. For example the P80 percentile for duration says you can have 80% confidence of achieving a certain value. If during analysis 80% of the time the duration was 5 days then this would be the P80 Duration percentile.
If a task uses a low Task Existence Risk say 20% (80% of the time task will not exist = 0 duration) should we expect the percentile calculation for this task to be reversed. Meaning the higher percentile values such as P80 will have low or zero values & the lower percentiles such as P20 will have higher values?
