Tracking and identifying changes to the critical, longest and driving paths is an important part of a Scheduler’s responsibilities. The term “Driving Path” is the generic term P6 uses within its database to flag the path that the User defines as either the Longest Path or Critical Path for the Project.
In the Driving Path Activity Comparison report shown below. Line item activities 64 and 65 were on the Driving Path in the Control Project, however, they are no longer on the Driving Path in the Modified Project. Item #66 remains on the Driving Path for both Project Updates.
Items 68 thru 73 were added as part of the Modified Project, TS-BL3-UP29. As a result of being added during Update #29, these activities now fall on the Driving Path. The added activities also removed activity line items 64 and 65 from the Driving Path and increased their Total Float value from 0 to 24.
In addition, Item 77 is no longer on the Critical Path is the activity was actualized.
The report lists the Activity ID, Activity Name, Activity Type, the Control Project’s Driving Path Flag, Remaining Duration & Total Float, the Modified Project’s Driving Path Flag, Remaining Duration and Total Float. The Variance between Total Float value is the difference between The Modified Total Float and the Control Total Float values.
