The seventh step of a typical Oracle | Primavera Risk (Pertmaster) Monte Carlo analysis is to use standard risk reports for proactive planning and project management. This section will focus on generating and successfully presenting the tornado chart for project drivers.
The risk analyst will open the tornado chart in one of three ways:
Right-clicking on the graph gives the project analyst formatting options, copy options, and the advanced settings interface.
Right-clicking on the statistics will show options for formatting and copying the stats.
The Bookmark Visible Tasks button (Bottom-Right corner) will set bookmarks in the Gantt chart view. This will often help for quick mitigation scenario modeling.
Task uncertainty and risk events are coded in different colors. Risk events will be in red on all tornado charts.
The filter options include:
Which chart should I use? – The answer depends on what is trying to be shown, but duration sensitivity is often the best metric because it is simply showing the correlation between a driver and a reporting activity. I do not need to take the overall network critical path into account if I know that the milestone delivery is inherently critical. Flaws in logic, linked sub-projects, maintenance activities or reports after the project completion, and many other issues can cause issues with the calculation of the critical path. The duration sensitivity is not affected by any of that. The duration sensitivity will show the correlation between two activity durations to determine if one is driving the other. This is often the best metric for isolating a milestone and seeing what is driving its completion date.
