Independent Float Formula:
| From: | To: |
Independent Float is that portion of the total float within which an activity can be delayed to start without affecting the float of the preceding activities in Critical Path Method (CPM) analysis.
The calculator uses the Independent Float formula:
Where:
Explanation: The equation calculates the independent float by subtracting the slack of an event from the free float of the activity.
Details: Independent float is crucial for project scheduling as it helps identify activities that can be delayed without affecting the overall project timeline or the float of other activities.
Tips: Enter Free Float and Slack of an Event values in days. Both values must be non-negative numbers.
Q1: What is the difference between Free Float and Independent Float?
A: Free Float is the time an activity can be delayed without affecting subsequent activities, while Independent Float is the time an activity can be delayed without affecting either preceding or subsequent activities.
Q2: When is Independent Float typically zero?
A: Independent Float is zero when the free float is equal to or less than the slack of the event, meaning there's no flexibility that doesn't affect other activities.
Q3: Can Independent Float be negative?
A: No, Independent Float cannot be negative. If the calculation results in a negative value, it's typically considered as zero in practical applications.
Q4: How is Independent Float used in project management?
A: It helps project managers identify activities that have scheduling flexibility without impacting other project elements, allowing for better resource allocation.
Q5: What are typical values for Independent Float?
A: Values vary by project but generally range from 0 days to several days depending on the project complexity and scheduling constraints.
