Q: Fine tuning statistical distributions
We would like to fine tune some of the statistical distributions we use for our schedule risk analysis based on historical data. Typically we have been using triangular distributions, but based on our experience we think that this puts too much probability on the boundaries.
A: RiskyProject has many other distributions available, and you can to fine tune parameters of them.
You can fine tune or customize the statistical distribution for Schedule (as well as other parameters) in the Task Information > Distributions.
In the Distributions dialog, click the Duration tab. You can select a distribution from the Distribution drop down list. Depending upon your selection, you will be presented with distribution specific parameters that you can modify. For example for BetaPert you can modify the Mean or for LogNormal you can define the boundaries.
