## Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

# Milestones and Risk Distribution

When applying uniform risk to all schedule activities imported from P6;

1. What happens to milestone activties?

2. As there are no distributions applied to milestone activities, will they form part of risk analysis?

3. Are milestone activities going to be part of distribution graph?

Yes.

The three important milestones are:

Substantial Engg. Complete ---- Mechanical Completion (Last portion) ---- Facility Turnover.

So the above milestones should be considered sequential milestones.

Hi Mathew

Welcome to Planning Planet.

These section milestones - are they linked to anything else in the schedule?

Best regards

Thanks Gary.

I am using Pertmaster. The EPC schedule was imported from P6. There is a Key Milestones schedule section with milestones representing commencement / completion of phases

Mathew,

Which software are you using? The below answers are assuming Pertmaster:

1. Not a lot, other than they are impacted by risk & uncertainties applied to activities upstream of the milestone

2. Since milestones are zero duration, uniform uncertainty distributions will not be applied

3. Yes. They will be impacted by risks and uncertainties upstream, so you will still be able to report probability distribution of milestones.

Cheers,

G
