How to Identify Driving and Free Float Activities in Primavera P6
Normally a large Project comes with hundreds of activities and associated relationships, which together develops a critical path. As Project becomes larger, it become tough to analyze the effect that the activities might be having on one another. Only a Gantt Chart with Red Bars alone is not enough to determine which activity’s start date is more important. Certain Critical Activities that with a minor delay could cause important tasks start dates to slip.
Here come two terms ‘Driving’ activities and ‘Free Float’ that play important role in determining which activities require immediate attention.
In this article, we will learn how to find ‘Driving’ relationships and ‘Free Float’ activities in Primavera P6. By doing that, we will readily spot the activity/activities that are intruding an important activity start date.
How to Use Driving and Free Float
In order to find out which predecessor activity is driving the successor activity, or which predecessor activity determines the start dates of the successor activity? See the predecessor activities in the bottom details pan.
The predecessor tab in the bottom pan helps to find all predecessors to our important tasks and shows ‘Driving’ and ‘Free Float’ properties in the column. All you need to do is to customize the predecessor column and to add ‘Driving’ and “Free Float’ properties in the column.
In above figure, activity ‘B’ is checked marked to alert us that this activity will determine the start of the critical activity ‘E’. Similarly, ‘Free Float’ of Activity ‘C’ is 1-day only, and It is going to become a critical activity if 1-day free float is consumed, though it might not be a ‘Driving’ activity.
In a large project, it is difficult to analyze the activity relationships, these handy tools in Primavera help to locate the activities that require immediate focus.
