Defining uncertainties for lags

[Fer23]

Do you have statistical distributions for lags and how are they defined?

[Intaver Support]

Yes, if you want to define a lag with uncertainty (has a most likely, low and high estimates) , you can add this to the predecessor in the Task Information > Predecessors tab.

When you create a predecessor link to a task, open the Task Information dialog box and click the Predecessors tab. Here you can add the Low, Base, and High estimates for the lag as well as select the statistical distribution type.

The issue here you cannot define any statistical distribution rather than uniform and triangular. I believe this is done to simplify everything because otherwise it would require a form to define distribution parameters. Uniform and triangular distributions don't require any parameters rather than low, base, and high lags.

[Intaver Support]

It is correct. RiskyProject uses forms (dialogs) to define distributions for multiple parameters, for example remaining duration. But for lags it does not have such dialog because very few people actually use it.
